Hardware stores offer us a huge assortment of various drilling machines in all price categories.
However, the cost of a really high-quality model hits the pocket, and buying a cheap one drilling machine from mass-market Chinese manufacturers, whose resource of work is ridiculous, there is no point.
It is much easier to buy a good electric drill, and make your own hand-made desktop home-made drilling machine based on it, which will fully meet all your requirements.
The cost of a quality drill is much less than that of a full-fledged drilling machine.
In addition, you can use an electric drill already on the farm, since the design of the machine provides for the possibility of its quick dismantling, which allows you to use one drill both in stationary and manual modes.
A tabletop drilling machine from a drill can be made on the basis of metal pipes, or based on wooden parts. We recommend that you give preference to the second option, since it is much less laborious and does not require the use of either a grinder or a welding machine.
Wood homemade machine has strength, which is more than enough for normal household use.
Such a do-it-yourself machine based on a drill, adhering to all the recommendations described below, can be done by hand within two hours, and it will serve you for more than one year.
In order to make a desktop drilling machine with your own hands, you will need the following materials:
The direct execution of the work occurs with the use of such tools:
To create a base base for a homemade drilling machine, use a hacksaw to cut a 20 * 30 wooden bar into four pieces, two of which are 17 centimeters long, and two more are 20 centimeters long.
If you want to create a homemade machine based on a massive electric drill, it would be better to make a larger base, since increasing its size will give the structure more stability.
Next, prepare a board with dimensions of 200 * 220 * 20 millimeters (the dimensions are given based on the above dimensions of the bar). Using self-tapping screws, connect the sections of the timber into one frame. To connect at each end of the beam, you need to use two self-tapping screws, if you use a beam of greater thickness, then you can screw it on a self-tapping screw at each corner of the end.
Place the board on top of the resulting frame. Fasten it with self-tapping screws around the perimeter of the timber, 2-3 bolts on one side will be more than enough.
To make your job easier, it is recommended drill preliminary holes in the boards, into which screws are much easier to screw in than into a solid board. To avoid protrusions of the heads of the self-tapping screws above the wooden surface, you can use a larger diameter drill to chamfer under their heads.
The width of the board for the column should correspond to the width of the created base, the thickness is 20 mm, and the height is determined depending on the size of the drill used, as a rule, a height of 40-50 centimeters will be more than enough. An excessively high column can negatively affect the stability of the entire structure.
After you cut the board suitable size, immediately attach it to the base with self-tapping screws. Next, you need to equip the free space between the column itself and the electric drill, for this, fix in the center of the upper part of the column, parallel to each other, two pieces of timber, measuring 25 * 35 * 17 millimeters.
In order not to make a mistake with the installation site, perform preliminary marking. Draw a straight line from the center point of the top of the column down, then step back 50 mm from each side of it, and draw two lines parallel to each other. The distance between the lines should be 100 mm.
Watch carefully so that the lines are strictly parallel to each other, so even the slightest angle of inclination of the trajectory along which the guides move is fraught with the fact that the drill will not enter the work surface at right angles, which is why thin drills will break very quickly when drilling hard metal surfaces ...
Installing the guides is perhaps the most difficult part of creating a drilling machine with your own hands. It is imperative that the guides run exactly perpendicular to the base of the machine and parallel to each other.
Prepare two boards measuring 100 * 250 * 20 mm, and mark on them the places where the sliding rails will be attached. Sliding rails sold in furniture stores are already equipped with holes for self-tapping screws, so you just have to screw them to the guides with your own hands. After the slats are attached, we mount the guides on the column.
We suggest that you make a universal mount with your own hands, which is suitable for installing not only a mini-drill, but also for a full-fledged electric drill. To do this, prepare a 60 * 100 * 20 board for the upper holder, and 100 * 100 * 20 for the bottom one.
Using a jigsaw, cut out a hole in the center of the bottom plank, the diameter of which is suitable for securely fixing your drill. Secure it to the rail using a furniture corner and self-tapping screws.
We also cut out the upper holder with jigsaws. Its size and shape are individual, and depend on which drill shape you will use. We make holes along the perimeter of both clamps and screw in the screws that will be clamped and motionlessly fix the drill in the holder.
The height limiter is necessary so that a homemade drilling machine can make multiple holes of the same depth. For creating a delimiter, the metal rod with M8 thread.
Drill a hole in the base in which the rod will be installed (it should be firmly fixed in the base, but, at the same time, rotate freely).
Next, we cut out a small piece of timber, drill a hole in it and install a threaded sleeve on one side, and a piece of a rod that will limit the range of motion of the guides on the other. We twist the beam onto the main rod.
For manual bench drill the machine was more convenient to use, you need to make a handle on the limiting rod.
This can be an ordinary homemade plywood stop, which is rigidly fixed between two nuts.
In order to save time, you can buy a ready-made inexpensive stand and vise for a drill in the OBI.RU store, which allow you to fix the drill in a vertical position and use it as a drilling machine, thereby increasing the accuracy and speed of work.
Characteristics:
»From the material presented by the author, you will learn how you can independently make a budget drilling machine from an ordinary electric drill.
Every artisan person would like to have a similar machine in his farm, because in comparison with factory counterparts it will cost ten times cheaper, and if all spare parts and components are available, then it is generally free.
The author of this machine is Igor Stasyuk, for which he is very grateful, he shared step-by-step photos of the assembly of the machine with the people. The design is quite interesting and at the same time simple. Corners and 4 legs are welded onto a base made of 3 mm metal sheet, a 500 mm rod from a profiled pipe is welded onto this plate square, the slider is made of 2 corners welded into the pipe and put on the lifting column with a gap so that the slider can move up and down the column. The lifting mechanism is driven by a cable stretched from the upper point to the lower one, and on the slider the cable makes several turns.
