One important part of the laboratory is the furniture. Each laboratory in which chemical, biological, and medical research will be carried out must have appropriate furniture. Special tables, cabinets, cabinets, tables and cabinets - all this is an integral part of the laboratory.

For a person who has virtually no idea of how the process of working in a laboratory occurs, it is completely unclear 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 laboratory furniture?

The most basic rule for laboratory furniture is that it should be ergonomic and practical. Conducting experiments and research of various types should be carried out in a convenient 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. Eg, drying cabinet, must be used only for drying.

The third rule is: laboratory furniture in Moscow must be very durable, since it will have to withstand difficult loads. The strength of such furniture should be top level As a rule, laboratory furniture must be resistant to cracks. Often such furniture is made from durable material, 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. 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 laboratory furniture of the Expert brand has received a quality mark and is also fully certified according to all GOST requirements in Russia.

Sverlit kamen. How to drill a hole in any natural or artificial stone yourself at home. Methods and technologies for drilling stones or how and with what to drill stones yourself

Today we will talk about how to drill a hole in any natural or artificial stone with your own hands. We will also consider methods and technologies for drilling stones or how and with what to drill stones yourself

How to drill a hole in a stone yourself and what tool is needed for this?

Diamond-coated drill bits are now available for sale and can be purchased at almost any major construction market. The price depends on the thickness of the coating and the service life of the drill.

The fastening of the crown also varies. 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 mount 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 stone so that it is smooth and neat?

I think that 4 simple steps will guarantee you a long life of diamond bits when drilling holes.

Step 1. When drilling holes in stone, use diamond drills at low speeds (rpm). Small diamond-coated drill bits should be used at approximately 1-2 speed of your tool - this is approximately 700 to 1000 rpm.

Diamond drills must be used at variable speeds depending on their diameter.
6mm – 2000 rpm.
12mm – 950 rpm.
24 mm – 700 rpm.

Step 2.
Drilling holes in stone and other materials requires water. Water prevents overheating of the cutting edge of a diamond drill and washes away sludge from its pores. This, in turn, will extend the life of the drill, protect it from jamming, and the stone itself will not overheat and the edge will remain neat.

In production, when drilling holes in stone, water is supplied automatically to inner part drills are under pressure and the drill is constantly washed with water. It is not always possible to do this at home.

Step 3.
If you have little experience, practice on some trim before you start drilling holes in stone.

Make the markings. Draw a line on the stone. Often the pencil leaves virtually no traces when polishing, 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 level the crown until it is vertical, continuing to apply gentle pressure. 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” along the surface and spoil the polishing.

There is a fairly simple second method for accurately drilling holes.
To do this, you can drill a hole in any piece of stone, you could say practice it.

Once the hole is drilled and completely finished, it can be used as a template. Simply apply it to the product in which you need to drill a hole and clamp it. This way the drill will move along the already drilled hole, it will not hit and your product will have a neatly drilled hole. You can also add water there.

Step 4.
I already mentioned this, but still decided to highlight it in a separate column.
Do not press hard on the bit while drilling holes. Diamond-coated crowns are very sensitive to pressure and overheating. Lift it periodically to wet it with water and cool it.

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 to prevent granite stone from splitting during drilling, it is very important to follow a number of simple rules.

It is necessary to drill granite with water, as it will prevent overheating of the cutting edges of diamond drills, and will also wash away the sludge from its pores. When drilling granite with water, you will thus somewhat extend the life of the drill and protect it from jamming. Also, granite will not heat up too much when drilling and the edges of the hole will be clear and neat. Currently, in production, when drilling holes in stones, water is supplied under pressure automatically to constantly wash the drill.

If you have never drilled granite before, practice on some fragments or cuttings before you begin. Before you start drilling granite, make a marking 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 often used:

How to drill granite, method one: start drilling granite at a slight angle so that a small groove is drilled first. And after that, smoothly align the crown to a vertical position. If this is not done, the drill will “ride along the surface.”
Drilling granite, method two: in practice, there are often cases where the drills are poorly or not accurately aligned. And if you have no drilling experience, you may unwittingly ruin the polish 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 succeeded, then you can now use it as a template. To do this, you just need to attach it to the desired area granite and clamp. Now the drill will not roll on 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 will need an electric drill in which you can adjust the number of revolutions. You will also need diamond crown required diameter, copper tube or pobedit glass, water, a semicircular file, and perhaps you will need diamond dust or pobedit.

