How to make holes in glass. How to drill glass at home with your own hands. Necessary tools and equipment

If you need to create an even and neat hole in a glass surface, such as a glass block, 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, supplies and equipment to use.

WE UNDERSTAND THE FEATURES 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.

For the manufacture of bottles, oxide glass is used (it is also silicate)

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" (this material may be of natural origin and is found 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 to manufacture glass products of complex shape);
potassium-calcium type (glasses 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 more high 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).

In most cases, window or display glass drilling is required

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).

Drilling thick glass is best done on a machine

WHAT TOOLS ARE USED FOR DRILLING 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. It is more convenient to use a tubular drill complete with a 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.

The main types of glass drills

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.
In the place to be drilled, it is advisable to stick masking tape or a piece of plaster to prevent the instrument 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 fine fraction.

DRILLING GLASS USING 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.

A side on plasticine glass is needed to hold the coolant in the drilling zone

Drilling itself is performed in the following sequence:

The glass sheet or mirror must be laid on absolutely flat surface, while the edges of the workpiece should 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.

There are situations when you need to make a hole in the glass. You can turn to specialists for help - they know how to carefully drill glass without breaking it, but many home craftsmen prefer to do it themselves.

Drilling methods differ from each other by the type of tool used, consumables, drilling technology and other points.

Glass characteristics and production features

Before drilling a hole in glass, you should understand the features of this material. Its production process is quite complicated, as it involves use of special tools:

The main stage of production involves the creation of a melt, which includes certain components. This requires exposure to a temperature of about 2,500 degrees Celsius.
To create a strong structure, the molten composition is rapidly cooled. Due to this, the hardened alloy crystallizes.

It is the chemical composition of the alloy used that determines the main operational qualities, as well as the likelihood that the structure will not crack during machining.

Depending on the chemical composition allocate the following glasses:

Sulfide.
Oxide.
Fluoride.

Different glass products should have different performance characteristics.

There are glasses:

Optical. There are various optical devices, the main part of which can be called a combination of prisms and lenses. For their manufacture, special glass is used.
Quartz. When melting quartzite, glass can be obtained, which is used in the manufacture of various dishes and decorative elements.
With high protection to chemical attack. Some types of glass can withstand exposure to petroleum products and other chemicals. They are used in the manufacture of containers and protective structures.
Industrial purpose. This group has become widespread in industry and everyday life.
Hardened material with higher strength. Glass can be tempered in a variety of ways.

According to the area of application, they distinguish the following materials:

For the manufacture of containers.
For glazing window frames.
Reducing the level of radiation.
in the production of fiberglass.
Protect the screen of mobile and other devices.
For making dishes.
For the manufacture of medical devices.
Protecting the surface of the oven and fireplace screens.
For the manufacture of various light sources.
For the manufacture of various optical devices.

It should be borne in mind that some glasses cannot be machined. This is due to the fact that their structure has a high rate of fragility. Cut out round hole can be in a jar, on a glass plate and many other products.

What tools are needed

To drill a hole in glass, you can use various tools. Correct selection tool allows you to exclude the possibility of damage to the material during processing. The most common varieties are:

Diameter cutting tool must correspond to the diameter of the hole to be obtained in the product.

Preparing a glass blank

It is possible to make a hole in the material correctly if the workpiece is carefully prepared. The instruction looks like this:

Surface treatment with alcohol or turpentine. Then clean the surface with a clean cloth.
The workpiece must be positioned on the base so that it does not change its position during processing.
The base on which the workpiece will be laid must be larger. The edges of the glass must not be allowed to extend beyond the base, as carelessness can damage it.
Masking tape is glued to the surface where the hole is drilled. This will prevent slippage of the tool at the beginning of processing.
The center of the hole can be marked with a marker.
If the work is carried out for the first time, you can make a test hole on unnecessary glass.
When performing drilling work, you should be as careful as possible. Haste can cause serious defects.
When working with glass or ceramics, you need to ensure that the drill is located strictly perpendicular to the surface - so the hole will be of high quality.
It is not recommended to process in one pass. This is due to the fact that glass is considered difficult to process; during prolonged drilling, the cutting edge may heat up. When the tool is heated, part of the heat is transferred to the material, deteriorating its performance.
When through hole almost received, you should stop the process, then turn the product over and continue drilling from the reverse side. So you can get a quality hole.
You can finish the edges with sandpaper. It is recommended to choose paper that has a fine fraction.