And so, let's take a close look at what exactly the author needed to assemble the machine? As well as the entire step-by-step process.

The process of creating a drilling machine from a drill.
And so, first of all, the author makes the base of the machine from sheet metal 3 mm, cuts out the workpiece using a grinder (angle grinder) And welds 2 corners and 4 legs from a steel rod or reinforcement into the lower part. The length of the legs should be the same, so that there is no skewing of the bed.
Corners and legs are welded.
Slider making! 2 corners are taken and applied to a square profile pipe that will serve as a lifting column and are pulled together with a clamp.
Along the edges it is seized by welding in order to just make a profit for now, and only then specifically boil a normal seam.
This is actually a blank.
The lifting column is made of a square section pipe with a length of 500 mm.
A bracket with a movable shaft is welded onto the slider body, on which the turns of the cable will be made.
IN drilled hole the thread is cut.
The lifting mechanism handles are made of reinforcement.
There is such a head on the shaft, which will be the base for the handles.
And so, 3 handles are welded for the convenience of raising and lowering the drill through the mechanism.
Installed on a lifting column.
At the end of the cable, such a loop is made.
I hope the lifting principle is clear and without explanation)
A square pipe is welded onto the corner.
Here is actually such a mount for an electric drill turned out.
Then the drill is installed and secured with a clamp of bolts and nuts.
Now let's go back to the lifting mechanism again.
A nut is welded into the upper part of the lifting column and a bolt is screwed into it, a cable is fixed to the bolt itself, and when the bolt is tightened and unscrewed, the cable is stretched to the optimal rate.
It is advisable to pre-lubricate the movable units with grease or lithol.
These small vise can be purchased at the hardware store in the tools section.
All parts were sanded by a master using sandpaper and then painted.
A self-made drilling machine allows you to drill holes in different materials at a sufficient quality level at home.
Drilling in an extensive list of all kinds of plumbing operations is considered among specialists to be the most accessible and truly simple procedure. It is usually performed on special drilling units, which may have different functionality and some design features. The modern machine tool industry produces many types of drilling machines, ranging from very simple (for example, a 2A135 machine) to CNC units that have several spindles.
It is clear that in most cases such machines are simply not needed for a home craftsman, since they are intended for performing serial operations. And in everyday life, it is usually required to carry out some single procedure.
It is for this reason that many home craftsmen decide to make an elementary drilling machine with their own hands, using those parts and improvised material that are available in any private garage.
As a rule, radio amateurs, as well as people who themselves perform simple household renovation work... In some cases, a simple electric drill is enough for this. But, if we are talking about more serious procedures, the drill, of course, is not able to guarantee the normal quality and accuracy of drilling. That's when it makes sense to start making your own mini-machine, on which you can install different types of drills.
In home workshops, such drilling equipment is most common, due to the simplicity of its self-made... You do not need high strength materials or any special fixtures. The Mini Hole Drilling Machine contains only four key components:
The stand is usually made from ordinary chipboard or from boards, since the small mass of the drill does not require the use of more durable materials... But it is better to make the frame as massive as possible. This will ensure that there is no vibration during the drilling process, which means more comfortable work.
Masters advise using a relatively thick (from 2 centimeters) furniture board for the base of the unit. The ideal option is the use of an old photo enlarger for the manufacture of the bed and rack. It will only need to be slightly modified to get a really reliable design for a mini-machine for domestic use.
The quality and accuracy of drilling on a home-made unit depends on the correct connection of the bed and the vertical rack. Therefore, this part of the work must be approached as responsibly as possible. It is recommended to cut two rails out of the steel strips, which are then screwed onto the rack. The block with the drill will move along the indicated guides.
The block itself must be made so that it reliably holds the electric drill. This is easy to achieve using small steel clamps. It is also advisable to place a small rubber pad between the shoe and the drill. It will significantly reduce vibration and make the operation of the unit more comfortable.
The feed mechanism of the drilling machine from the drill is the simplest lever that will move the block with the tool in the vertical direction. It is desirable to provide this mechanism with a spring of relatively high elasticity and power. One end of the spring should rest against a fixed wooden bar mounted on a rack, the other against a block.
If you want to achieve maximum convenience work with a home-made machine and do not plan to periodically remove the electric drill, it is recommended to simply disassemble its switch, and mount a separate button on the bed, with which you will start and stop your drilling unit. As you can see, everything is pretty simple. Any more or less "handy" man is able to make himself a small and convenient machine out of a drill.
Any owner in the garage, basement or somewhere on the balcony of the apartment has a lot of electric motors from electrical units that have served their time. Of these, it is quite possible to choose a motor that will become a mover for a mini-drilling machine. Ideal option in this case, an asynchronous type motor mounted on drum washing units is recognized.
The work of creating a home drilling machine based on an old electric motor is much more difficult than using a drill. But it is quite possible to implement them, armed with a certain amount of patience and perseverance. It is important to realize here that the engine from the washing machine has a more serious weight. And the power of such a "motor" is much higher than that of an electric drill. This means that you will have to take care of preparing the "mighty" rack and base for the machine being created.
Experts say that it is possible to reduce the vibration level of a unit based on an asynchronous motor by installing it on a strong base, as well as by placing it closer to the vertical rack. But it must be remembered that the close location of the rack and the motor is fraught with the complication of the design of a home-made machine, which is caused by the need to install belt pulleys.
