How to cut a hole in protective glass. How to drill a hole in glass - the necessary tools and drilling technology

Glass is a fragile material that is subject to impact and uneven heating, so it has several important properties. Consider drilling technology glass products at home, as well as the tools and devices that need to be used.

Protective glasses

For working with glass, it is best to use special drills (1, 2) and diamond-coated core bits (3, 4) shown in the figure below.

They will create many high quality holes. You can also drill hardened and winning drills (5).

The job will take longer. Use this tool very carefully.

In the hole, make a hole in the glass, which allows even normal drilling in metals (6). To do this, fine wet sand must first be poured into working area and then add it sometimes.

Disadvantages of this method: hard work, spinning tools.

Glass rotates at low speeds: 300 - 700 per minute. Suitable is a manual or electric drill with adjustable speed.

How to drill a hole in home glass: dismantle all options

Radial and axial drilling in the stem should be kept to a minimum. Otherwise, it should be replaced.

drill glass at home

Don't hold the weight without stopping. The glass should be placed on a flat horizontal surface so that it snaps against it. It is not advisable to use a thin soft tissue substrate.

It is convenient to mark the center of the hole with a marker, plug or gel.

It is desirable to remove at least six of its thickness from the edges of the glass. Otherwise, the probability of hacking is high.

During operation, the drilling hole and hole must be constantly wetted with coolant to ensure heat dissipation.

For this purpose, water, kerosene or turpentine are usually used. You can protect the drilling site with a plasticine ring and pour the liquid into the molded tub.

Using a panel like wood panel or plywood with a hole of the required diameter, hold the drill plate. You can use another option - hold the adhesive tape on the glass.

Drilling pressure should be low.

Otherwise, the probability of vitreous cracking increases significantly. As the pressure progresses, the pressure must be reduced. This will help not to collapse too much when exiting the hole.

The resulting sharp edges should be sanded with fine sanding paper.

Tempered glass cannot be drilled

This will split into a number of small fragments, despite the fact that it has increased power. Strained glass often used in the automotive industry, furniture industry, housing construction. It is distinguished by a mark in the form of the letter " with"But the inscription" tempered».

If there are no signs, look for other features. These can be luminous spots that are visible on the surface at a certain angle, as well as with polarizing glasses and filters.

According to GOST R 54162-2010, edges and holes are processed before curing.

Sharp edges indicate that the glass does not glow.

The fragile, capricious and fragile structure of home glass presents a very serious problems with the processing of this substance.

Glass is difficult to cut into platinum, and even more difficult to cut through holes in it. However, sometimes it is necessary to choose the material in the glass canvas. However, if you want to successfully drill glass in a live environment, you need to know some special tricks.

Before you start drilling holes in the glass, you should be ready to go.

Initially, it should be disassembled or removed from the box, if any.

Then you must remove all external decorative elements such as corners, decorative rivets, suction cups and other materials.

Then it is necessary to clean the labels and movements, and then treat the surfaces of the glass plate with fatty substances.

Drill glass can be manual and electric, but experts recommend that the material is selected from the glass cloth with an electric drill.

This recommendation is due to the density of the glass structure, since sampling requires high speeds with a minimum load on the drilled material. The glass sheet during the drilling process must be placed on an absolutely flat smooth surface, the material must be on the working surface, otherwise the glass may simply burst.

Even before drilling glass with any point drills, it is desirable to fix the drilling area.

To do this, place the blade with roller glass in the middle of the future hole, gently press it and turn the tool along its longitudinal axis.

In this way, a small groove is formed on the glass canvas and will not float on the glass surface from the very beginning of drilling. You can also insert a transparent strip in layers 2-3 on the drilling site.

Rotary glass can be traditionally hardened drill, this tool, unlike classic steel drills, has a more durable cutting material, which allows you to slowly and reliably drill a glass structure.

You can buy hardened drill bits from specialty stores and you can also make them individually.

How to make a hole in glass? Here are two easy ways

To harden ordinary steel drills, it is necessary to heat up to an alcohol burner or a conventional stove. The heated battle should then be dipped into a container of sealing wax and cooled. Hardened drilling prior to use directly for turpentine grease. However, the best result is still achieved with special diamond drilling.

You can choose glass material with copper wire or hollow copper tube.

These tools are an alternative to hardened drills and are also used as accessories for electric drilling.

