It is possible to drill a hole in a stone as strong as granite, but it is necessary to thoroughly prepare for this difficult procedure. For drilling, you will need not only a drill for granite, but also a set of appropriate tools and accessories. The workplace should also be properly prepared.
What is needed to drill stone (including granite)? Let's consider the stages of the procedure and preparation for it in more detail.
The working surface on which the stone element will be laid for processing should be not only strong and reliable, but also completely flat, and its dimensions should not be less than the dimensions of the workpiece to be processed. It is very important that none of the parts of the latter remain in weight.
Special tool with integrated coolant supply - a professional approach to natural stone drilling
To successfully drill granite, you need to prepare the following tools and expendable materials:
To diamond drill, with the help of which a hole in the granite will be formed, did not slip off a smooth surface, a depression must first be made at the processing site. For this purpose, you can use a conventional metal drill.
When wondering how to drill granite, it should be borne in mind that it is not easy to carry out such a procedure without using water as a coolant. Cooling of the drill for granite during operation is mandatory, for this purpose it is necessary to supply water to the processing zone.
The simplest device for cooling a stone drill can be made from a plastic bottle by making several small holes in its cap. You will get a kind of spray that is very convenient to use during processing. It should be borne in mind that when drilling, water should always be at hand in order to be able to cool the heated drill at any time.
Having chosen a diamond drill according to the required diameter, which is optimal for drilling in stone (including such hard as granite), the tool must be fixed in the chuck of an electric drill. After that, you can start forming a hole in the workpiece.
An alternative to water cooling - a bit with a grease-like lubricant inside, which flows out when heated into the drilling zone
How to drill a stone so as not to split it, but to form a high-quality hole in it? This question is asked by those who have never encountered the procedure before and are going to do it with their own hands. In such cases, it should always be remembered that the tool used must not be put into punching mode, as the shock load generated may cause the workpiece to split.
Making holes in the stone (including drilling in marble) should be started at low speed of the tool, positioning it at a significant angle. After a small groove has been formed on the work surface, the position of the drill can be gradually leveled.
The drill pressure on the stone during processing should be small, while it is necessary to ensure that the cutting tool does not damage the polished surface of the product. Do not forget that water must be constantly supplied to the drilled section of the hole in which the drill continues to work. Very often, to fulfill such an important condition, a rim is created around the hole being formed from the middle part of a plastic bottle, which is attached to the granite using ordinary tape. Water is poured into the inner part of such a side, the level and presence of which is constantly monitored. It is possible to use this simple device, which prevents not only overheating of the drill, but also the formation of stone dust, only when processing horizontal surfaces.
A stone drill, with which a hole is formed in granite, can be made from a tube made of non-ferrous metal. This method, in comparison with the option in which diamond drills are used, is technically more complicated.
How to properly drill granite with a non-ferrous tube?
Drilling granite using this technique alone is problematic, so you need the help of another person who will make sure that the tub formed around the hole being made is constantly filled with water. Drilling with this technology is also performed at low speeds.
Today we will talk about how to drill a hole in any natural or artificial stone with our own hands at home. We will also consider the methods and technologies for drilling stones or how and how to drill stones yourself
How to drill a hole in the stone yourself and what tool is needed for this?
Now on sale there are drills - diamond-coated crowns and they can be bought in almost any large construction market. The price depends on the thickness of the spray and the service life of the drill.
And if you need to drill one hole and two, then almost any will do. And if you plan to use such a tool frequently, then it is best to purchase a crown in which the diamond is not sprayed, but pressed along the entire volume of the incisal edge.
The attachment of the crown is also different. You can use a drill or grinder. We use heavy cutting machines and a device for drilling holes in stone products, they have the same attachment as a small cutting machine.
And now you have become the owner of a diamond-coated drill, what should you do next?
How to drill a hole in the stone so that it is even and neat?
I think that 4 simple steps will guarantee you long service diamond core bits when drilling holes.
Step 1. When drilling holes in stone, use diamond drills at low speeds (revolutions). Small diamond drills should be used at about 1-2 speeds of your tool - that's about 700 to 1000 rpm.
Diamond drills should be used at varying speeds depending on their diameter.