For the manufacture of a drilling machine using an electric motor from a washing machine, among other things, you will need the following parts:
A hexagon is required to make the movable part of the machine tool transfer device. A pulley will be put on it. Also, a metal tube with a bearing and a steel ring must be attached to the hexagon. It is important to achieve a very tight connection of these components with each other, since otherwise, during vibration, they will completely collapse (not immediately, but quickly enough).
The adjusting complex of the unit is made of a gear and a tube on which cuts need to be made. These include the gear teeth. The specified tube is made of such a height that the drill chuck is lifted by a predetermined amount. An axle with a hexagon is then pressed into the same tube.
It can be seen from the described diagram that it is rather difficult to manufacture a machine with an asynchronous motor. Therefore, it can be advised to do it by analogy with the previous process, when an electric drill was used. But be prepared for the fact that, unfortunately, the resulting machine will not be characterized by special drilling accuracy.

You don’t have to spend money on a bench drill, because it’s not that hard to do it yourself. To do this, you will need to purchase, manufacture or use used parts. We will tell you about creating several structures, and you can choose your model for assembly.
Almost every owner who builds or renovates his house or apartment, who repairs household and garden equipment, and various crafts made of metal and wood, has a drill. But for some operations, a drill is not enough: you need special accuracy, you need to drill a hole at right angles in a thick board, or you just want to make your work easier. This will require a machine that can be made on the basis of various drives, machine parts or household appliances, and other available material.
The type of drive is a fundamental difference in the designs of homemade drilling machines. Some of them are made using a drill, mostly electric, others - using motors, most often - from unnecessary household appliances.
The most common design can be considered a machine made of a manual or electric drill, which can be detachable, so that it can be used outside the machine, and stationary. In the latter case, the switching device can be transferred to the bed for greater convenience.
The main elements of the machine are:
The base or frame can be made from a solid saw cut of hardwood, furniture board or chipboard. Some people prefer a metal plate, channel or Tavr as a base. The bed must be solid to provide structural stability and to absorb vibration when drilling for accurate and accurate holes. The size of the bed made of wood is at least 600x600x30 mm, of steel sheet - 500x500x15 mm. For added stability, the base can be made with eyelets or bolt holes and attached to a workbench.
The stand can be made of timber, round or square in cross-section steel pipe... Some craftsmen use the frame of an old photographic enlarger, a substandard school microscope, and other parts with a suitable configuration, strength and weight as a base and stand.
The drill is mounted using clamps or brackets with a hole in the center. The bracket is more reliable and gives more precision when drilling.
The feed mechanism is needed to move the drill vertically along the rack and can be:
Depending on the type of mechanism adopted, the type and structure of the rack will also differ.

A steering rack for a car and a drill are quite massive products, so the bed should also be massive and, preferably, with the ability to fix the machine to a workbench. All elements are performed by welding, since the connection with bolts and screws may not be sufficient.
The bed and the support leg are welded from channels or other suitable rolled products, with a thickness of about 5 mm. The steering rack is attached to the rack, which should be 70–80 mm longer than the rack, through the steering column lugs.
To make the machine more convenient to use, the control of the drill is placed in a separate unit.

The order of assembly of drilling table machines:
All fastenings must be made as securely as possible. It is advisable to connect steel one-piece structures by welding. When using any kind of guide, make sure that there is no lateral play during movement.
Advice! To fix the part in which the hole is drilled, the machine can be equipped with a vice.
You can also find ready-made drill stands on sale. When buying, you need to pay attention to the weight of the structure and the size of the working surface. Lightweight (up to 3 kg) and inexpensive (up to 1.5 thousand rubles) racks are suitable for making holes in a thin plywood sheet.
If there is no drill on the farm or it is not desirable to use it in the machine, you can make a design based on an asynchronous motor, for example, from an old washing machine. The scheme and manufacturing process of such a machine are quite complex, so it is better to do it by a master with sufficient experience in turning and milling work, assembling electrical circuits.
To get acquainted with the design, we present assembly drawings and detailing, as well as the characteristics of assembly units in the specifications.

This style reminded me very much of the movie The Great Gatsby, in which the interiors of houses and apartments in the 1930s were very luxurious and pompous. Of course, it was a prerogative.
In the household, a home craftsman should have a set of all the tools, and therefore a do-it-yourself drilling machine is the unit that will help him to further expand his functionality.
Many for drilling various holes in everyday life can be satisfied with an ordinary drill, however, the capabilities and tasks of even the simplest drilling equipment are more global.
A bench-top drilling machine, in addition to drilling, countersinking and reaming, can also mill (there is a milling unit), as well as grind various surfaces as well as perform a number of other tasks.
Such equipment is especially important for radio amateurs, who with the help of it can solve a number of their narrowly focused tasks.
Such a unit for a home workshop can be bought at any specialized store, but it costs a lot, and not every master will find extra money to purchase a professional drilling machine, which is shown in the photo below.
Meanwhile, if you wish, you can assemble a homemade drilling machine for drilling wood and metal with your own hands from an ordinary drill.
Of course, you will have to spend personal time on making the machine, but the result is worth it.
Desktop homemade drilling machine in a mini version for wood and metal, if you have all necessary materials, everyone can do home master.
Drilling a variety of holes in everyday life is carried out, as a rule, with the help of a hand drill, which is in the home workshop of every skilled owner.
Meanwhile, even at home it is not always possible to achieve the desired result by using an ordinary drill.
In this case, the question arises to make a mini vertical-horizontal drilling machine for wood and metal with your own hands.