Glass for drilling with thick copper wire is only possible when applied to glass special composition. The working mixture should consist of one part camphor, two parts turpentine and four parts powder.

The prepared composition should be applied to the glass area in which the material will be taken.

Hollow copper tube from drill glass is only possible with corundum powder. To this end, the spindle area must be covered within a radius of two centimeters with a plasticity of one centimeter.

Then corundum powder moistened with water must be poured into the molded cavity, and it can be started to be drilled.

Designing large round holes in glass sheets can hardly be called drilling, since their implementation is based on glass cutting.

First you need to drill a small hole in the middle of the next round. Then the glass should be placed on a flat wooden surface, and a small nail should be pushed through the molded hole in the wooden base.

The nylon thread should be attached to the nail and the glass cut should be attached to the end of the thread at a distance from the future hole radius. The circle must be rubbed at the border of the stretched thread, and then the unnecessary material is pressed with a simple touch. Treat thin sanding paper with a sharp edge.

How to drill glass: three easy ways.

It seems that a hole in glass is impossible, and still impossible in round bottles.
In fact, drilling holes are very simple. You need physical exercise, two plates, ribbon and water.

There are many tools: f.ua/shop/ruchnoj-instrument

How to drill a hole in glass - the necessary tools and drilling technology

Section: "Master of the house"

To drill glass, you will need two things: a glass on the glass and a coolant for the drill bit. For cooling, I mean, I guess.

When drilling glass as well as other materials, a lot of heat is generated, but if it is not shown on other materials, it is important for glass.

Below you will find several types of drills in the photo on glass, some of which can also be drilled in ceramics.

The tallest in the picture is a regular and cheap drill bit, feather-shaped or a carbide-shaped spear.

Diameters from 3 to 13 mm. Drilling quality is satisfactory, small chips are possible.

The second is a letter, but with a diamond coating. It runs smoother than a carbide tip.

The next three exercises - tubular, small diameter or round glass work - are used to cut circles and rings in glass, i.e. holes. It is best for drilling machines, even if you can use hand drill Houses.

They differ in production technology and diameter. Next, from top to bottom, the yellow drill is completely made of brass tube, and finally, the diamond coating is electroplated in two layers.

When drilling holes with such drills, all work must be carried out only by cooling, supplying water or other special coolant to the work surface.

And the lowest in the photodrill is a tubular diamond bolt large diameter.

It is used for drilling holes in glass, ceramics and other non-metal materials. The case is made of steel, in the form of a crown with a stem of 9 mm.

At the end of the crown, the diamond powder was dispersed in various fractions. Drilling, like the previous exercises, should be done by cooling.

If you're spinning it on glass that you didn't have, you can do it yourself - from the side of the old three-axis file.

The mill needs to be cut from a portion of the file on one side of the round edge so it can be squeezed into the holder and the other side to make a pointed drill - 3 pages sharp under a sharp 3 sided wedge with an angle of about 30-40 degrees. It also needs to be adjusted to the desired diameter. During grinding, you must constantly cool the drilling in the water so that you do not let it go.

Drilling with such a drill is best done with a carpenter with an engine speed of 120-150 rpm. When the drill tip passes through the glass, rotate the glass and slowly turn it back. The drilling site should always be moistened with water or turpentine. In order not to spoil the valuable workpiece, first trim the glass.

Now finish the work on the glass, now let's look at home cooling methods.

To ensure that the glass does not break from the temperature difference between drilling, heat must be removed from the drill bit.

In principle, there is nothing complicated, you can easily wet the drilling and drilling site with water over time. Another way is more reliable: it makes a ring from plasticine, it is well applied to the drilling site and pours water into it.

A more advanced way is to attach a faucet to a water faucet, this is possible from a drop, and then put in a glued ring of plates (borders) and thus make a stream of water.

The water will cool down and remove the heat as much as possible.

After all, it must be drilled at low speeds between 250 rpm (maximum drill) to 1000 rpm (smallest drill) and do not put much pressure on it and finally more to relieve pressure. The glass itself, like cutting, must lie on a flat and hard surface.

How to drill glass at home with your own hands

Well, to work with glass, of course, it must be beautiful. Try it and you will succeed!

- the material is extremely fragile and difficult to process at home. However, in some cases the knowledge how to drill glass, might be useful to you. For example, if there is a need to hang glass shelves on the wall, a bathroom mirror or repair a damaged glass table. How to do the right glass repair, this article will tell.

