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

For drilling artificial stone, a perforator and small diamond-coated drills are used.

At the same time, the drill almost does not heat up, and drilling holes is much faster.

Artificial stone can be drilled with a diamond-coated drill. Here you can use a conventional electric drill. 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 diameter hole is required, an artificial drill is drilled with a crown. The crown, like the drill, has soldering of hard alloy. 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. Drilling material with a crown, which has a large diameter, is necessary only at low speeds. During drilling, cold water must be supplied to the carbide tips of the crown. This is necessary so that the soldering does not overheat. Otherwise, they will fail ahead of time.

The main tools for drilling stone are:

drill with carbide tips;
serlo with diamond coating;
crown with carbide tips;
perforator;
diamond-tipped needles;
drill.

In the event that it is necessary to drill holes of large diameter in stones, special equipment is used. So, in order to drill them under communication pipes, such equipment is mounted on a monolithic concrete wall. To prevent stone from damaging the working surface of the crown, cold water is supplied to it with the help of 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 a very hard and at the same time very brittle stone. When choosing the rotational speed of the tool, you must 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, flushes out the sludge. Before drilling, in order to get the hole in the right place, it is necessary to tilt the rotating drill to make a small groove. After that, 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 out of the given point.

The drill must be well centered to avoid damage to the hole edges. The object to be drilled must be on a flat surface and well fixed. Unlike concrete, it is undesirable to drill granite in perforation mode. It is very brittle and can shatter under impact.

When drilling granite, you should proceed from the following parameters of the hole diameter and the speed of rotation 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. Such a need arises when a countertop is made from a relatively thin sheet of granite. A large load on the table surface can break it. To increase the strength of the granite slab, it is reinforced with a steel bar.

An even groove is made on the inner surface of the plate 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 granite reinforced slab will be increased several times. This has also been established empirically.

Almost every day is drilling holes in stone. And it does not cause any particular difficulties when using special equipment. But what to do if you do not have experience and knowledge, but drilling a hole is necessary.
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 on drills with a Pobedite tip, 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 in this hardware store burned out, beat the edge of the hole being drilled, and if these holes were not technical, then it would take a long time to fix the problem.
So. How to drill a hole in a stone on your own and is it necessary for this?

Now drills have appeared on sale - diamond-coated crowns and they can be bought in 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 and two, then almost any will do. And if you plan to use such a tool often, then it is best to purchase a crown in which the diamond is not sprayed, but is pressed over the entire volume of the cutting edge.
Crown fastening is also different. You can use a drill or grinder. We use heavy cutters and a device for drilling holes in stone products, they have the same attachment as on a small cutter.
And now you have become the owner of a diamond-coated drill, what to do next?
How drill a hole in stone so that it is even and neat?

I think that 4 simple steps will guarantee you a long service life of diamond hole saws.

Step 1. When drilling holes in stone, use diamond drills at low speeds (rpm). Small diamond drill bits should be used at about 1-2 speeds of your tool - that's about 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 need with water. Water prevents overheating of the cutting edge of the diamond drill, washes away the 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. doing so is not always possible. 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 to be drilled.

Step 3.
If you have little experience, before you start drilling holes in the stone, practice on some pruning.
Make a markup. Draw a line on the stone. Often, the pencil leaves practically no traces on polishing, so you can use masking paper tape and make the necessary marks on it.
First way which is often recommended for drilling holes in stone.
First, start drilling the stone at a significant angle to drill a small groove, then gradually level the bit until it is vertical, while continuing to lightly press on it. If you immediately press the diamond bit to the surface of the stone and start drilling, then the drill will not stand still, but will “roll” on the surface and spoil it.
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, just drill inaccurately.
There is a pretty simple second way for precise drilling of holes.
To do this, you can drill a hole in any pruning of a stone, you can say to 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 need to drill a hole and clamp. Thus, 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 crown while drilling holes. Diamond coated crowns are very sensitive to pressure and heat. Raise it periodically so that it is moistened with water and cooled.

Be patient and diamond drill bits will last you much longer. Good luck!

Check out my Master Class "How to Drill Stone":

Stones are often used to create various decorations and crafts. In the manufacture of any product, it often becomes necessary to properly drill a hole in a natural material. To do this at home is not entirely simple, but with some knowledge it is quite possible.

A hole in the stone is easy and simple to make using ultrasonic drilling. For this, a special device is used, which costs a lot of money. Therefore, at home, it is better to use simple methods.

In soft stones such as malachite or lapis lazuli, a round opening can be made with a good quality metal drill. For drilling use a special jewelry drill. A hole is made in a stone placed in water. You can simply moisten the material and tool constantly to prevent overheating.

For a through hole, the processed rock must be placed on another stone. To prevent slipping, two materials can be glued or fixed with tape.

It is quite difficult to drill hard stones with high quality. To work, you will need a special tubular drill with a diamond coating. On sale you can find such a tool with a diameter of 1 to 15 millimeters. The most versatile is the size of 2 - 2.5 millimeters.

Execution technique

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

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

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

If a perfectly 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 back.

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

Sometimes there are situations when working with stones when it is necessary to make a hole. Of course, when you have the necessary equipment 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, but this hole is so necessary. For this case, you can use the tips provided and do it yourself.

Tool selection

First you need to choose special equipment in order to make a hole in the stone. In this case, a diamond drill is best. It is important to remember that a classic drill that has a winning tip is not suitable for such purposes, but they are sold at every turn in the construction market. In this case, the quality of drilling will be at the lowest level. In addition, such equipment can even spoil the work, and the necessary hole will not be made. Using such a tool, it quickly burns out and breaks the edge, and this is not a workable result and a good option.

diamond drill

Today, diamond drill bits 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 crown. Using such equipment, it is possible to 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 coating, as well as the life of the drill.