Such a universal unit is simply necessary for those who are engaged in radio electronics for drilling small holes in printed circuit boards, which cannot be done with a hand drill.
In addition, a homemade drilling machine will not interfere and, if necessary, drill through and blind holes in different types materials.
With it, it is very easy to perform reaming and countersinking, as well as, if necessary, cut threads.
If you additionally install a milling unit on it, then the capabilities of the unit will expand even more.
The milling unit will make it possible to perform a variety of simple operations for vertical-horizontal milling of the most different materials.
An add-on mini drilling unit for drilling printed circuit boards can be made from the most ordinary drill, however, to solve more complex problems, you will need a more structurally complex device, the same milling unit.
Any professional drilling unit consists of several mandatory elements, which include such as a drill, countersink, tap, and reamer.
A do-it-yourself mini add-on machine must also contain all these components.
If the drilling machine with his own hands is assembled according to all the rules, then the home craftsman can easily, using the milling unit, in addition to drilling printed circuit boards, cut and bore a hole with the required diameter, grind it precisely, and also perform a number of other specific tasks.
Before proceeding with the assembly of the unit, it is recommended to carefully study the existing types of drilling machines and understand the basic principle of its operation.
The video posted above shows a homemade drilling unit at work, which can also be used for drilling printed circuit boards.
Currently on industrial enterprises and in everyday life, a huge number of various modifications of drilling equipment are used.
Many of them are designed to solve exclusively professional problems, and for home use just don't fit for various reasons.
In the photo below, you can see an industrial drilling machine.
Today you can find spindle machines, semiautomatic machines, vertical drilling, as well as many other types of units.
For domestic use, a mini-additive unit capable of solving simple tasks is suitable.
For example, if the machine is needed mainly for drilling printed circuit boards, then you can assemble it from the most ordinary drill.
Like any other equipment, industrial drilling units have their own special designations and markings, which can be used to determine their type and main purpose.
The most popular devices, which are found most often, are spindle devices, as well as units for radial and horizontal drilling.
A very popular coordinate unit is designed for boring workpieces.
All drilling equipment can be safely attributed to the universal type. For a home workshop, it will not be difficult to make a universal-type mini-additive unit with your own hands.
If desired, a homemade coordinate unit can be automated as much as possible and supplemented with various devices, which will only add general functionality to it.
Depending on the functional purpose, each drilling machine, including the coordinate one, consists of a certain number of elements.
Any unit of this type, including homemade ones, necessarily consists of a bed, a steering rack, and an engine. The photo below shows a homemade mini-drilling unit.
The drilling machine is a type of industrial equipment designed to solve narrowly focused tasks.
It must include a transmission mechanism, control and working bodies, as well as a sufficiently powerful electric motor.
Each mechanism that is part of this equipment has its own purpose, which determines its functional tasks.
So, the transmission mechanism is designed mainly to transfer the necessary movement to the working bodies, directly from the installed engine.
In this case, the working body is a drill, which is attached to the chuck, which, in turn, is connected to the spindle and the rotating shaft.
In a machine of this type, rotation from the engine to the working bodies is transmitted by means of a belt drive. In order for the drill to be in a given position, a rack and pinion gear associated with a special handle is used.
It is imperative that such a machine, even if it is assembled from a drill, must have buttons in an accessible place that are responsible for turning it on and off.
Machines of this type have a fairly simple device, moreover, that they can perform a huge number of very different functions and solve many narrowly focused tasks.
When assembling such a machine with your own hands, for a higher accuracy of performing work directly on its moving part, it is recommended to place a special scale.
It will help control the depth of blind holes. It is also best to make such a machine on which it will be possible to change the rotation speed of the chuck, depending on the tasks being performed.
The work table should be made exclusively of a solid metal plate rigidly fixed to the base.
The video below shows a homemade drilling unit with which you can drill printed circuit boards and more.
A drilling machine assembled according to all the rules will be able to successfully drill holes of various diameters, including micro ones, with great accuracy, which is especially important for printed circuit boards.
Despite the apparent simplicity, you need to work on it in compliance with generally accepted rules.
So, just before starting work, it is necessary to check the availability of power in the network, the integrity of all equipment, and also to clear the desktop of all unnecessary.
There must be a vice on the table itself, with which it will be possible to conveniently fix the workpiece.
Before starting work on the part, it is necessary to mark the future hole in accordance with the drawing, then set it in a vice on the table and clamp it firmly.
Next, the drill is fixed in the chuck and a test run is done. Homemade vise for a drilling machine, which are used during work, must have certain dimensions, including in order to work with micro holes.
During the test run of the machine, it is necessary to check the rotation of the drill and make sure that it rotates without circumscribing a circle.
This is especially true when drilling micro holes. At the time of drilling, the handle should be influenced with smooth movements, while the drill must be periodically cooled.
Drilling of micro holes should be done with special precision, for which the coordinate pointers should be used.
Upon completion of the work, the drilling machine should be turned off, unclench the vice and take out the finished workpiece. The video above shows the principle of operation on the machine.
The easiest way to assemble an additive drilling machine without a steering rack is to use an ordinary drill.
In this case, it is necessary to make the table massive in order to minimize the vibration of the machine during operation. A stand for a drill can be made from both chipboard and metal corners.
First, you need to connect the stand and the table to each other at a right angle, while the drill should be secured with clamps. A driving mechanism should also be provided.
A vise must be attached directly to the table, in addition, the on and off button must be in a prominent place. In the video below you can see the manufacture of a machine from a drill without a steering rack.
You can assemble a more complex and functional machine with a steering rack for drilling from the engine from the washing machine. This device will allow, among other things, to check micro holes with great accuracy.