How to drill a hole in glass

Few people know, but you can get an even and neat hole in the glass using the most ordinary drill. However, you will need a fire-hardened drill bit. If this is not at hand, it is necessary to harden an ordinary steel drill. To do this, it must be placed in a flame. gas burner and keep until red. After heating, the drill is placed in a container with sealing wax, where it cools. After this procedure, such a drill can be used to create holes in the glass. It is recommended to moisten the tip of the drill with turpentine before drilling. Also, do not forget that all work must be carried out only with the strictest observance of safety rules. To protect yourself from small glass fragments and crumbs, use transparent glasses and gloves. It is also recommended to carry out all work in special work clothes, since small particles of glass can get stuck in clothes.

Hole with wire

This method similar to the previous one, however, in this case, we replace the drill with a piece of ordinary copper wire. This piece is placed in the drill chuck. It is necessary to apply a special composition to the glass, which can be prepared in home environment. It is a paste that is obtained by mixing two parts of turpentine, one part of camphor and four parts of emery powder. The resulting paste is needed thin layer apply on the glass exactly in the place where you plan to drill a hole.

Needle file instead of drill

A flat file is a small file that is used for sanding small parts. However, if it is properly sharpened, then with its help it is quite possible to drill a hole in the glass. The file should be sharpened in the shape of a chisel, after which it is firmly fixed in the drill chuck and used as a conventional drill. The disadvantage of this method is that the needle file must be periodically removed from the cartridge and re-sharpened.

Glass drilling with tubes

To drill in this way, you will need working space. Perfectly clean glass sheet should be placed on a comfortable flat surface and fixed securely. First you need to mark a place for the hole, and then lay out a circle of plasticine about 1 centimeter high around it. Corundum powder diluted with water is poured into the formed "capacity". After that, you should carefully start drilling by clamping a straight copper tube into the drill chuck.

This method may also involve the use of a duralumin or aluminum tube. However, there are nuances here. A wooden plug should be hammered into one end of the tube, to a depth of approximately 25 millimeters. The other end of the tube is turned into sharp teeth with a small file with three edges. A screw is screwed into a wooden cork so that the cap protrudes above the surface of the pipe. The hat is sawn off, and pieces of cardboard with a ready-made hole of the size you need are glued to both sides of the glass.

Before drilling, it is recommended to put a sheet of glass on something rubber. This measure will avoid unnecessary glass vibration. Corundum powder is again poured into the drilling site. The sharp teeth on the tube are dipped into turpentine, and the end of the screw is clamped into the drill chuck. If the drilling is successful and the tube goes deep into the glass, after some time it is necessary to turn the sheet over and continue the drilling process, but from the other side.

How to get a large diameter hole in glass

No matter how good the ways glass drilling described above, they do not allow the creation of a sufficiently large diameter hole. This method is not drilling, but it is able to provide the result you need.

First, thoroughly clean and degrease the glass surface. After that, the place of the hole is marked, around which wet sand is laid out. There should be a hole in the center of the sand.

Further actions require maximum accuracy and compliance with safety rules. In a special container, it is necessary to heat the solder. Its temperature should be at least 250-280 degrees. There should be just enough solder to fill the prepared sand mold. Next, you just need to wait until the tin cools down, after which a piece of glass will fall off with it, leaving you with an even and neat

If there is a need to drill glass, people usually turn to a special company. In fact, you can do this work yourself, using the appropriate drills or sand. It will also be possible to drill glass using less traditional methods.

What do you need to know about glass?

Glass production is carried out by supercooling the melt. The speed of such a process is very high, which is why crystallization does not have time to end. The result is a very brittle material. This fact must be remembered when starting to drill a glass surface.

There are several types of glass. Depending on the materials used, the products are divided into oxide, sulfide and fluoride. If we talk about the scope, then glass can be window, glassware, optical, medical, protective, chemical, etc. At the same time, industrial varieties further divided into several groups:

potassium-sodium material has a low melting point and has a light structure;
the calcium-potassium variety is quite hard and difficult to melt;
lead product is quite fragile and expensive;
borosilicate material resistant to temperature fluctuations and various substances.

Many people wonder how to drill glass. For this purpose, it is necessary to have a suitable quality drill, as well as material capable of cool down the glass. Most often, specialists use one of the several types mentioned.