The use of a conventional drill

If glass processing does not involve mass production, then there is no need to purchase special tools. Its cost is quite high, with long-term operation, the surface of the cutting edge wears out. Here's how to drill a hole in glass with a conventional drill press. You will need:

Drill for working with metal or ceramics. In their manufacture, a hard alloy is used that can withstand long-term operation.
Drill with low speed and drilling machine with the ability to adjust the number of revolutions.
Ordinary plasticine.
Turpentine.
Alcohol solution.

Drilling instruction:

The glass is placed on a flat surface. The edges should not go beyond it.
The processed area of glass is degreased.
After fixing the tool in the chuck, set the minimum speed. Too high rotation speed of the drill can lead to deformation of the workpiece. In addition, the degree of runout of the tool must be low, as a variable load can lead to cracking.
Plasticine is placed on the surface to be treated, which will eliminate the possibility of the tool slipping. A small hole is created in the central part.
To reduce the likelihood of cracks, work should be done carefully. Too much force causes various defects. The minimum rotation speed must be 250 rpm. With a high resistance of the material to mechanical impact the indicator is set to 1000 rpm.

During machining, chips of fine fraction are formed - when working, use protective glasses.

Benefits of using sand

When using a cutting tool, the surface is likely to be damaged. The use of sand will help to avoid this. You will need:

Fine sand.
Petrol.
Gas-burner.
Small amount of tin.
A vessel made of metal.

Work order:

The surface is degreased. To do this, you can use an alcohol solution.
In the area where you need to get the required hole, a hill of sand is poured. It is slightly dampened.
With the help of a sharp object, a small indentation is created.
Molten tin is poured into the created recess, after which you need to wait a bit.
A hill of sand is removed from the surface. After that, the tin is melted with a gas burner.

It should be borne in mind that it is rather difficult to obtain a high-quality hole in this way, therefore, machining the hole with a drill is additionally necessary.

Even minor errors can lead to serious defects in the processed material. Here are tips on how to make a hole in glass and don't damage it:

The same methods are also suitable for those who are going to drill a mirror at home. To receive big holes a special tool called a glass cutter should be used. Design features allow you to get high-quality holes in the shortest possible time.

Periodically, situations arise that require the creation of holes of various diameters in glasses. For example, this is required when mounting mirrors or when installing various devices on glass. This is a very rare type of work, and therefore calling a specialist can be very expensive.

Can be done on your own necessary work and do without the services of a master. However, you need to understand that glass is a rather fragile and expensive material, so you should carefully prepare before you start drilling.

Composition and stages of production

Ordinary glass contains quartz sand, lime and soda. Various additives greatly affect the final properties of the material, but quartz sand remains the main component, and its amount reaches 75% in the mixture. The lime component adds shine, strength, and protects against many chemicals. Soda can significantly lower the melting point of the mixture. To the most common additional components include:

Lead gives extra shine and ringing.
Manganese, nickel and chromium are used to obtain various shades.
Boric acid gives strength, shine and lowers the coefficient of thermal expansion.

Industrial glass production includes the following steps:

There are currently many types this material, depending on the components used in production. The most common are:

Nozzles for drilling and rules of work

Most often, the need for drilling occurs when using industrial glasses, quartz, crystal. These types are often fragile, so unskilled attempts to make holes most often end in damage to the workpiece, so the process must be approached very responsibly.

Drills for metal and concrete are not similar in shape to special glass drills. They must be used very carefully, and if possible, then not used at all. But if only these types of drills are available, then it is best to use carbide concrete or spear-shaped drills for tiles. Drills for metal must be hardened.

There are also special nozzles designed specifically for glass:

Carbide drills of feather-shaped or spear-shaped form of various diameters. It is highly desirable to use those that have diamond coating on the cutting part.
A drill presented in the form of a tube. This type of glass drill can be used when you need to make a hole of a large diameter. When working with this nozzle, it is advisable to use a drilling machine.