In this case, the desktop should be even more massive, since the vibration during operation will be strong enough.
Particular attention should be paid to the moving part of the unit, and for these purposes it is better to use ready-made drawings. It is recommended to connect the motor with the chuck using a belt drive.
If all the steps are performed correctly, then such a machine will be able to drill even micro holes with great accuracy.
The video below shows a homemade machine powered by a washing machine motor, which will come in handy in your workshop.
It is advisable to make a drilling machine with your own hands in those situations when in a home workshop or garage it becomes necessary to drill holes in parts of various configurations, as well as made of different materials. It should be noted that such a device makes it possible to obtain holes with sufficient high level quality.
One of the options for the homemade drilling machine
In manufacturing or repair enterprises, where the drilling operation is considered the most common, a special device is used to perform it, the models of which can have different functionality. So, it can be a compact benchtop drilling machine, characterized by the simplest design, or equipment equipped with several working spindles and numerical control.
The main structural elements of a homemade machine
For drilling holes in various materials, which is performed in a home workshop or garage, you can use DIY equipment. Naturally, for home use, you need a simple device that can be made from components and materials found in almost any garage or home workshop.
And in this article, we will not leave unanswered the question of how to make a drilling machine at home, while spending a minimum of funds. The drawings and the experience of many masters who have already gone this way will help us in this.
The need for such mini drilling equipment for metal, wood or plastic most often arises for those who are used to independently performing various repair work in their house or apartment. Also, quite often, radio amateurs are puzzled by the construction of miniature drilling machines.
It would seem that an ordinary drill can be used to perform such an operation, but such a tool is not always able to provide the required quality and accuracy of drilling operations. Homemade drilling machine. in addition to its compactness, it has another important quality: it can be used for various types of drills.
Simple mini drilling machine for small jobs
To make a small but functional drilling machine for your home workshop, you do not need to purchase special materials and components. The design of such a convenient and useful desktop device contains the following components:

The stand on which the drill will be mounted can be made from a chipboard sheet. This material quite capable of supporting the weight of such a device. The bed of such a mini machine should be more massive, since it protects the entire structure from vibrations, which can adversely affect both the quality and accuracy of the hole obtained, and the comfort of work.
As a material for the bed of such a drilling and filler machine, you can use an ordinary furniture board, the thickness of which is more than 2 cm. It is most convenient to use the base of an old photo enlarger for this, slightly modifying its design. Sometimes an old microscope is used, but this is a rather rare option, since such an assembly will not be large enough and its use will be limited.

What quality and accuracy a homemade drilling machine will provide depends mainly on how correctly and reliably the connection of its base and vertical rack is made. Important elements of such a micro machine are two guides along which the block with a drill fixed to it will move. These rails are best made from two strips of steel, which must be securely screwed to the rack with screws.
When making a block, it is advisable to use steel clamps that will securely fix the drill on it. In addition, in order to avoid unwanted vibration processes during drilling, a thick rubber gasket must be installed at the junction of the shoe and the drill.
After that, you need to make a feed mechanism for such a mini machine, which should ensure the movement of the electric drill in the vertical direction. The schemes for the manufacture of such a mechanism may be different, but it traditionally contains a lever and a spring in its design, which is attached at one end to the rack, and at the other end to the block with a drill. This spring makes the feed mechanism more rigid.
A drilling machine from a drill, which is not planned to be removed from it, can be made more convenient in operation if you disassemble the native switch of the drill and mount a separate button on the bed of the mini equipment. Such a button will always be at your fingertips and will allow you to quickly turn on and off the device. As you can see, a drilling machine from a drill is not at all difficult to make, for this it is quite enough to carefully read these instructions or watch the training videos in this article.
As an example, consider in more detail one of the options for a homemade drilling machine from a drill. collected at home.
Self-assembled drilling machine from a drill
The absence of an extra electric drill in the household is not a reason to abandon the idea of making a drilling machine with your own hands. Any electric motor can be used to drive the rotation mechanism of such equipment. Such engines, which were previously installed on various equipment, will certainly be found in the garage or workshop of any home craftsman.
Asynchronous motors, which are equipped with washing machines, are best suited for the manufacture of a mini drilling machine. If you have such a motor, you can confidently apply it to your home drilling equipment. Making drilling equipment with such an engine at home is somewhat more difficult than using a drill, but the power of such a machine will be much higher.
Given the fact that an induction motor weighs more than a conventional drill, you will need a more powerful base and stand to accommodate the feeder.
In order for such a mini drilling and filler machine to vibrate less during operation, it is necessary to install the engine on a strong base and place it as close to the rack as possible. But here it is important to maintain the correct distance, since the convenience of mounting the belt drive depends on it, due to which the rotation from the engine will be transmitted to the drilling head.
In order for you to be able to make such a machine at home, you will need the following structural elements:
The hexagon also connects to the metal tube, bearing and clamping ring. Such a connection must be very reliable so that the resulting assembly does not collapse during operation.
Drilling machine with asynchronous motor
The mechanism necessary to ensure the supply of the tool in such a mini machine should consist of a tube, on which cuts are made, and gears. The tube will move by connecting its teeth to these cuts. In this tube, the height of which must correspond to the value of the required feed of the tool, then an axle with a hexagon is pressed.
Consider one of the very serious options for a home-made drilling machine with an asynchronous motor, clearly made by no beginner. Few home craftsmen take the risk of taking on such a project, but if, as they say, itchiness, then nothing is impossible.