If you decide to do the work yourself, be sure to prepare the glass. The surface must be degreased with alcohol and wiped with a dry cloth. It is also important to make sure that the glass sheet does not slip on the work surface.

Drilling is carried out in several stages.

It is necessary to mark the drilling point. For this purpose, a marker or construction tape is used.
In order not to spoil the material, you should first practice on the fragments.
As a rule, the drilling procedure takes a lot of time. In any case, do not put pressure on the glass in order to speed up the procedure.
The material must be kept at a right angle. At the same time, while drilling one hole, it is worth making several pauses so that the product has time to cool.
When you're done drilling, turn the surface over and drill holes on the other side. This will help prevent cracks or chips from forming.
Fine-grained sandpaper will help to eliminate irregularities.

To drill glass at home, you need prepare the following:

a drill designed for drilling a ceramic or metal surface;
screwdriver;
turpentine;
alcohol;
plasticine.

The glass surface must be positioned so that it lies flat. Then you should insert the drill into a screwdriver or drill and make sure that it does not break the glass. After that, the surface is degreased and marked Right place plasticine. Next, you need to start drilling.

Using a homemade drill

To create holes in a glass surface, you can use homemade drill . Its main element is a diamond roller located in a conventional glass cutter. Alternatively, you can take a metal rod in which a hole is prepared for the roller. This variety is considered a good modification of the diamond-coated element.

If you need to make a hole in the glass with a maximum diameter of 50 mm, then you can take any drill, and then grab it with pliers and hold it for several minutes over the flame coming from the gas burner. When the shade of the tip becomes white, it is cooled in sealing wax. Thanks to such hardening, the product will be able to drill through almost any glass.

If for the first time you wondered how to drill glass at home, then when doing work, be sure to stick to simple guidelines.

Making holes with sand

If you think that a screwdriver or drill may not be effective, use ordinary sand. You will also need gasoline, lead, any metal vessel and a gas burner.

Glass must be degreased using gasoline.
Then wet sand is poured into the place of the proposed hole.
After that, a funnel is made with any sharp object. A mixture of lead or tin is poured here and after a few minutes the wet sand is removed.
After such a procedure, the frozen part will move away from the glass surface. To do this, the lead is preheated using a gas burner and a metal mug.

Unconventional ways to drill glass

If the above options are ineffective, then you can use other methods.

In everyday life, the need to drill glass is rare. Many people are afraid of such work because of the fragility of the material. In fact, there is nothing complicated here. Enough choose a special drill and start drilling carefully. You can also cut a hole in non-traditional ways.

Glass shelves, tables, boards for the kitchen are not only beautiful, but also practical. However, to make this shelf or table, you need to attach the glass to the rest of the parts using self-tapping screws. Not every person is able to correctly make holes in a transparent surface without damaging the glass itself.

Watch our video on how to drill glass at home and try decorating your home with original glass shelves.

To make holes in the glass, we need:
- a special drill, we will use a diamond-coated crown with a diameter of 8 millimeters;
- drill or screwdriver;
- glass;
- glass blank;
- scotch;
- masking tape;
- a container with water to cool the surface that we wake up to cool.

We insert the drill into the drill and clamp it well there so that the drill does not dangle during drilling, but is exactly in the center.

Before we start drilling our main element, we must first prepare our workpiece. To do this, we attach adhesive tape to it on one side, it is needed so that when we drill a hole in the glass, small fragments did not fly off or lay on the table, but were glued to the adhesive tape.

The place that we will drill is moistened with water. This is necessary in order to cool the glass surface and the drill itself.

It is impossible to immediately take and drill a hole in the glass, the drill will crawl over the surface. For this, we need a template so that by inserting a drill into it, we can easily drill a hole already in the material we need.

In order not to damage the table, place a small piece of cardboard or a regular board.

Everything is ready, remove the tape and wipe with a damp cloth.

Now you can start drilling through the blank of the main glass.

We glue the workpiece to the place where we will drill the hole and fix it with masking tape so that it does not go.

Pour the workpiece with water.

The workpiece can be removed when the drill fits snugly into the main glass and does not jump off to the side.

It is better to drill glass from two sides. For the second side, we also need a template to go deeper a few mm inward.

Then we remove everything superfluous from the glass with a cloth so that there is no dirt and smudges.