Before you start drilling, position the granite workpiece as comfortably as possible and secure it. The granite stone must lie completely on a level and flat surface.
Using a metal drill, scratch the center of the proposed hole. This important point which will prevent the drill from sliding on the granite surface during operation.
Fix a bit of the required diameter in the electric drill. It must be coated with diamond coating. Otherwise you will not be able to drill the hole.
Drill a hole in granite only at low speeds and never turn on the perforation mode. Failure to comply with this condition may cause the granite to split or cracks to appear.

During the entire process of drilling granite, regularly add water to the hole you are drilling. This can be done using a regular plastic bottle, in which you first need to drill a hole. Perfect option, when you involve a second person to add water so that you can fully concentrate only on drilling the granite. It is very important that the drill does not “float” in the liquid.

Why is it necessary to use water when drilling granite:

· you will not put unnecessary effort into drilling;

· you will save the drill for subsequent work, extending its service life

· you will thus save the granite from overheating.

How to drill through granite if you don't have a diamond bit.

If you don’t have a diamond crown, you can get out of the situation like this: make a ring of plasticine around the circumference of the intended hole. Its height should be three to five millimeters. A small amount of corundum, diamond dust or victoria must be poured inside it. You need to attach a small tube made of copper or any other non-ferrous metal, such as brass, to the drill. After this, 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 don’t have both a diamond crown and a non-ferrous metal tube, you can try drilling through granite using a pobedit 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 using a semicircular file.

Grinding must be done with extreme caution so that the cutting teeth do not overheat under any circumstances. Otherwise, they will immediately become soft and become dull even faster. It has been noticed that when drilling granite with a drill from Pobedite, 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 abilities. So, when starting work, be sure to practice on granite scraps, and only after that get down to business!

Execution technique

Before the work process, you should mark the exact location on the stone for the hole. For convenience, a mark is placed in this area. You can make a hole in solid rock yourself using the following technology:

The bottom of the selected container is sealed with adhesive tape. This is necessary so that the stone does not slip in the vessel and chips and cracks do not form when the drill comes out.
After this, water is poured in. It should cover the stone by only three millimeters.
Hard material is drilled at low speeds. This process should be performed smoothly, carefully, but confidently enough. Every 15 - 20 seconds you need to stop processing to remove the resulting sludge.

Within a short time, a notch is formed in the stone. After this, drilling will become easier, since the direction will be set. The tool quickly becomes dull during processing. To preserve its original properties, you can put a segment sandpaper near the stone and periodically touch it with a drill.

If a completely even hole is required, then when it becomes noticeable that the drill is approaching the exit, the stone is turned over and drilled from the other side.

In practice, the first drilling of a hole is not always successful. But with experience the right approach You can create an even through opening of four millimeters in stone in less than an hour. However, it is not necessary to buy a new one for each hole. cutting tool. The main thing is desire and patience.

It is possible to drill a hole in such a durable stone as granite, but it is necessary to thoroughly prepare for this difficult procedure. For drilling, you will need not only a granite drill, but also a set of appropriate tools and accessories. You should also properly prepare your workplace.

Features of drilling granite

What is needed for drilling stone (including granite)? Let us consider the stages of the procedure and preparation for it in more detail.

Preparation of the workplace

The working surface on which to be placed for processing stone element, must not only be strong and reliable, but also completely flat, and its dimensions should not be less than the dimensions of the product being processed. It is very important that no part of the latter remains suspended.

Special tool with built-in coolant supply – a professional approach to drilling natural stone

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, the working part of which is coated with diamond;
water.

So that the diamond drill, which will be used to form a hole in granite, does not slip off smooth surface, a recess must first be made at the treatment site. For this purpose you can use regular drill on metal.

Why is water needed?

When wondering how to drill through granite, you should keep in mind that performing such a procedure without using water as a coolant is not easy. Cooling of the granite drill during operation is mandatory; it is for this purpose that water must be supplied to the processing area.

The simplest device for cooling a drill for stone can be made from a plastic bottle by making several small holes in its lid. You will receive a kind of spray bottle, which 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 selected a diamond drill according to the required diameter, which is optimally suited for drilling stone (including something as hard as granite), the tool must be fixed in the chuck of an electric drill. After this, you can begin to form a hole in the workpiece.

An alternative to water cooling is a bit with a greasy lubricant inside, which flows out into the drilling area when heated.

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 planning to do it themselves. In such cases, you should always remember that the tool you are using cannot be set to hammer mode, since the created shock load can cause the workpiece to split.

Making holes in stone (including drilling marble) should begin at low speeds of the tool, positioning it at a significant angle. After a small groove has been formed on the surface to be treated, the position of the drill can be gradually leveled.