6mm - 2000 rpm
12mm - 950 rpm
24 mm - 700 rpm
Step 2.
It is necessary to drill holes in stone and other materials with water. Water prevents overheating of the cutting edge of the diamond drill, flushes the cuttings out of its pores. This, in turn, will extend the service life of the drill, protect it from jamming, as well as the stone itself will not overheat and the edge will remain neat.
In production, when drilling holes in a stone, water is automatically supplied to the inside of the drill under pressure and the drill is constantly washed with water. At home, this is not always possible to do.
To do this, you can make a "bath" around the hole to be drilled. You can cut out the middle part from a plastic bottle and glue it with tape to a stone surface, fill it with water. While drilling the holes, lift the bit so that water can wet the cutting edge and enter the hole to be drilled.
Step 3.
If you have little experience, before you start drilling holes in the stone, practice some trimming.
Make the markup. Draw a line on the stone. Often on polishing, a pencil practically does not leave marks, so you can use masking paper tape and make the necessary marks on it.
The first method is often recommended when drilling holes in stone.
First, start drilling the stone at a significant angle to drill a small groove, then gradually flatten the crown until it is upright, while continuing to gently press on it. If you immediately press diamond core bit to the surface of the stone and start drilling, the drill will not stand still but will "roll" over the surface and spoil the polish.
The drills are not always well centered, and if you have little experience in drilling holes in stone, then initially you can not hold the tool and spoil the polish, break the edge of the hole being drilled, and, finally, simply drill inaccurately.
There is a fairly simple second way to drill holes accurately.
To do this, you can drill a hole in any cut of the stone, you can say practice.
Once the hole has been drilled and completely finished, it can be used as a template. Just simply attach to the product in which you need to drill a hole and clamp. Thus, the drill will move along the already drilled hole, it will not be hit and there will be a neatly drilled hole in your product. You can also add water there.
Step 4.
I have already mentioned this, but still decided to highlight it in a separate column.
Do not press hard on the bit while drilling holes. Diamond core bits are very sensitive to pressure and overheating. Lift it up periodically to keep it wet and cool.
Granite is the most difficult material to process. It is a very hard, but at the same time quite fragile stone. Therefore, the work associated with drilling holes in granite must be carried out very carefully and accurately. In order for the granite stone not to split during drilling, it is very important to follow a number of simple rules.
It is imperative to drill granite with water, as it will prevent overheating of the cutting edges of diamond drills, as well as wash out the sludge from its pores. When drilling granite with water, you will thus slightly extend the life of the drill and prevent it from jamming. Also, the granite will not heat up too much when drilling and the edges of the hole will be clear and neat. Nowadays, in production, when drilling holes in stones, water is automatically supplied under pressure to constantly wash the drill.
If you've never drilled granite before, practice on some shard or trim before starting. Before you start drilling granite, make a markup by drawing a line on the surface of the stone. It is best to do this with paper masking tape, since a simple pencil very often does not leave the slightest trace on the polish.
How to drill granite, method one: start drilling granite at a slight angle so that a small groove is drilled first. And then smoothly align the crown to a vertical position. If this is not done, the drill will "ride on the surface".
Drilling in granite, method two: in practice, there are often cases that the drills are poorly or not accurately centered. And if you have no drilling experience, you may not willingly spoil the polishing of the granite, damage the edge of the hole, or drill it completely inaccurately. Therefore, the second method is that you first drill the same hole on a small piece of granite. And if you succeed, then you can now apply it as a template. To do this, you just need to attach it to the desired area of granite and clamp it. The drill will no longer roll over the surface. Water will also need to be supplied there.
How to drill a hole in granite step-by-step instruction.
To drill a hole in granite, you need an electric drill that can be adjusted to the number of revolutions. You will also need a diamond core bit of the required diameter, copper tube or victorious glass, water, a semicircular file, and perhaps you need diamond dust or win.
Before you start drilling, position the granite workpiece as conveniently as possible and secure it. The granite stone must lie completely on a level and flat surface.
Scratch the center of the intended hole with a metal drill. This is important point which will prevent the drill from sliding on the granite surface during operation.
Fix the crown of the required diameter in the electric drill. It must be diamond coated. Otherwise, you will not be able to drill the hole.
