A hole in the stone at home. How to make a through hole in a stone? Where to buy laboratory furniture at affordable prices

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.

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 to do next?
How to drill a hole in a stone so that it is even and neat?

I think 4 simple steps will guarantee you a long service life for your diamond core bits when drilling holes.

Step 1. When drilling holes in stone, use diamond drills at low speeds (revs). 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.
Drilling holes in stone and other materials must be done 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 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, practice some trimming before you start drilling holes in the stone.

Make the markup. Draw a line on the stone. Often on polishing, the 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 the diamond 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.

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.

After the hole is drilled and completely finished, it can be used as a template. Just simply attach to the product in which you want 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 already mentioned this, but still decided to highlight it in a separate column.
Do not apply too much pressure to the bit while drilling holes. Diamond core bits are very sensitive to pressure and overheating. Lift it up periodically to keep it wet with water and cool.

Granite is the most difficult material to process. It is a very hard, but at the same time quite fragile stone. Therefore, work related to 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.

Currently, the most commonly used two methods of drilling granite:

How to drill granite, method one: start drilling granite at a slight angle so that a small groove is drilled first. After that, 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 experience in drilling, you may not willingly spoil the polishing of 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 \u200b\u200bgranite 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 instructions.
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 bit of the required diameter, a copper tube or victor glass, water, a semicircular file, and perhaps you will need diamond dust or win.

During the entire process of drilling granite, add water regularly to the hole you are drilling. This can be done using a regular plastic bottle, in which you first need to drill a hole. Ideal 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 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 inside 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 victorious 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 will become dull even more quickly. It is noticed that when drilling granite with a drill from a victor, sharpening should be done 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!

Sometimes such situations arise when working with stones, when it is necessary to make a hole. Of course, when the necessary equipment is at hand, 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 best suited. 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 bit. Using such equipment, you can make a hole in the stone of any diameter that the master needs.

Why is the drill called diamond? 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 significantly higher resource when compared with bits, the method of manufacturing them - it is a diamond plating.

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. At the same time, 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 performed automatically, as well as water supply. This happens through the interior of the device. Thus, 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. Small drills, which are made with diamond-coated technology, should operate at speeds between approximately 700 and 1000 rpm when drilling.

For example, the crowns, which were made using thermal sintering technology, operate at a speed that constantly changes, which depends on the diameter. Thus, 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 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 harder against the stone, the tool will move and ruin the surface.

With a little experience with a drill, you can ruin 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.

What should be laboratory furniture?

Furniture is one important part of the laboratory. Each laboratory in which chemical, biological, medical research will be carried out must have appropriate furniture. Special tables, cabinets, cabinets, desks 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 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.

What are the basic rules for furniture in the laboratory?

The most basic rule for laboratory furniture is that it must be ergonomic and practical. Experiments and research of various kinds 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 this or that 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.

Where to buy laboratory furniture at affordable prices?

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 received a quality mark and is also fully certified in accordance with all the requirements of GOST in Russia.

Almost every day has drill holes in stone... And this does not cause any particular difficulties when using special equipment. But what to do if you do not have experience and knowledge, and it is necessary to drill a hole.
I myself remember the first time I went to a hardware store and asked for help from a sales assistant. I needed to drill 2 small holes in a granite slab. The salesperson advised me of the victor tipped drills, assuring me that they fit perfectly.
Without going into details of my first drilling holes in stone, I will only say that 3 drills that I purchased from this hardware store burned out, broke the edge of the hole being drilled, and if these holes were not technical, it would take a long time to fix the problem.
So. How to drill a hole in the stone yourself and is it necessary 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 frequently use such a tool, then it is best to purchase a crown in which the diamond is not sprayed, but pressed throughout 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.

Check out my Master Class "How to drill a stone":

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.

Features of drilling granite

What is needed to drill stone (including granite)? Let's consider the stages of the procedure and preparation for it in more detail.

Workplace preparation

The working surface on which the stone element will be laid for processing must 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

Tools and supplies

To successfully drill granite, you need to prepare the following tools and consumables:

electric drill;
a drill bit of the required diameter, on the working part of which diamond spraying is applied;
water.