The pressure of the drill on the stone during processing should be light, and care must be taken 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 area of the hole in which the drill continues to work. Very often to do this important condition around the hole being formed, a side is created from the middle part of a plastic bottle, which is attached to the granite using regular tape. Water is poured into the inside of such a side, the level and presence of which is constantly monitored. This simple device, which prevents not only overheating of the drill, but also the formation of stone dust, can only be used when processing horizontal surfaces.

How else can you form a hole in granite?

A stone drill, which is used to form a hole in granite, can be made from a tube made of non-ferrous metal. This method, compared to the option that uses diamond drills, is more technically complex.

How to drill granite correctly using a non-ferrous metal tube?

Around the center of the future hole on the surface of the granite, 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.
Diamond dust, corundum or pobedite powder must be poured into the inner part of the formed side.
Water is poured into a bath formed by the side and 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 quantities.

Drilling granite using this method alone is problematic, so you will need the help of another person who will ensure that the tray formed around the hole is constantly filled with water. Drilling when using this technology is also performed at low speeds.

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

Drill for ceramics

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

The first method is to produce a thin element using the galvanic method. The main difference between this method and others is its low cost.

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

The third way is to use the vacuum method to produce a tool that will be characterized by greater strength and have 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 a 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 ceramics, it is necessary to resort to the use of rotation, without vibration.

Before drilling, you need to mark the location where the hole will be drilled. This mark is made using a diamond punch. Scratching of the mark occurs as a result of rotation of 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 serve as a centering hole. Next, you need to drill a hole of the required diameter. The revolutions are maximum, without using strong pressure. Workplace need to be constantly cooled with water.

approximate cost from 200 rubles per drill and above.

Brick drill

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

Such a drill is usually made of hard steel, respectively. Namely - VK8, in other words, they use “will win”. Such a drill must still have sharpening for impact drill, the shape of the shank should be cylindrical. As has already become clear, a drill with an impact function is used for drilling.

Drills can have sizes from 4 to 12 millimeters. May possess maximum length 400 millimeters. The drill is not capable of drilling a larger diameter, as it has a weak impact. The cost of the drill varies, from 50 rubles and above.

Stone drill

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

If you need to drill just a couple of holes, then you can use any drill. But if, nevertheless, you plan to constantly use the drill, 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 a drill or grinder is used.

To obtain a smooth and neat hole, you must follow several simple rules. Namely:

First. A diamond drill bit involves drilling at low speeds when drilling a hole in 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, you need to use water. This is necessary to prevent overheating of the cutting edge of the tool. This, by the way, will serve to extend the service life of the drill.

Third. If you do not have enough experience working with stone, it is recommended that you practice on some trim before you start drilling holes in stone.

Fourth. There is no need to press hard on the crown while drilling. Diamond-coated crowns are very sensitive to overheating and pressure.

As we have seen, special requirements are put forward for drilling the listed materials, and 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 stone

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

There is a very simple method - ultrasound, but not everyone has the device, it makes a ringing sound, emits, is harmful and does not bring pleasure - however, quickly and in in capable hands works wonders. But we won’t even think about it, we’ll do it the old fashioned way :)

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

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

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

I immediately cut such drills - 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, cover the bottom with a plaster and put it in a bowl of water. Two to three millimeters of water above the stone is enough. The adhesive will help the stone not to slide in the bowl and will at least protect it a little from chipping at the exit of the drill.

And we begin at low speeds, slowly but confidently, pressing the drill into in the right place. It is very important not to distort it. Every 15-20 seconds the drill should be lifted to remove debris from the hole. After a few minutes, a groove is formed - and the drill already receives direction.

The drill gets dull quite quickly, and doesn’t even get dull - it gets “greasy”, but this can be solved very simply - just put a piece of ordinary emery next to the stone and touch it with the drill from time to time.

When the drill goes a few millimeters deep into the stone, it is advisable to break the core column that has formed with a pin, a scriber, or a piece of iron and shake it out - then knocking it out of the drill is a little more difficult, although this 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 placed on the quality of the hole.

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

That, by and large, is all.

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

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

I would like to draw your attention to the following points: the drill is quite soft, its walls are thin, and it must be clamped into the chuck extremely gently. When you put the tip aside with the drill clamped so that it does not cling to anything, it bends instantly and practically does not straighten out until normal condition. 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 - carefully and with dignity. You can also drill with a regular drill - it is better to put it on its side, and constantly dip the pebble under the drill. And remember the rules for working with electrical appliances!

It seems like we can finish here about the holes :)

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

Today we will talk about how to drill a hole in any natural or artificial stone with your own hands at home. We will also consider methods and technologies for drilling stones, or how and with what to drill stones yourself. How to drill a hole in a stone yourself and what tool is needed for this?