Only drill a hole in the granite at low RPM and never turn on the perforation mode. Failure to comply with this condition can provoke granite splitting or cracking.
During the entire process of drilling granite, add water regularly to the hole you are drilling. This can be done using the usual plastic bottle, in which you first need to drill a hole. Perfect option when you bring in a second person to fill up the water so you can concentrate entirely on drilling the granite. It is very important that the drill does not float in the liquid.
Why you need to use water when drilling granite:
· You will not apply unnecessary effort for drilling;
You will save the drill for subsequent work, extending its service life
· You, thus, relieve granite from overheating.
How to drill granite without a diamond core bit.
If you do not have a diamond crown, you can get out of the situation like this: make a plasticine ring around the circumference of the intended hole. Its height should be three to five millimeters. It is necessary to pour a small amount of corundum, diamond dust or win into it. A small tube made of copper or any other non-ferrous metal, such as brass, needs to be fixed into the drill. Then you can start drilling at low speeds and without perforation. Do not forget to supply water during operation, which in this situation will cool the tube.
And if you do not have both a diamond core bit and a non-ferrous metal tube, you can try drilling granite with a victorian drill. But only in this situation, drilling must be carried out immediately at high speeds, constantly supplying water. As soon as you feel that drilling is not taking place, immediately take out the drill and sharpen it with a semicircular file.
Sharpening must be done with extreme care so that the cutting teeth do not overheat under any circumstances. Otherwise, they will immediately become soft, and dull even more quickly. It is noticed that when drilling granite with a drill from a victor, sharpening should be done after every 20-40 seconds of drilling.
As you can see, drilling granite is not an easy task, as it requires certain skills, knowledge and skills. So, when you get to work, be sure to practice on granite scraps, and only then get down to business!
One important part of the laboratory is furniture. Each laboratory in which chemical, biological, medical research will be carried out must have appropriate furniture. Special tables, cabinets, cabinets, tables and cabinets are all an integral part of the laboratory.
For a person who has practically no idea how the process of work in a laboratory takes place, it is completely unclear why regular table or the chair is not suitable for this. But in fact, furniture plays a huge role in the laboratory, which is why household furniture cannot be in the laboratory.
The most basic rule for laboratory furniture is that it must be ergonomic and practical. Experiments and investigations of a different nature should be carried out in a comfortable and well-planned environment. Different decor in such rooms is categorically unacceptable.
The second rule says that a table or some kind of cabinet, whether it is retractable or not, should be simple and multifunctional. For any business, there must be certain furniture that will be responsible for a particular task. For example, an oven must be used only for drying.
The third rule is: laboratory furniture in Moscow must be very durable, since it has to withstand not simple loads. The strength of such furniture should be the highest level as a rule, laboratory furniture must be crack-resistant. Often, such furniture is made from durable material such as plastic, metal or glass.
Innogen LLC is engaged in the sale and production of laboratory furniture. Today, the production of this company is in high demand in all CIS countries. Production room located on the territory Russian Federation, namely in the city of Pskov.
For the production of laboratory furniture, only high-quality and durable equipment for metal processing and painting is used. It must be said that the laboratory furniture of the "Expert" brand has received a quality mark, and is also fully certified in accordance with all the requirements of GOST in Russia.

Drilling of granite must be carried out at low revs (speeds) of the drill. Small diamond-coated drills should be operated at first speed, maximum at second speed. It is important to note the fact that the drills are used at variable speeds depending on their diameter. So if you use a drill with a diameter of six millimeters, you need to work at two thousand revolutions, if the drill diameter reaches 12 mm, then you need to set nine hundred and fifty revolutions on the device, and if you use a drill with a diameter of twenty-four millimeters, then you need to work at speed seven hundred revolutions per minute.

Many builders and just people are wondering how to drill a stone, the answer to it is quite simple, you need to do this with the help of a special drill, at the end of which there are specially equipped solders, the metal of which is very strong and stable.
Most often, this kind of drill is very densely used in order to drill concrete, it is an indispensable find on large construction sites, and in order for the whole process to take place more easily and quickly, a perforator is used for the drill, with which you do not have to apply unnecessary physical efforts , the rock drill itself acts with a strong impact force, which acts on the drill shaft.