When carrying out drilling work, you must adhere to the following rules:

Surface cooling can be done in several ways:

Cover the drilling site with plasticine and pour water.
Lay a moistened rag or cotton ball around the hole to be treated so that the water gradually flows into the recess.
You can wet the drill itself, and a break in work will allow the drilling tool to cool.

Ways to make a hole in glass without a drill

In the absence of a drill and the possibility of acquiring it, you can make holes by other methods or make a homemade drill, but such methods do not have high precision and quality, as a result of which they can lead to damage to the glass surface. But still, some methods can theoretically be applied, so they should be listed.

With sand and solder

Quite an interesting way that does not require drilling skills and tools. To use it you will need:

Sand.
Low-melting solder, for example, tin-lead.
A container in which this solder will be melted.

The surface in which you want to make a hole should be degreased and dried, after which a slide is poured onto the area in which the hole should be located. wet sand. Next, you need to make a recess in it of such a diameter that the hole being created requires.

Solder melted with a torch or soldering iron is poured into the formed hole, after which you need to wait for it to completely harden. With the subsequent removal of sand and hardened solder, a hole of the desired diameter remains on the glass.

This method differs high quality and hole accuracy.

Making a homemade drill

In the absence of special nozzles for working with glass, you can make them yourself.

To do this, you need a metal rod and a simple glass cutter with a diamond roller. To turn it into a drill, you need to cut a hole in the rod, into which the roller is inserted and fixed so as to remain motionless relative to the rod.

The resulting workpiece is fixed in the drill chuck, and then drilling is carried out according to the principle of a conventional drill.

You can also prepare conventional drill, for example, for metal to work with glass. To do this, clamp it in a vice or pliers and hold it in a flame gas burner until the metal is white hot. After that, the drill is dipped into warm water or oil. The tool thus hardened is suitable for glass drilling.

With a metal tube

A piece of metal tube is also suitable for making a hole in the absence of a drill. To do this, cuts are made on the part of the pipe that will be cut to create a cutting part in the form of teeth. When applying such works, auxiliary abrasive powders or pastes should be used, but this way quite laborious and often leads to damage to the workpiece.

Using a glass cutter

An ordinary glass cutter can also replace a drill, the main thing is not to make sharp jerky movements, not to put pressure on the glass, and to tap the formed cut surface with the handle of the tool.

To cut holes of large diameters with a glass cutter, you can use a compass, fixing one part of it in the center of the intended hole, and the second part (on which the glass cutter is fixed) to cut the surface.

Often there is a need to drill glass at home. Videos of these works can be found on the Internet, they cover such topics well. plain language with illustrative examples.

Work, if possible, is best done with a screwdriver, and not with a drill. This will give more soft way drilling and reduce the chance of damage to the glass surface. In addition, it is recommended to use protective glasses and clothing, and drilling should be carried out in non-residential premises.

It is important to observe the minimum indents from the edge of the workpiece: for fragile materials - at least 25 mm, for common species glass - at least 15 mm.

It should be remembered that glass is a rather fragile and expensive material, so you need to work with it very carefully. In the absence of experience in such work, it is important to practice on unnecessary pieces of glass in order to gain experience and understanding of the process.

Any man should know how to drill a hole in glass if you do it with a special drill. You can also buy an ordinary metal drill, which is also convenient to make holes in a mirror or glass. If you take on this species work with insufficient experience, it is possible to spoil the glass so that it cracks. Therefore, you should take up the work without overestimating your capabilities. If there is uncertainty about own forces, it is better to seek help from an experienced master.

Glass drilling rules

If you have to drill a hole in any glass, it is better to practice first so that it does not burst on any unnecessary piece of glass. When doing the work, a considerable amount of diligence, accuracy, patience and care will be required. In this case, be sure to follow the safety rules, otherwise trouble may arise. Be sure to wear gloves and goggles before drilling a hole.

When drilling glass close to its edge, be sure to take into account the thickness of the material. If the glass is thick, then the holes must be made, departing from the edge by 25 mm, and if it is thin, then retreat at least 15 mm from the edge.

When working with a drill, you should remember that you need to do the work carefully, otherwise you can damage a fragile object. If you have to work with a mirror, then it has the same properties as glass.