Diamond-coated drill bits are now available for sale and can be purchased at almost any major construction market. The price depends on the thickness of the coating and the service life of the drill.

And if you need to drill one hole or 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 into the entire volume of the cutting edge. The fastening of the crown can also be 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 mount as on 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 stone to was it smooth and neat? I think that 4 simple steps will guarantee you a long life of diamond bits when drilling holes.

Diamond drills should be used at variable speeds depending on their diameter. 6mm – 2000 rpm. 12mm – 950 rpm. 24 mm – 700 rpm. Step 2. Drill holes in stone and other materials with water. Water prevents overheating of the cutting edge of a diamond drill and washes away sludge from its pores. This, in turn, will extend the life of the drill, protect it from jamming, and the stone itself will not overheat and the edge will remain neat.

In production, when drilling holes in stone, water is automatically supplied to the inside of the drill under pressure and the drill is constantly washed with water. It is not always possible to do this at home.

To do this, you can make a “bath” around the drilled hole. You can cut out the middle part of a plastic bottle and stick it with tape to a stone surface, fill it with water. When drilling holes, lift the bit so that water wets the cutting edge and enters the hole being drilled. Step 3. If you have little experience, before you start drilling holes in the stone, practice on some scrap material. Make markings. Draw a line on the stone. Often, a pencil leaves virtually no marks on polishing, 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.

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” along the surface and spoil the polishing.

Drills are not always well centered, and if you have little experience in drilling holes in stone, then initially you may not be able to hold the tool and spoil the polishing, 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 piece of stone, you can say practice. After the hole is drilled and completely ready, it can be used as a template. Simply apply it to the product in which you need to drill a hole and clamp it.

I already mentioned this, but I still decided to put it in a separate column. Do not press hard on the crown while drilling holes. Diamond-coated crowns are very sensitive to pressure and overheating. Lift it periodically to wet it with water and cool it.

Several mandatory recommendations for drilling granite. Drilling granite should be carried out at low speeds (speeds) of the drill. Small drills coated with diamond coating should be operated at first, or maximum at second speed. It is important to note the fact that drills are used at variable speeds depending on their diameter. So if you are using a drill with a diameter of six millimeters, you need to work at two thousand revolutions, if the diameter of the drill reaches 12 mm, then you need to set the device to nine hundred and fifty revolutions, and if you are using a drill whose diameter is twenty-four millimeters, then you need to work at speed seven hundred revolutions per minute. It is necessary to drill granite with water, as it will prevent overheating of the cutting edges of diamond drills, and will also wash away the sludge from its pores. When drilling granite with water, you will thus somewhat extend the life of the drill and protect it from jamming. Also, granite will not heat up too much when drilling and the edges of the hole will be clear and neat.

It is best to drill artificial stone using a drill, the end of which has carbide brazing. 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 hammer drill and small diamond-coated drills are used.

At the same time, the drill hardly heats up, and drilling holes is done much faster.

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

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

The main tools for drilling stone are:

Drilling tools: carbide-tipped drill bit, diamond-tipped drill bit, carbide-tipped bit, hammer drill, diamond-tipped needles, drill.

drill with carbide tips;
diamond-coated bit;
crown with carbide tips;
perforator;
diamond tipped needles;
drill.

If you need to drill large diameter holes in stones, use special equipment. 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

Processing of solid materials involves the use of a certain technology. Drilling stones has its own specifics. For example, granite is a very hard and at the same time very fragile stone. When choosing the rotation speed of the tool, you need to proceed from the diameter of the hole being drilled. The larger the diameter of the hole, the lower the required speed.

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, water supply must be mandatory. Water, firstly, protects the cutting edges of the diamond drill from overheating, and, secondly, washes away the sludge. 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. After this, the drill is leveled, and even drilling begins in this place. This is necessary so that at the very beginning the drill does not move from the given point.

To avoid damaging the edges of the hole, the drill must be well centered. The drilling object must be on flat surface and be well fixed. Unlike concrete, drilling granite using perforation mode is not advisable. It is very fragile and can break if subjected to shock.

When drilling granite, you should proceed from following parameters hole diameter and drill rotation speed. 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 was obtained experimentally and is 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 surface of the table can break it. To increase the strength of the granite slab, it is reinforced with steel rod.

On inner surface slabs using a grinder and diamond wheel a smooth groove is made. The depth and width of the groove should be 1 mm larger than the steel rod. After removing dust from the groove, a steel rod is placed in it. The rod placed 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.