Difficult to manufacture homemade machine with an asynchronous motor
It is quite obvious that it is quite difficult to manufacture such a machine, and then it is even more difficult to ensure the accuracy of its operation. therefore the best option is the use of an electric drill to make a home drilling machine.
Finally, we suggest watching a couple more videos in which the craftsmen demonstrate their homemade drilling machines. These videos once again prove what to collect with my own hands the necessary equipment is always real, even if it is not easy at times.
When performing carpentry and locksmith work, an appropriate tool is usually used, developed for specific tasks. However, there are situations when it is much more convenient and easier to use special machines. They allow you to optimize the process and save time with the same type of work. Therefore, questions about how to make a drilling machine from a drill very often arise from modern craftsmen.
First of all, it should be said that it is very convenient to use such a device when making holes in small horizontal planes. It almost completely eliminates the backlash of the drill, which necessarily occurs when handmade... Even a small drill greatly improves the accuracy of the hole being drilled, minimizing error. Also, such equipment saves a lot of time and effort if you need frequent use or monotonous work.
Almost all enterprises that carry out locksmith work are equipped with such units. The fact is that research in the field of labor protection has shown an increase in productivity and quality improvement when using them. Some of them even purchase a magnetic drilling machine to optimize production on large planes without the use of expensive equipment.
Currently, there are many designs for creating such equipment at home. However, most experts recommend making a drilling machine from a drill. This is due to the fact that this tool already completely contains all the necessary components and assemblies, and they do not have to be purchased separately. In this case, the fixation on the structure is performed so that the drill can be easily removed for independent work. As a result, we do not lose a tool that we can use on our own.
In order to create a drilling machine from you need to purchase the tool itself. It is selected in accordance with the parameters that the finished device will have to have. At the same time, experts advise paying attention to products that have their own small backlash. Otherwise, the feasibility of using it for work is questioned. You may also need:
In this case, the selection of the used tool depends on the material for creating the frame. However, it should be noted right away that a corner for measuring the connection of elements at 90 degrees will be necessary in any case. Even a mini-drilling machine requires great precision in its manufacture, since this will subsequently affect the quality of the holes being made.
First of all, you need to decide on the design of the final product and the material for its manufacture. However, there is no need to come up with too complicated technical solutions or expensive knots. A typical drawing of a drill from a drill is quite simple. It involves the creation of a solid and stable base on which a vertical tripod with a movable carriage is mounted. Considering this, special attention should be paid to the implementation of the movement of the drill in the vertical plane, although the use of ready-made guides greatly simplifies this process. If you use a microscope stand, a photomagnifier or a press as a frame, then the drawing will be based on their base, and the entire manufacturing process is greatly simplified.
Even a mini drilling machine needs a stable base. It must not only hold the entire structure, but can be equipped with various elements for fixing tools or other devices. Thinking over the device of the drilling machine, it is worth listening to the advice of experts. Many craftsmen recommend creating these devices from wood. Therefore, a wooden frame in the form of a small box is used for the bed. It has seats for installing a vice or other structures. If the product is planned to be used on large surfaces, then the bed is made of a solid plate with a hole for a drill. This is how the principle of drilling through can be realized.
Almost any device of a drilling machine involves the installation of a vertical tripod at an angle of 90 degrees to the bed. Therefore, in work it is very important to use an accurate one. You also need to make a reliable fixation of the tripod using additional mounts in the form of corners.
If the work is supposed to be done at a certain angle, then certain devices can be made in advance that will be attached to the bed. Most often, in such cases, ready-made ball vices with an adjustable angle of inclination are used.
When a homemade drilling machine is made from a drill, then this stage must be given special attention. The fact is that the vertical stroke should be soft, without distortions, backlash or displacements. Taking this into account, professional masters recommend using ready-made guides that can be taken from other devices. You can also use systems made for pulling drawers near cabinet furniture. They are quite reliable and can withstand heavy loads.
The guides are installed directly on the tripod or special strips attached to it. In this work, it is very important to use a measuring tool, since these elements must also be located at an angle of 90 degrees in relation to the bed and parallel to each other. Even slight distortions or displacements should not be allowed.
The second part of the guides is fixed on a special carriage, where the drill itself will be installed. It is made of wood and adjusted to the size of the original tool. Also, a small handle is attached to the carriage, with which the operator will control the movement process.
For implementation return movement and to facilitate the control of the carriage travel, a spring is installed on the machine. One end of it is fixed at the top of the tripod, and the other is mounted on a movable mechanism. At the same time, the level of its tension is immediately checked, which, if necessary, can be changed by cutting the turns or stretching them. However, this adjustment is best done under load, which means that it is performed only after fixing it to the drill carriage. Some craftsmen recommend making the spring removable, it could be removed after work. So it will not stretch and weaken.
Usually, instructions on how to make a drilling machine from a drill recommend creating special fastening systems that are ultimately very difficult to work with. However, if the tool is selected correctly, it can be secured using conventional plumbing clamps used to create a hose-to-pipe connection. In this case, you will need to make certain changes to the shape of the carriage or even slightly tweak the drill body.
It is very important that the tool is clamped tightly and moves in the clamp. Therefore, even at the stage of manufacturing the carriage, practically no free space is left for it, limiting it from all sides structurally. In fact, the carriage itself is a kind of drill bed, in which it will sit very tightly. Additional elements are needed only for the reliability of fixation. This approach will greatly simplify the design and allow you to quickly remove the tool if necessary.
Given the material outlined above, we can conclude that a drilling machine from a drill can be made independently and without large financial costs. At the same time, the final product will be maximally adapted to the implementation of specific technical tasks and will be able to satisfy the corresponding requests of the end user. However, it is worth considering the fact that factory designs usually have less error and are able to perform accurate work with a minimum tolerance. Therefore, such devices are usually suitable for private use or in small workshops where high precision holes are not required.