All this can be explained by production technology. On the market today you can find a rich assortment of these products in different modifications, it all depends on the wishes of the customer, because manufacturers can make a product in any version. This takes into account criteria such as loads, scope, etc. Such welded metal beams https://bzmto.ru/prodaga-svarnoy-balki can perform the task of a support column, a span in structures, or be a fastening skeleton of a building. Thus, the design can be called universal and multifunctional without any problems.
In order to drill an artificial stone, you need a perforator and special drills that are diamond-coated, this combination allows the tool not to heat up, but at the same time drill holes much faster and without delays, that is, the whole process goes very quickly.
Also, in order to drill a hole in an artificial stone, you can use a diamond drill in combination with a conventional electronic drill, which is available in the arsenal of every owner. In order to make a hole in a small stone, you can use a specially made needle, which has a diamond tip, thanks to it you can make any decoration from a stone in a short time, and an equipped machine can be used as a tool.
In cases where a large-diameter hole is needed, a bit is used, which, like the drill, has at its end solders from a very strong and hard metal alloy. If we talk about the field of application of such a drill, then the main industry is construction, they make holes in large and thick load-bearing walls, such holes are most often needed in order to carry out a ventilation or plumbing pipeline, only with the help of a crown a huge number of holes can be made and at the same time not damage the wall around, which is very important, because in case of damage, additional putty and plastering work will have to be done.
If we talk directly about drilling with a crown, then this should be done at the lowest possible speed, while the tips must be constantly watered with water, this is mandatory if you do not want the crown to overheat, which can subsequently lead to breakage of the entire tool as a whole , as well as to ensure that the service life of the crown is as long as possible.
How to drill an artificial stone, namely a list of tools that are needed for this process:
To do large holes in stones, it is advisable to have equipment available that is designed specifically for this type of work, it is attached to a monolithic concrete wall, and this is done in order to make holes for communication pipes, and in order for the crown to remain intact, it is necessary to bring hoses to it, through which water will continuously flow to its soldering.
You need to understand that in order to drill a stone of equipment is not enough, for this you also need to know a certain technology that is used in this process, and it lies in the fact that each stone has its own strength and hardness and you need to use it for processing and drilling various nozzles, for example, in order to drill granite, which is very hard, but at the same time, it is quite fragile, you need to choose the right drill and decide how thick the hole should be and how deep, the principle is, the thicker the hole should be, the less tool revolutions , and the thinner, the faster they should be.
In order to make a hole exactly in the designated place, you need to tilt the drill to the side and make a groove, which in turn will be able to direct the drill in the desired direction. If we talk about water in this process, then it serves not only so that the soldering does not overheat, but also so that all the debris that forms from drilling is washed out and does not interfere with further penetration.
As for granite and other fragile stones, they are best drilled with a drill, and not with a perforator, since it can crack from constant blows, which will turn out to be an unpleasant and unnecessary moment, because the cost of high-quality granite is not so small. After all the above, the question of how to drill a stone, and also how to drill a stone will fade into the background, because all the most important and necessary things have been said in this article, it will be enough just to use these tips and perform as accurately as possible.

Sometimes such situations arise when working with stones, when it is necessary to make a hole. Of course, when you have at hand necessary equipment it is much easier to do this and does not cause any inconvenience at all. Unfortunately, such equipment may not be at hand at the right time, and this hole is so necessary. For this case, you can use the advice provided and do it yourself.
Choice of tools
First, you need to choose special equipment in order to make a hole in the stone. In this case, a diamond drill is the best choice. It is important to remember that a classic drill, which has a victorious tip, is not suitable for such purposes, but they are sold at every step in the construction market. At the same time, the drilling quality will be at the lowest level. In addition, such equipment can even ruin the work, and the required hole will not be made. Using such a tool, it quickly burns out and breaks the edge, and this is not a feasible result and a good option.
Diamond drill
Today, diamond drills are provided on the world market that are able to cope with such a task without any problems. Such a tool also has another name - a diamond core bit. Using such equipment, you can make a hole in the stone of any diameter that the master needs.
Why is a drill called a diamond drill? This is due to the fact that the tip has a diamond coating. It is because of him that the work is greatly facilitated, while making the hole clean and even. As for the cost, it will depend on the thickness of the spray, as well as the service life of the drill.