Any diamond hole saw 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 has been made through thermal sintering. This method implies a rigid bond between the body of the drill and the granules. Such a tool is a much higher resource when compared with crowns, the manufacturing technique of which is diamond spraying.

The tool also differs in the way the crown is attached to the tool. Mounting is carried out both on the grinder and on the drill, unless of course there is a tail with an external thread and an internal M14. Fastening is carried out on a special installation producing 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 need to 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 the slimes 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 to give a neat and clean edge.

For example, in companies that process stones, there are special installations. Diamond drilling is done automatically, as well as water supply. This happens through the inside of the device. Thus, there is a constant cooling of the edge and cleaning of the drill. When drilling at home, you can organize a bath that will be around the hole, and thus at the same time will cool the edge. So when drilling, you only need to raise the tool so that water constantly gets into the hole and onto the edges of the drill.

When making holes in stone, it is best to set the tool to the lowest possible speed. Small size drills, which are made using diamond coating technology, should be operated at a speed of approximately 700 to 1000 revolutions per minute when drilling.

For example, crowns that were made using thermosintering technology operate at a speed that is constantly changing, depending on the diameter. Thus, for hole diameters:

At 4 millimeters, the speed should be from 1900 to 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 little or no stone drilling experience, it is best to practice on some other piece of cut before starting work.

The best place to start is to markup. Pencils very often become invisible on the stone, so it is best to leave marks with masking paper tape on top of which 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 put much pressure on it. In the event that you start to put pressure on the diamond drill, while pressing it harder against the stone, the tool will begin to move and ruin the surface.

With little experience 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 drilling is not carried out exactly in the intended place.

What should be laboratory furniture?

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

For a person who has practically no idea how the work process in the 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 laboratory furniture?

The most basic rule for laboratory furniture is that it should be ergonomic and practical. Conducting experiments and research of a different nature 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 any 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, a drying cabinet must be used only for drying.

The third rule is: laboratory furniture in Moscow must be very strong, as it will have to withstand not simple loads. The strength of such furniture should be at the highest level, as a rule, laboratory furniture should be resistant to cracking. Often such furniture is made of durable material, such as plastic, metal or glass.

Where to buy laboratory furniture at affordable prices?

LLC "Innogen" 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, as well as its painting, is used. It must be said that the laboratory furniture of the brand "Expert" received a quality mark, and is also fully certified according to all the requirements of GOST in Russia.

Step 1. When drilling holes in stone, use diamond drills at low speeds (revs). Small diamond drill bits should be used at about 1-2 speeds of your tool - that's about 700 to 1000 rpm.

Do not press hard on the bit while drilling holes. Diamond coated crowns are very sensitive to pressure and heat. Raise it periodically so that it is moistened with water and cooled.

Granite is the most difficult material to process. It is 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 crack during drilling, it is very important to follow a number of simple rules.

A few mandatory recommendations for drilling granite.
Drilling of granite should be carried out at low speeds (speeds) of the drill. Small drills coated with diamond should be operated at the first, maximum - at the second speed. It is important to note the fact that the drills are used at a variable speed 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 diameter of the drill reaches 12 mm, then you need to set the device to nine hundred and fifty revolutions, and if you use a drill that is twenty-four millimeters in diameter, 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, as well as wash the sludge out of its pores. When drilling granite with water, you thus slightly extend the life of the drill and protect it from jamming. Also, when drilling, granite will not heat up too much and the edges of the hole will be clear and neat. Currently, in production, when drilling holes in stones, water is automatically supplied under pressure to constantly wash the drill.

If you have never drilled granite before, then before you start, practice on some fragment or trim. 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 commonly used:

How to drill granite, method one: start drilling granite at a slight angle so that a small groove is first drilled. And then smoothly align the crown to a vertical position. If this is not done, then the drill will "ride on the surface."
Granite drilling, second method: in practice, there are often cases when drills are poorly or not accurately centered. And if you don't have any drilling experience, you can unwittingly ruin the polish 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 succeeded, 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. Now the drill will not roll on the surface. This is where water will need to be supplied.

How to drill a hole in granite, step by step instructions.
To drill a hole in granite, you will need an electric drill with adjustable speed. You will also need a diamond crown of the required diameter, a copper tube or Pobedit glass, water, a semicircular file, and you may need diamond dust or Pobedit.

Before you start drilling, set the granite blank as comfortably as possible and fix it. Granite stone must lie completely on a flat and even surface.
Scratch the center of the intended hole with a metal drill. This is an important point that will prevent the drill from sliding on the granite surface during operation.
Fix the crown of the desired diameter in the electric drill. It must be coated with a diamond coating. Otherwise, you will not be able to drill a hole.
Drill a hole in granite only at low speed and in no case turn on the punching mode. Failure to comply with this condition may provoke a split of granite or the appearance of cracks.

During the entire process of drilling granite into the hole you are drilling, add water regularly. This can be done using an ordinary plastic bottle, in which you first need to drill a hole. Ideal when you involve a second person to add water, so that you can fully concentrate on only drilling 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 apply excessive force for drilling;

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

· you, thus, relieve granite from overheating.

How to drill granite if there is no 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. Inside it is necessary to fill in a small amount of corundum, diamond dust or win. In the drill, you need to fix a small tube made of copper or any other non-ferrous metal, such as brass. After that, 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 granite with a Pobedite 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 semi-circular needle file.

Grinding must be done with extreme caution so that the cutting teeth do not overheat in any case. Otherwise, they will immediately become soft, and will become dull even more quickly. It has been noted that when drilling granite with a drill from a Pobedit, 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, getting started, be sure to practice on scraps of granite, and only then get down to business!