Those who have ever used an electric drill have encountered difficulties when it is necessary to make a bunch of holes. Floor of trouble if there are holes in the board, but holes in the metal? For this, the industry came up with a drilling machine. Those who have it are very lucky, and those who do not have it - get your pocket ready.
My pocket, personally, is small, so I can't afford a factory drilling machine. Well, Chinese, made of tin, I can certainly afford it, but it's bullshit. Soviet, semi-complete, are unreasonably expensive. I did not consider shop racks for drills, in principle, they are too "childish". Browsing the Internet, I found a lot of homemade products, but the presence of turning works stopped. You can order a couple of parts from a turner, but no one wants to share normal drawings, and when you design a part, a jamb will always come out yourself. The jamb got out - run again to the turner and ask to fix it. But one day I stumbled upon interesting video from Zhelezjaka about a homemade drill stand. Simple design, repeatable and versatile. At the moment of watching a video from Zhelezjaka there were no analogues of this design yet.
I was going to do this rack for a whole year, maybe more. After going on vacation, I finally got to work. He made his own adjustments to the design, they do not fundamentally change the machine, but they unify materials and reduce the production time of some elements. I tried to use the minimum amount of purchased material, tried to use the garbage that I had. But it still didn't go without shopping. From the main one, I bought a pipe for the guide, a corner and a strip, each position 1 meter.
Now we are looking at the manufacturing process. Actually, the guide for the carriage is also made of a square tube 40x40x3 mm. I bought iron in a small hardware store, rolled metal is stored there practically in the open air and does not really shine in quality. But this has one advantage, there you can feel everything and choose a better one. And so it happened. From the beginning I wanted to take a pipe with a wall thickness of 2 mm, but we could not choose an even piece with the seller. I took it with a wall thickness of 3 mm, thick-walled pipes are much smoother. Steel is steel and traces of corrosion are an integral part of it. Therefore, I had to clean almost all the rental, especially the guide. I didn't bring myself to a state of feline pride.
I forgot to say, in advance I prepared a set of preliminary drawings, according to which I made the basic elements. A set of final drawings will be posted at the end of the article. Cut to size mode. Here is the first deviation from the author's project, I took the corner for the carriage and bracket 45x45x4 mm. A 40x40 pipe fits perfectly into it, nothing needs to be cut and an excellent mounting gap is formed (seen in the photo below). He tried to repeat the author's technology.
I put sandpaper on it, squeezed it with clamps on the guide, welded everything from the heart. And then take off the figurines, squeezes so that "mom do not cry"! I was able to remove the strut bracket only by knocking it over the rest of the 45th corner. Then I cut the whole corner, welded the carriage, put twice as much sandpaper and that's it .... How many swear words were spent, smoked cigarettes and damned everything that moved next to you can no longer remember, but it was not possible to separate one from the other. As for the author, everything is so simple, I don't know. And the technology, in my opinion, should be as follows: put in double-folded sandpaper -> squeeze with clamps -> weld the edges in all four corners -> completely boil one of the edges -> let it cool completely -> try to remove it from the mandrel. If it came off the frame, then we boil the second edge. If it does not work, then cut off the tacks on the not welded edge and slightly remove the guide. In the photo below there are already welded blanks, the smallest will not be used.
I made Stanin out of what was. And I had almost a meter of channel 8. I adjusted the length of the bed to the length of the remainder of the square pipe, which remained after the manufacture of the guide. Below is a picture of the installation process of the rack bracket. To be honest, this design of the bed is not very good. The shelves at the channel are all curves, one piece has a concavity, the other has a convexity. Horror, not hire. He pretended to set it at a right angle, though it is not clear to which plane. I will deal with perpendicularity later.
and back. The rear panel has two threaded holes. These holes will serve to fix the machine in a horizontal position when working with wood.
And fasteners to secure the rack in an upright position. A lone bolt is welded to provide grounding. Holes for wires are not visible here, but they are in the drawings.
About the leveling feet. There were no standard legs from a refrigerator or a washing machine, by some coincidence, I am amazed. I had to make it out of a bolt and an enlarged washer, the issue price is a couple of cents. But those things in which the legs are twisted I had, but high nuts are perfect for them.
The drum, the one that will scroll the cable. I approached the manufacture of this part creatively. It works the same way, but it is done differently. Steel bars with a diameter of more than 10 mm are difficult to find in a home shed and my shed is no exception. Plus, immediately solved the issue of a removable handle. As an axis, I used an M10 bolt with a short GOST thread. Having cut off the excess from it, I got a smooth axis. The head of the bolt will serve as a kind of engagement element between the axle and the handle. The outer part the drum will serve water pipe... If you do not have such a pipe in the metal waste, then it can be replaced with a squeegee purchased at the nearest plumbing store. To center the axle, bushings had to be made, so to speak, by hand, without lathe... To do this, he clamped two M10 nuts on the remaining trim of the bolt (do not discard the trim, it will come in handy later), inserted it into the drill and grinded the entire structure on an electric grinder. Since the thread on the bolt trim is no longer there, the thread in the bushings must also be drilled out. An M5 threaded hole is made in the head of the bolt for attaching the handle. It worked out pretty well.
In the picture below, I have already welded the bushings to the axle, the main thing is not to forget to first put on one of the lugs. Holes are made in the outer cage of the drum through which the cage will be welded to the bushings. All dimensions and clearances are shown in the drawings.