Any diamond bit can be used to make multiple holes, although there are exceptions. For frequent use of the tool, it is best to purchase a drill that was made by heat sintering. This method implies a rigid bond between the drill body and the granules. Such a tool is a significantly higher resource when compared with crowns, the manufacturing method of which is diamond sputtering.
The tool also differs in the way the crown is attached to the tool. Mounting is made both on a grinder and on a drill, unless of course there is a tail with an external thread and an internal M14. Mounting is carried out on a special installation that produces diamond drilling.
After the tool has been selected, you need to start drilling a hole in the stone. But in order for the hole to be neat and even, it is necessary to use well-developed techniques.
Hole drilling technique
In order to drill a hole in the stone, you must use water. This action is necessary because the water cools the cutting edge, thereby preventing it from overheating. Thus, the diamond drill will work much longer, and all sludge will be washed out of the spores. In this case, the edge will not jam, and the stone will not overheat during drilling, which is guaranteed, will give a neat and clean edge.
For example, companies that process stones have special installations. Diamond drilling is done automatically, as well as water supply. This happens through the inside of the device. In this way, the edge is constantly cooled and the drill is cleaned. When drilling at home, you can organize a bath that will be located around the hole, and thereby simultaneously cool the edge. So when drilling, you only need to raise the tool so that water constantly gets into the hole and the edges of the drill.
When punching holes in the stone, it is best to set the tool speed to the lowest. Drill small size which are manufactured using diamond spraying technology, when drilling, they should operate at a speed of approximately 700 to 1000 revolutions per minute.
For example, the crowns, which were made using thermal sintering technology, operate at a speed that is constantly changing, depending on the diameter. So for hole diameters:
At 4 millimeters, the speed should be between 1900 and 2100 rpm;
At 10 millimeters, the speed should be between 900 and 1000 rpm;
At 22 millimeters, the speed should range from 650 to 750 rpm.
Preparing to drill a hole
With minimal or no experience in drilling in stone, it is best to train on some other pruning before starting to work.
The best place to start is to do some markup. Pencils very often become invisible on the stone, so it is best to leave marks with masking paper tape on top of which the marking will be made.
Drilling starts at a significant angle, through which a small groove is drilled. Gradually, you need to align the crown so that it acquires a vertical position, while you should not press hard on it. In the event that you start to press on the diamond drill, while pressing it harder against the stone, the tool will begin to move and ruin the surface.
With a little experience working with a drill, you can spoil the polishing of the stone, since it can be very difficult to hold the tool in your hands. In this case, the edges of the hole are broken, and the drilling is not carried out exactly in the intended place.
One important part of the laboratory is furniture. Each laboratory in which chemical, biological, medical research will be carried out must have appropriate furniture. Special tables, cabinets, cabinets, tables and cabinets are all an integral part of the laboratory.
For a person who has practically no idea how the process of working in a laboratory takes place, it is completely incomprehensible why an ordinary table or chair is not suitable for this. But in fact, furniture plays a huge role in the laboratory, which is why household furniture cannot be in the laboratory.
The most basic rule for laboratory furniture is that it must be ergonomic and practical. Experiments and investigations of a different nature should be carried out in a comfortable and well-planned environment. Different decor in such rooms is categorically unacceptable.
The second rule says that a table or some kind of cabinet, whether it is retractable or not, should be simple and multifunctional. For any business, there must be certain furniture that will be responsible for a particular task. For example, an oven must be used only for drying.
The third rule is: laboratory furniture in moscow must be very durable, since it has to withstand not simple loads. The strength of such furniture must be at the highest level, as a rule, laboratory furniture must be resistant to cracking. These furniture are often made from durable materials such as plastic, metal or glass.
Innogen LLC is engaged in the sale and production of laboratory furniture. Today, the production of this company is in high demand in all CIS countries. The production facility is located on the territory of the Russian Federation, namely in the city of Pskov.
For the production of laboratory furniture, only high-quality and durable equipment for metal processing and painting is used. It must be said that the laboratory furniture of the "Expert" brand has received a quality mark, and is also fully certified in accordance with all the requirements of GOST in Russia.