If you need to create an even and neat hole in the glass surface, it is not necessary to contact experienced and qualified specialists, whose services are quite expensive. This procedure can be done with your own hands in a home workshop, but, of course, for this you need to know how to drill glass, what tools to use, expendable materials and equipment.

To drill glass, use one of the methods discussed in this article.

Understanding the characteristics of the material

Before you wonder how to drill glass at home, you should at least in general terms get to know the characteristics and features of this material.

The glass production process is quite complex. Perform it on industrial enterprises equipped with special equipment. The main stage of this process is the preparation of the melt, which includes several components. Such a melt for glass is subjected to a sharp supercooling, while the crystallization process is not completed completely.

To prepare the melt, the mixture of components that make up the future glass is subjected to significant heating - up to 2500 °. Depending on what chemical basis the melt has, glasses are distinguished:

oxide category;
sulfide;
fluoride type.

Glasses, which may be opaque, are divided into Various types depending on the basic characteristics that the material possesses. So, glass is distinguished:

quartz, which is obtained by melting quartzite, also known as "rock crystal" ( given material may be of natural origin and occurs mainly in places where quartz deposits have been affected by lightning);
optical type used for the manufacture of the main elements of optical instruments (lenses, prisms, etc.);
highly resistant to aggressive chemical substances and elevated temperatures;
industrial use (the most extensive category of glass used in everyday life).

The question of how to drill a hole in glass most often arises when using the latter type of product. Industrial products, in turn, are also divided into several categories:

potassium-sodium type (such glasses, which are distinguished by a clean and light internal structure, have a relatively low melting point, so they are often used for the manufacture of glass products complex shape);
potassium-calcium type (glass of this type have a surface without a pronounced luster, are characterized by high hardness and are difficult to melt);
lead type (such glasses have a pronounced brilliance, which makes them very similar to crystal, high brittleness with a fairly high plasticity of the internal structure, a significant specific gravity and a higher price when compared with the cost of products of other types);
borosilicate (they are highly resistant to temperature extremes and mechanical stress and rather high cost).

There is also a classification of glasses by purpose. So, different kinds glasses are used for:

glazing of windows and other translucent structures;
container manufacturing;
reducing the level of radiation;
fiberglass production;
smartphone screen protection;
making dishes;
production of thermometers capable of measuring temperature in the range from –200° to +650°;
production of laboratory glassware (such glasses are highly thermally stable);
production of medical products (ampoules, tubes, containers for medicines);
fireplace screens and ovens (in such cases, heat-resistant glass is used);
the manufacture of electric lamps (in this case, the so-called electric bulb glasses are used);
production of incandescent lamps, x-ray tubes, ignitrons (this requires electrovacuum glass);
creation of elements of optical instruments - cameras, microscopes, telescopes, etc.;
production of thin-walled chemical containers and other products that require high resistance to chemical and thermal effects (quartzoid glasses, also known as vicor, are used for this).

What tools are used to drill glass

So that drilling glass does not end with its cracking and complete destruction, it is very important to know not only how, but also how to drill glass correctly. On the modern market there are many tools available, certain types which can be used to create holes in the glass.

The drill, the working part of which is made of hard alloy and has the shape of a pen or spear, allows you to make a hole in the glass with a diameter of 3–12 mm. The use of such a drill requires certain skills. However, even their presence and maximum accuracy when performing work will not help to drill glass with this tool without small chips.
To perform better drilling of holes allows a diamond drill on glass, the working part of which also has the shape of a spear. Such a tool, on the cutting part of which diamond coating is applied, provides softer drilling.
Drills for glass, made in the form of a tube, are used in cases where it is required to make a hole of large diameter in glass. More convenient to use tubular drill complete with drilling machine.
When using brass drills, on the cutting part of which diamond coating is applied, it is necessary to take care of their high-quality cooling, for which water or turpentine is supplied to the processing zone.
Tubular crowns on glass, made with diamond coating on the cutting part, also need high-quality cooling. If you do not know how to cut a large diameter hole in glass, this tube drill will help you solve the problem.