Here's the result:
Carriage. There is nothing special to tell, we collect everything according to the drawings. Only one addition. In the original, the carriage is locked with one of the adjusting bolts. They are, after all, adjusting, so as not to touch them, so after welding all the parts, I made an additional threaded hole just for the locking bolt. I made the thread for the adjusting bolts only with a rough tap to get rid of spontaneous untwisting.
View from the other side. Sorry for my welds, I cook as well as I can.
A handle, it is a lever. Do not throw tomatoes after looking at the photo. In my version, the lever is made of a 17 spanner spanner. It had a burst cape, so I gave a second life to the undercloak.
On the one hand, I welded a homemade washer from the strip onto the cap of the key.
Further element which is not in original design Is an emphasis. This stop is attached to the top of the rack rail and is used when fixing the machine in a horizontal position. The holes for fastening to the rack are not aligned to minimize the rotation of the stop.
Another ode to a new detail. I named it “table”. Since there is no plane at my bed, I had to dodge. It is made from a piece of laminated chipboard, not the best option, but so far. With the help of screws, I have the opportunity to set the work plane perpendicular to the rack.
This is how it looks. The photo also includes an auxiliary carriage, on which a ruler and a hand-tool for woodworking will be placed.
And here you can see the element for adjusting the table.
It's time to make a drill bracket. And again, the materials that I had were used. Clamp from a strip of 25x4 mm, removal from the pipe 30x30x2. This strip fits perfectly inside the pipe, which makes it easier to attach one to the other. And this rotation of the clamp ensures perfect alignment. The clamp is made by tapping a strip around a pipe with a diameter of 40 - 42 mm.
A little closer.
And brew it neatly. I was worried about the quality of these seams, since this place is the weakest in the whole structure.
Let's put aside the welder for a while and get busy with the drill. As I said, I was going to make the machine for a whole year. During this time, I got a drill, which is not a pity. It was presented to me as not working. Inside, a wire was simply transmitted and over time in this place it burned out. I straightened the wire, but the drill, as you can see, is very tired and full of backlashes. The first step was to replace the cartridge and rolling bearings. The liner bushing was also broken.
To be honest, I would have ripped off the hands of these designers, who added a ratchet function to a simple drill. Zero sense, the bearings breaks and adds to all the delights of the axial movement of the chuck. The most interesting thing, at least in this drill, is that the ratchet assembly is the same size as the outer race of bearing # 608. My attempts to knock out the ratchet from the silumin holder were crowned with failure, I had to cut the teeth with a hacksaw and go to the market to look for a bronze bushing. And on the market for this sleeve they broke an awkward price, which I was very offended and basically left with nothing. In place of the bronze gold bushing, the inner race from the same 608 bearing fits perfectly in size. One thing is bad - this replacement is one-time, next time you will have to change the sleeve together with the chuck shaft. Let's see how long it will live. To eliminate the axial movement of the shaft, instead of a repulsive spring, I installed a sleeve made of a plumbing fitting, and on the other side I placed a turned washer. The bearings are replaced, the backlashes are eliminated, the mechanisms are lubricated.
Attention, the faint of heart, please do not look at the following picture! Since this drill was specially prepared for the machine, I tried to make it so that it could only work in this machine. I cut off the handle. From the barbarian ... The start button was removed, the reverse lever remained in its original place, the cut was covered with a neat lid.
And what I got in the end. I placed the button in the cavity of the bed, made a threaded hole in the front panel and tightened the adjusting screw there. Thus, I received a remote speed control unit. You tighten the screw, it gradually presses the button that changes the speed of the drill. Separately mounted the toggle switch for turning on the machine.
Below is the process of assembling the spindle bracket. In the chuck, I fixed the guide from the printer, which made it possible to relatively accurately align the tool axis perpendicular to the table.
Here is the brazed bracket. Immediately made a hole in the table and bed. In the bed, I cut a thread for screwing in the center to hold a wooden blank during turning work. Then he began to procure parts for the manufacture of a handyman (Handyman is a stand for a cutting tool on a lathe).
And here he is ready. It turned out to be of simplified functionality, there is no height adjustment. I have never worked on a wood lathe in my life, and on metal, too, I will learn and try.
And, in principle, the machine is ready, almost the maximum load was chosen for the test. The first serious hole was made with a 13 mm drill in the front panel of the machine for installing a toggle switch, let me remind you that the panel is made of a 4 mm thick strip. The result exceeded all expectations, without preliminary drilling and a minimum of effort, without even straining, drilled a hole in a matter of seconds. I was glad, the state of euphoria passed and noble traces of young rust began to catch my eyes. I was in a hurry to collect everything and did not bother to paint in detail. We'll have to disassemble everything now.
As always, I waited for a cold snap to start painting. Therefore, I had to paint in the barn, the pleasure is not pleasant, paint on the street. I chose green color, this association from childhood - if the machine, then green.
Bed painting. It was too lazy to take out the wire, a collective farm is a collective farm.
The paint has dried and here is the result of the work:
On the other side:
And in the lathe position:
Here are the promised drawings. I ask all normokontorolerov and very smart ones not to comment on the drawings, and not even look :)) joke. Use it to your health! I even made a specification for which you can estimate the amount of materials needed. But I must warn you, do not blindly believe the drawings, double-check, I am not a robot and I can sometimes make mistakes.
The result is a great tool. I still cannot fully evaluate the lathe version, since I only have a chisel in place of the cutters. But as a drill, there are a couple of "buts":
And do not forget to use personal protective equipment when working. Do not violate safety requirements, no matter how silly and ridiculous they may seem.
