Cut a hole in the glass in place. How to make an even hole in glass with a hammer. How to make a hole in glass using wire

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 a 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 a 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.

If you need to drill glass, then the easiest way is to entrust this matter to a specialist. But firstly, such services are not cheap, and secondly, there are people who like to make their own. Let's try to figure out how to make a hole in the glass without damaging it. Consider what tools you can use in this case, how quickly and accurately you can do the work ahead.

Preparatory work

Before drilling glass at home, you must carefully prepare it:

Using ethyl alcohol or turpentine, wipe the surface. This is necessary in order to degrease it.
When working, it is unacceptable for the sheet to slide off, so this moment must also be foreseen.
Choose a base so that the sheet is located on it completely.
Before starting work, mark the place where you will drill. Use construction tape or a marker for this.
If drilling glass with your own hands - new job for you, then practice on small pieces first to avoid damage to the main sheet.
The drilling process is quite slow. No need to press on the glass to get the job done faster.
Position the drill at a right angle to the plane. Don't try to make a hole right away. Let the glass cool down periodically.
After the perforation is almost done, turn the sheet over and finish on the other side. This will allow you to get the perforation of the correct shape, and at the same time avoid chips and cracks.
If small roughness or irregularities have formed on the surface, processing the glass with fine sandpaper will help get rid of them.

How to drill glass at home with a conventional drill?

To successfully complete this task, you will need:

A set of drills used for metal or ceramics.
Screwdriver or low speed drill.
Plasticine.
Turpentine.
Alcohol.

Operating procedure:

Place the glass sheet on a flat surface.

Important! Pay attention to the fact that the edges do not hang.

Set the screwdriver or drill to the lowest speed.

Important! Drilling speed ranges between 250 and 1000 rpm.

Clamp the desired drill in the chuck.
Using an alcohol solution, degrease the surface, and then make a plasticine recess in place of the future hole.
Pour some turpentine into it and start working with a drill.
Do not apply too much pressure to the tool as cracks may form.

Sand use

This is enough old way. It was used when there were no screwdrivers and drills. To drill glass with your own hands using this unusual method, you will need:

Petrol.
Sand.
Tin (it can be replaced with lead).
Gas-burner.
Metal mug.
Sealing wax.

The algorithm of actions is as follows:

Degrease the surface with gasoline.
In the place where the hole is to be made, pour some moistened sand.
Using a sharp object, make a hole in the sand, the diameter of which is equal to the size of the future perforation in the glass sheet.
Melt tin or lead in a metal mug using a gas burner.

Important! If there is no burner, then you can heat the metal in a mug and on a gas stove.

Pour the molten lead into the prepared hole.
When the metal hardens, remove the sand and take out the hardened glass. The resulting hole will be perfectly shaped and will not need to be machined.

How to drill a hole in glass at home with a homemade drill?

To make a homemade drill, you will need a diamond roller from a glass cutter and a metal rod:

Saw a groove in the rod to insert the roller into it. You need to fix it so that it is motionless in relation to the metal rod.
Fix the drill made in this way in a screwdriver or drill and start drilling. This is equivalent to the fact that you are perforating with a diamond-coated drill.

Important! If for some reason you cannot buy a factory-made drill, then you can make it yourself.

There is another way to independently prepare the drill for work in order to drill glass at home:

Clamp a regular drill in pliers and hold for several minutes over the flame of a gas burner.
After the tool is white hot, cool it with sealing wax.
After the drill has cooled, remove the remaining sealing wax.
With this simple manipulation, you get a durable tool that can make holes in a tempered glass sheet.

To avoid cracking of the material, apply a little turpentine or honey to the surface at the drilling site.
Do not press the screwdriver or drill while working, do not shake the tool from side to side.
Take breaks of 5-10 seconds. During breaks, lower the drill into a vessel with cold water for cooling.
If you choose between a drill and a screwdriver, give preference to the latter, since the drilling mode in this case will turn out to be more gentle.
For surface treatment, you can use both a solution of ethyl alcohol and acetone.
Do not forget about safety precautions - you need to work in goggles and gloves.
The minimum distance from the point of drilling to the edge of the sheet: 15 mm for fragile grades, 25 mm for ordinary glass.
It is desirable to place a glass sheet on a wooden surface.

Glass cutter application

This tool can be used to create holes large diameter or complex shape. The algorithm of actions is the following:

Apply with a marker or felt-tip pen contours for further processing.
Press the tool smoothly and evenly, do not make sudden movements.
To fall off the cut off part, gently tap on the surface with the handle of the tool.
To remove glass residue, use special tongs.

Important! Before you start working with glass, check the condition of the tool. It is necessary that the roller is in the center of the glass cutter, rotates freely and evenly.

Surprisingly, it is a fact that with a hammer you can make an even hole in the glass of any geometric figure, be it round hole or square.

In the article we will look at how to make a hole in the glass with a hammer.

	1. Take for example a square piece 18 by 18 centimeters, 4 mm thick. Look at the glass to make sure it doesn't initially have defects such as cracks and scratches, as this will decrease your chance of success in punching a hole in the glass.
	2. We use a glass cutter, the tip of which is lubricated with oil (machine or sunflower). For example, in the center of the glass, we apply a geometric figure with a glass cutter, in our case it will be a square.
	3. Place a soft surface, such as a towel, on top of the glass, then lift the glass so that only one edge touches the table surface. Using a hammer, begin to apply light blows to the glass, to the cut points with the glass cutter. See if there are cracks in the places of the cut, if not, then strike a little harder. After cracks have appeared throughout the cut, then with a small hammer blow to the center of the hole, remove a piece of glass from the main sheet.
	4. If you're lucky, you'll get an even hole in the center

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, supplies and equipment to use.

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

Understanding the characteristics of the material

Before wondering how to drill glass at home, you should at least in general terms get acquainted with 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 can also be opaque, are divided into different types depending on the main characteristics that the material has. 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 chemicals 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 sufficiently high ductility internal structure, a significant specific gravity and a higher price when compared with the cost of other types of products);
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. There are many tools on the market today, some types of which can be used to create holes in 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.

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 drilled even neater, you can further process them with fine sandpaper.

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 into 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 the cross section of the hole being created.

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 method described above is of high quality and does not require additional refinement.

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.

Naturally, before drilling glass, you must degrease it and lay it on a flat surface, which is best used as a wooden base.

Glass cutter application

You can drill a glass sheet not only with a tubular drill or processing tool ceramic tiles. An ordinary glass cutter is also used to create holes in this material. How to drill (cut through) glass using such a tool? Simple rules should be observed: the glass cutter must not make sudden movements, while gentle pressure is exerted on it, and during the processing, the formed cut is tapped with the tool handle.

Non-standard glass drilling methods

As non-standard methods for making a hole in the glass, the following can be mentioned:

use as a cutting tool copper wire, a solution consisting of one part of camphor and two parts of turpentine, to which an abrasive powder is added;
the use of a metal tube as a cutting tool, which is also used together with a special solution and abrasive powder;
drilling with a piece of a tube made of aluminum, copper or duralumin, on which cutting teeth are previously made (drilling according to this method is also carried out using a special solution and abrasive powder).

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.

Various glass products must 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 chemical resistance. 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. You can cut a round hole in a jar, on a glass plate and many other products.

What tools are needed

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

The diameter of the 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 the through hole is almost obtained, 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 stress, an indicator of 1000 rpm is set.

During machining, chips of fine fraction are formed - safety glasses should be used during work.

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. Thereafter gas burner tin melts.

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. For getting 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.