To prevent the diamond drill, with which a hole will be formed in the granite, from slipping off the smooth surface, a recess must first be made at the processing site. For this purpose, you can use a conventional metal drill.

What is water for?

When wondering how to drill granite, keep in mind that it is not easy to perform this procedure without using water as a cooling liquid. Cooling of the drill for granite during operation is mandatory; for this, 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 is drilling done

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 themselves. In such cases, it should always be remembered that the tool used must not be placed in 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, placing it at a significant angle. Once a small groove has been formed on the work surface, the drill position 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 to be 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.

How else can you form a hole in granite?

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?

Around the center of the future hole on the granite surface, it is necessary to form a side with a height of at least 5 mm, for which you can use ordinary plasticine or the middle part of a plastic bottle.
It is necessary to pour diamond dust, corundum or victory powder into the inside of the formed rim.
Water is poured into a rim-shaped tray filled with abrasive powder. In order to constantly replenish the water level in such a bath, it is necessary to prepare a separate vessel in which it will be contained in sufficient quantity.

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.

In this article we will take a look at drills that are designed to work with ceramics, brick and stone. Let's analyze the features of working with these materials, operating modes and the main differences between these drills.

Drill for ceramics

Ceramics, in itself, is a moody material. Basically, diamond drills are used for processing. The diamond drill can be manufactured in three different ways. Now we will understand a little about these very methods.

The first way - using the galvanic method, you can make a thin element. The main difference between this method and others is its low cost.

The second is by using powder metallurgy to create stronger tools. These tools will be stable and durable. But the cost will be higher.

The third method is to use the vacuum method to produce a tool that will be characterized by greater strength and increased abrasiveness. The cost of the drill will be inexpensive, and, by the way, it will not be difficult to work with it.

To determine the quality of the drill, it is enough to visually inspect the drill and find out if it has any information about the alloy, diameter, length. This information characterizes mainly expensive products. On cheap drills, such information may not be indicated,

To drill into ceramics, it is necessary to resort to the use of rotation, without vibration.

Before drilling, mark the place where the hole will be drilled. This mark is made using a diamond center punch. Scratching the mark occurs as a result of rotating the center punch until a hole is obtained, the diameter of which is larger than the diameter of the centering rod of the drill. Next, using a thin concrete drill, you need to make a hole that will be centering. Next, you need to drill a hole of the required diameter. Turns - maximum, without using strong pressure. The workplace must be constantly cooled with water.

The approximate cost is from 200 rubles per drill and above.

Brick drill

Using a special carbide drill, you can get a hole in the brick. Now let's talk a little more about this drill.

This drill is usually made of solid steel, respectively. Namely - VK8, in other words, use "win". Such a drill must also have a sharpening for an impact drill, the shape of the shank must be cylindrical. As already became clear, a drill with a blow function is used for drilling.

Drills can be sized from 4 to 12 millimeters. May have a maximum length of 400 millimeters. The drill is not capable of drilling a larger diameter, since it has a slight impact. The cost of the drill is different, from 50 rubles and above.

Drill for stone

So, for drilling a stone, you can use drills with diamond-coated crowns. The cost for such a drill will be different - the thickness of the spraying and the service life of the drill will play a role.

If you need to drill only a couple of holes, then any drill can be used. But if, nevertheless, constant use of the drill is planned, then it is better to buy this tool with a crown, where the entire cutting edge has a pressed diamond.

The crown can be attached in different ways. Usually they use a drill or grinder.

There are a few simple rules to follow to get a clean, clean hole. Namely:

First. A diamond drill involves drilling at low speeds when drilling a hole in a stone. This is usually from 700 to 1000 rpm.

Here are some dependencies of diameters and drilling speeds:

6mm - 2000 rpm;

12 mm - 950 rpm;

24 mm - 700 rpm.

Second. When drilling in stone, use water. This is to prevent overheating of the tool cutting edge. This, incidentally, will serve to extend the life of the drill.

Third. If you do not have enough experience with stone, it is recommended that you practice some kind of trimming before you start drilling holes in the stone.

Fourth. It is not necessary to press hard on the bit during drilling. Diamond core bits are very sensitive to overheating and pressure.

As we have seen, special requirements are put forward for drilling the listed materials, special drills are used. And therefore, when working with such materials, it is necessary to follow the rules for processing the material.