Before starting work, the glass is cleaned of dust and dirt. After that, you should carefully wipe the place where you need to drill a hole with a material moistened with gasoline or turpentine. To mark the places for drilling, you need to take a marker. In the process of performing the work, a manual or electric drill can be used.

Tools for drilling holes in glass

The process of drilling a hole in glass is associated with the use of such types of tools as:

Carbide drill with diamond coating.
A special liquid that allows you to wet the drill or the glass itself.
Marker.
Electric or hand drill.
glass cutter
Sealing wax.

If you need to drill a hole small size, then it is best to use a diamond drill. For this purpose, a conventional drill with a small diameter is also suitable, if right tool is absent. The end of the drill is recommended to be hardened, for which you just need to heat the drill. After a sharp indentation into the prepared sealing wax of the end of the drill, which has turned white, you should wait for the tool to cool. If the sealing wax no longer melts, then work begins on drilling holes in the canvas.

To drill glass or mirrors, you can use a special diamond-coated tubular drill and a drill with a speed control.

It is very convenient to make holes with a screwdriver, and not just with a drill. Markup is not done with conventional way, that is, a cross placed in the center of the hole. Having decided on the diameter of the future hole, put a mark in the form of a square.

If a beginner uses a drill, then it begins to slip strongly from the required mark. To avoid this, you can use a small piece of wood or plastic. It is fixed in the place of the glass where there is a mark, for which adhesive tape is used, and the drill is held during the work.

It is important to prevent possible overheating of the drill, for which special stops are periodically made. Stopping, the tool together with the product is cooled by wetting them with water. Continue drilling at low speed. It is not necessary to make sharp or vigorous movements when making holes in the glass, since its structure is very fragile.

Carrying out preparatory work before drilling

After laying the glass on a surface that is not only perfectly flat, but also strong, otherwise the material will crack, markings begin to be made. It should be ensured that the glass product is positioned evenly, being motionless. Before that, you need to take a piece soft tissue and lay under the canvas. Before drilling, a hole is marked, the contours of which should be applied with a glass cutter. The frequency of rotation of the drill is adjusted to a level of no more than 350 rpm.

To install a drill to perform work in the required place, a recess must be made. For this purpose, a roller type of glass cutter is installed, which should be rotated along the axis to form a recess. After that, drill with a drill. You can avoid overheating of the drill by working without increasing the number of revolutions, be sure to wet the drill and the glass object with water.

To prepare glass for drilling holes in it with a larger diameter than the diameter of the drill, it is degreased and the place where it is necessary to drill is marked with a marker. First make a hole small size, and then a nail of the appropriate size or a bolt is inserted into it, which will hold tightly.

Next, a rope is tied to the nail, and on the other hand, its end is tied to the glass cutter. They make a special circle, its radius is equal to the length of the rope. When the circle around the nail is made with a glass cutter, it is removed by gently tapping the canvas so that the circle made comes out of a hole of a larger diameter, the edges of which are processed with sandpaper.

How is glass cutter used?

Drilling glass with a glass cutter requires the use of a diamond roller. After that, a special metal rod is prepared, in which it is required to make a slot by cutting out. You can fix the roller using a rivet, which will allow it to be rigidly fixed so that there are no twists. When the drill is ready, it is attached to the drill, after which they proceed to making a hole in the canvas.

When the object is laid on a perfectly flat surface, it is degreased, then the contour along the mark is drawn up with a plasticine bath. Its sides should be neat. It should be on the upper side of the object, after which liquid should be poured into it. It can be not only water, but also turpentine. The sides allow you to fill the bath with a small amount of liquid only once. The main thing is to drill without special efforts drill set at low speed.

When choosing a carbide drill, it is imperative to consider one important point, which is associated with heating the drill with glass during the drilling process. The end of the drill should be cooled in a timely manner with turpentine or another liquid that promotes cooling, which will make the hole perfectly neat. Drip turpentine should be in the recess, which is received.

To cool the drill, use a liquid containing aluminum alum, which is dissolved in acetic acid. Instead, a special mixture can be used, obtained using camphor with turpentine in equal parts. Therefore, to create protective bumpers, the use of plasticine is required.