Product preparation

When wondering how to cut a hole in glass so that the hole formed in it is as accurate as possible, and the glass itself does not crack, it is important to know how to properly prepare it for processing. To drill glass with your own hands, you must perform the following preparatory steps:

The surface of the glass to be drilled is degreased with alcohol or turpentine. After that, it must be wiped with a dry cloth.
The glass sheet or mirror must be laid on a surface that will prevent the product from slipping during processing.
The surface on which the glass sheet or mirror will be laid must be larger than the workpiece itself. The edges of the sheet should not be allowed to protrude beyond its limits.
It is advisable to stick masking tape or a piece of plaster on the place that needs to be drilled to prevent the tool from slipping.
The center of the future hole is indicated using a conventional marker.
If you are familiar with drilling glass at home only from the video, then in order to gain practical skills, it is better to first practice on unnecessary glass fragments. Such training will allow you to subsequently drill glass with high quality.
Drilling holes in the glass should be done as carefully as possible, without too much haste. At the same time, minimal pressure should be exerted on the tool used.
The drill for glass and ceramics, which will be used to perform the processing, should be placed strictly perpendicular to the surface of the product.
Do not drill holes in glass in one pass, stop the process periodically to allow the tool to cool completely.
When the glass sheet or mirror is almost completely drilled, stop the process, turn the workpiece over and continue from the back of the workpiece. This approach will allow you to drill a hole in a mirror or glass sheet with the highest quality, minimizing the risk of chips and cracks.
To make the edges of the hole you have drilled even neater, you can further process them with sandpaper small fraction.

Drilling glass with a conventional drill

Many home craftsmen are interested in the question of how to drill glass or a mirror, using not a tubular or other special drill for this, but an ordinary tool. In order to perform this procedure, you will need the following tools and supplies:

a drill with which metal, ceramic and tile material is usually drilled;
low-speed drill, instead of which you can use a screwdriver;
a piece of ordinary plasticine;
turpentine;
alcohol solution.

Drilling itself is performed in the following sequence:

The glass sheet or mirror must be laid on a completely flat surface, while the edges of the workpiece must not protrude beyond its limits.
The section of glass to be drilled must be degreased using cotton wool soaked in an alcohol solution.
After fixing in the drill chuck for tiles and glass, the minimum number of revolutions is set on the drill. Before starting work, it is necessary to check the degree of runout of the drill: if it is too large, then the tool should be replaced with another one.
On the surface of the glass to be drilled (in the place of direct processing), it is necessary to fix a piece of plasticine, in the middle of which a small depression is made in the form of a funnel. Turpentine is poured into such a recess, through which holes are drilled in the glass.
In order not to throw away the cracked object after drilling, such a process should be carried out as carefully as possible, without much effort. The minimum rotation speed of the drill chuck must be 250 rpm, and the maximum cannot exceed 1000 rpm.

How to make a hole in glass with sand

Few people know how to make a hole in glass using ordinary sand. You will need:

the sand itself;
petrol;
a small amount of tin, which can be replaced by lead;
gas-burner;
a vessel made of metal, for which it is permissible to use an ordinary mug.

The surface of the glass to be drilled is degreased, as in all previous cases. A hill of wet sand is poured onto the area where the center of the future hole should be located, in which, using a sharp object, a recess is made with a diameter corresponding to cross section created hole.

Molten tin (or lead) is poured into the recess formed in the hill of wet sand, after which it is necessary to wait a few minutes. Then the sand is removed from the surface of the product, and a piece of metal-glass alloy is easily removed from the processed material, the dimensions of which fully correspond to the geometric parameters of the hole being formed. A gas burner and a metal cup are used to bring tin or lead into a molten state.

The cut made according to the above method is different high quality and does not require further modification.

Using a homemade drill

You can drill glass by making your own tool for this, the design of which includes a diamond roller from a glass cutter and a metal rod. The diamond roller, which will act as the cutting part, is tightly fixed in the slot made on the end part of the metal rod. By fixing such a tool in a drill chuck, you can drill any glass product, and the result will be of sufficient quality.

By hardening an ordinary drill, you can endow it with the ability to drill through glass. To do this, the working part of the drill must be heated to white with a gas burner, and then cooled by lowering it into sealing wax.

How to drill glass correctly in order to get a high-quality result as a result? To solve this problem, it is enough to adhere to the following recommendations:

To minimize the risk of cracks and splits at the drilling site, the glass can be treated with honey and turpentine.
The pressure exerted on the drill from above should be minimal.
The drilling process itself must be performed for 5-10 seconds, after which it is necessary to cool the tool in a vessel with water.
The drill must not be moved from side to side.
The distance of the center of the hole from the edge of the workpiece must be at least 1.5 cm.