How to make a hole in a stone

Over the past six months, I have probably answered the question of how to make holes in stones a dozen times. I decided to systematize a little and once again, in general terms, tell - now without any individualism.

There is a very simple way - by ultrasound, but not everyone has the device, the ringing from it is worth it, radiates, harmful and does not bring pleasure - however, it works wonders quickly and in skillful hands. But we won't even think about him, we are in the old fashioned way :)

In relatively soft and not fragile stones - such as malachite, serpentine, lapis lazuli - you can make a hole just with a good drill for metal - clamp the drill into a drill, put a pebble in the water - fix it if possible - and go ahead. You can just keep the sponge wet next to the hole - the main thing is not to overheat.

If the hole is through, be sure to put it on another stone, it is even better to glue it with wax or paraffin, but at least with double-sided tape. Otherwise, there will be a chip at the exit.

With harder stones, the story is more complicated. Here you will already need a tubular, diamond-coated drill. They are sold in special stores, such as "Saphira" and in ordinary good household stores, and much cheaper. Their diameters are from 1-1.5 millimeters to 12-15, more is very rare and very specific. I have the most popular 2-2.5 mm.

I cut such drills right away - I cut off the shank a little - then the drill is clamped deeper and does not hit, and this is very important.

We take a stone, figure out why we need it, choose a place, put a mark, glue the bottom with a plaster and put it in a bowl of water. There will be enough water two or three millimeters above the stone. The plaster will help the stone not slip in the bowl and will at least slightly protect it from chipping at the exit of the drill.

And we start at low speeds, slowly, but confidently, to press down the drill in the right place. It is very important not to skew it. Every 15-20 seconds, the drill should be lifted - sludge is removed from the hole. After a few minutes, a groove is formed and the drill is already guided.

The drill gets dull pretty quickly, and does not even get dull - it becomes "greasy", but it is very easy to solve - just put a piece of ordinary emery next to the stone and touch it with a drill from time to time.

When the drill goes a few millimeters deep into the stone, it is desirable to break the core column that has formed with a pin, scribe, iron and shake it out - then it is a little more difficult to knock it out of the drill, although it is also not a problem.

When the hole tends to exit, you can start drilling from the other side, but this is only when increased demands are made on the quality of the hole.

A little more and the drill will go easily - it has come out, which means, to the surface, which is what we need.

That's, by and large, that's all.

In this case, a 4 mm cabochon was drilled in about a quarter of an hour, but this drill has already made more than a dozen holes in agates and flints, the new one works faster.

On paper (on the screen) everything is quick and easy, in reality it is a little more complicated, and not even more difficult - you need to be prepared for what will start to work out normally somewhere in the fifth, sixth.

I would also like to draw your attention to the following points - the drill is quite soft, its walls are thin, it should be clamped extremely gently into the chuck. When you put aside the tip with a clamped drill, so that it does not cling to anything, it bends instantly and practically does not straighten to its normal state. After work, be sure to immediately clean it from the inside, otherwise the sludge will dry out and there will be problems in the future. It is also better to drill soft stones with such drills - neat and dignified. You can also drill with an ordinary drill - it is better to put it on its side, and constantly dipping a pebble under the drill. And remember the rules for working with electrical appliances!

It seems that you can finish with this about the holes :)

And about this agate one of these days I will try to continue.

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 the diamond 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.

Drills are not always well centered, and if you have little experience in drilling holes in stone, then initially you may 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 method for accurately drilling holes To do this, you can drill a hole in any cut of the stone, you can say practice. After the hole is drilled and completely ready, 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 already mentioned this, but nevertheless decided to highlight it in a separate column. Do not press hard on the crown while drilling holes. Diamond core bits are very sensitive to pressure and overheating. Lift it up periodically to keep it wet and cool.

Several must-have recommendations for drilling granite. Drilling of granite should 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. 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 somewhat 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 the granite, mark it 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.

Currently, two methods of drilling granite are most commonly used: How to drill granite, method one: start drilling granite at a slight angle so that a small groove is drilled first. After that, 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 experience in drilling, you may not willingly spoil the polishing of 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 \u200b\u200bgranite and clamp it. The drill will no longer roll over the surface. You will also need to supply water there. Step by step instructions on how to drill a hole in granite.