If, while doing work, in a hurry, accelerating and pressing on the drill, you can spoil the glass object. It is drilled to the very half of the thickness size, then it turns over, then again they continue to drill a hole on the other side towards the first one. So you can avoid chips from the outer sides of the canvas. This method should be used when doing work at home.

When doing work at a very slow pace with the application of weak efforts, the pressure force must be controlled. You need to carefully monitor the speed at which the drill of an electric drill rotates. If you want to perform this type of work using bottles or other glass objects with seams, it is better to step back from the seams. This will increase the chances of maintaining the integrity of the bottle or other item.

When you need to drill a hole in the glass, then most of of people, most likely, will immediately turn to the services of specialists who will do this work for you and require a certain fee. In truth, this process is not as difficult as it seems at first glance. Below we will talk about how to drill a hole in the glass and what tools to use for this.

Preparatory activities

Before drilling glass at home, the material should be prepared:

So, for this purpose, you will need the following devices:

drills for metal or ceramics;
screwdriver or drill with low speed;
plasticine;
pure alcohol;
turpentine.

Before making a hole in the glass, it must be placed on a flat surface.. There are some nuances here: the ends of the sheet should not hang down and / or stagger.

On the power tool, select the minimum rotation speed. The drill must be clamped into the chuck. Then you can start drilling the hole.

Degreasing the surface must be done with pure alcohol, and then a plasticine recess should be fashioned in the area of \u200b\u200bthe future hole. There you need to add a little turpentine. To prevent cracks in the material, do not press too hard on the tools.

Sand for drilling glass

In a period when there were no screwdrivers and drills, glass surfaces were drilled by hand using sand. To make a hole in this way, you will need the following:

the sand itself;
tin or lead;
burner;
metal alloy container.

First, you should use gasoline to degrease the surface, and then make a hill of wet sand at the drilling site. Next, using some sharp object, you should make a funnel, the dimensions of which will correspond to the dimensions of the future hole.

It is necessary to pour a pre-prepared composition of tin or lead into the prepared form. After five to seven minutes, remove the sand and remove the frozen glass. The piece should easily peel off the surface. The hole should turn out to be very even, it does not even need any additional processing..

To heat lead or tin, use metal container and gas burner. If you do not have a gas burner, then you can use an ordinary gas stove.

Drilling with a homemade drill

Drilling glass sheets at home involves the use of a special drill, in which there is a diamond roller. To make such a device, you need to create a cut in the rod and place this same roller in it.

Having made a drill, install it in a drill or screwdriver, after which you can get to work.

Another option is to take an ordinary drill, squeeze it with pliers and hold it over the flame for 5-10 minutes. After the drill begins to turn white, it should be promptly cooled in sealing wax. This is how the tool is hardened.

Using a glass cutter

This tool is great for creating large holes. unusual shape. The sequence of work in this case will be as follows:

Using a marker, select the contours that will be processed.
When using a glass cutter, do not make too sharp manipulations. You need to press on the device smoothly and as evenly as possible.
To make the cut piece fall off, gently tap the tool handle on the surface.
To get rid of excess material, use special tongs.
Check the condition of the device beforehand. The cutting roller must be located strictly in the middle.

Unusual glass drilling options

To make a hole in tempered glass, you need to prepare a coolant in advance. It can be done like this: dissolve aluminum alum in vinegar. In the event that you do not have them on hand, mix camphor and turpentine in equal proportions. Treat the coating with the resulting mixture, and then you can get to work.

If you don’t have a drill, then you can use copper wire by holding it in a drill. For this, a special solution should also be used, consisting of one part of camphor, two parts of turpentine and coarse-grained emery powder. The composition should be placed on the area where drilling will be performed.

To avoid cracks and chips, it is recommended to apply a small amount of honey or turpentine to the area where the hole will be made.
When drilling, take small pauses of 5-10 seconds. At the same time, dip the drill in cool water to enhance the effect, otherwise it may melt.
Do not rock the tool in different directions.
Instead of alcohol, you can use acetone.
When working, do not forget about safety precautions: use safety goggles and gloves.
The hole must be located at least one and a half millimeters from the end of the glass sheet.
It is desirable to work with glass on wood surfaces.