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 bit of the required diameter, a copper tube or victor glass, water, a semicircular file, and perhaps you will need diamond dust or win.

Before you start drilling, position the granite workpiece as conveniently as possible and secure. The granite stone must lie completely on a flat and level surface. Scratch the center of the intended hole with a metal drill. This is an important point to prevent the drill from sliding over 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. Drill a hole in the granite only at low RPM and never use 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 a regular plastic bottle, in which a hole must first be drilled. Ideal when you use 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 it is necessary 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, save the 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 inside 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 victorious 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 happening, 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 will dull even more quickly. It is noticed that when drilling granite with a drill from a victor, sharpening should be done 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 down to work, be sure to practice on the granite scraps, and only then get down to business!

It is best to drill artificial stone with a drill, at the end of which there are hard alloy solders. In construction, such drills are used when drilling concrete. To make the work more productive, drilling is done with a hammer drill. Drilling with a hammer drill occurs due to the impact force of the drill.

To drill artificial stone, a perforator and small diamond-coated drills are used.

At the same time, the drill hardly heats up, and the holes are drilled much faster.

Artificial stone can be drilled with a diamond drill. You can use a regular electric drill here. If you need to drill a thin hole, for example in a small natural stone for decoration, a diamond tipped needle is used. This is done on a drilling machine.

If a large hole is required, the artificial drill is drilled with a crown. The bit, like the drill, has hard alloy solders. In construction, such drilling is done in load-bearing concrete walls. This is done in the case when it is necessary to lay plumbing or ventilation pipes. It is necessary to drill the material with a bit, which has a large diameter, only at low speeds. During drilling, cold water is always supplied to the carbide-tipped bits. This is necessary so that the soldering does not overheat. Otherwise, they will fail ahead of schedule.

The main tools for drilling stone are:

Drilling tools: tungsten carbide drill, diamond drill, tungsten carbide crown, hammer drill, diamond tipped needles, drill.

tungsten carbide drill;
serlo with diamond plating;
tungsten carbide crown;
puncher;
diamond tipped needles;
drill.

In the event that you need to drill large holes in stones, special equipment is used. So, in order to drill them for communication pipes, such equipment is mounted on a monolithic concrete wall. To prevent the stone from damaging the working surface of the crown, cold water is supplied to it using hoses.

Drilling technology

The processing of solid materials is associated with the use of a certain technology. Drilling stones has its own specifics. For example, granite is very hard and at the same time very brittle stone. When choosing the rotation speed of the tool, you need to proceed from the diameter of the hole to be drilled. The larger the bore is needed, the less revolutions are required.

To get the hole in the right place, you need to make a small groove by tilting the rotating drill to the side.

During drilling, the water supply must be mandatory. Water, firstly, protects the cutting edges of the diamond drill from overheating, and, secondly, flushes out the cuttings. Before starting drilling, in order to get the hole in the right place, you need to tilt the rotating drill to make a small groove. The drill is then leveled and smooth drilling begins at this point. This is necessary so that at the very beginning the drill does not move off the set point.

The drill must be well centered to avoid damaging the edges of the hole. The object to be drilled must be on a level surface and well fixed. Unlike concrete, it is undesirable to drill granite in perforation mode. It is very fragile and can crack in shock mode.

When drilling granite, one should proceed from the following parameters of the hole diameter and the rotational speed of the drill. With a hole diameter of 6 mm, the rotation speed should be 2000 rpm. With a hole - 12 mm, rotation speed - 950 rpm. If the hole is 24mm, the rotation speed should not exceed - 700 rpm. Such data are obtained empirically and are the most optimal.

In some cases, granite needs to be reinforced. This need arises when a tabletop is made from a relatively thin sheet of granite. A large load on the table surface can break it. To increase the strength of a granite slab, it is reinforced with a steel bar.

An even groove is made on the inner surface of the slab with the help of a grinder and a diamond wheel. The depth and width of the groove should be 1 mm larger than the steel bar. After removing dust from the groove, a steel bar is placed in it. The rod laid in the groove is filled with superglue. After the glue hardens, the strength of the reinforced granite slab will be increased several times. This has also been established empirically.
