Make a big hole in the glass. How to make holes in glass yourself

How to make a hole in glass

Making holes in glass.

There is an old, but for some reason now forgotten method for making holes in glass. The place on the glass where there should be a hole is thoroughly washed from dirt and grease with gasoline, acetone or alcohol. Then wet fine sand is poured onto the washed place and a funnel is made in the sand to the glass with a sharpened stick of the desired diameter. Molten solder is poured into the mold prepared in this way in sand (lead or tin can be used). After 1-2 minutes, the sand can be dropped and the solder cone removed. An even through hole is formed in the glass.

Drilling holes in glass.

A hole in the glass can be drilled with a carbide drill. The secret of the success of this operation lies in the liquid with which the glass is wetted. It is prepared from aluminum alum dissolved in acetic acid, or from a one-to-one mixture of camphor or turpentine. A plasticine roller is made around the drilling site. Liquid is poured inside the resulting bath. Glass during processing should lie on a soft cloth.

Another way to make a hole in glass.

To work, you will need a hard alloy drill, plasticine for making a small bath, a mixture of equal parts of camphor and turpentine, as well as a piece of dense rubber.

How to drill a hole in glass in 10-15 minutes. To do this, you need to sharpen a flat file like a chisel and fix it in the chuck of a hand drill. Do not forget to only allow the needle file to cool during drilling and periodically undermine it.

Drilling a large hole in glass.

The drill is made from a piece of aluminum, duralumin or copper tube 40-60 mm long. From one end, a wooden cork is hammered into it to a depth of 20-25 mm, and at the other end, teeth are cut with a trihedral file. A short screw 4-5 mm thick is screwed into the cork so that its smooth part protrudes by 10-15 mm. The head is cut off. A cardboard washer with a hole equal to the diameter to be drilled is glued to the glass on both sides. Glass is placed on a piece of rubber. A pinch of abrasive powder is poured into the drilling site. Then insert the end of the screw protruding from the cork into hand drill, lubricate the teeth with turpentine and begin to drill. When the tube goes deep into the glass by at least 1/3 of its thickness, the glass is turned over and drilling is completed on the other side.

Cutting round glass.

We offer a method of cutting round glasses. A roller from a glass cutter is attached to one sponge of the caliper. Another sponge rests on the glass through a rubber washer. The roller is rolled several times in a circle, after which 3-4 tangents are made with a conventional glass cutter, which facilitates chipping the glass along the boundaries of the cuts. Sharp edges are cleaned with a file or emery under running water.

Circle markings on glass.

A master tempted by experience will never start marking a circle on a slippery surface before he sticks a piece of adhesive tape or electrical tape in the center of the circle (under the leg of the compass).

Curvilinear cutting of glass.

Glass can be cut along any curved line with a soldering iron.

A risk is made on the edge of the glass at the beginning of the line with a needle file. A few millimeters away from it along the line of the future cut, the glass is heated with a soldering iron tip until a crack appears from the risks to the place of heating. So, gradually moving the soldering iron, we pass along the entire line. To speed up the process, you can periodically cool the glass with a damp cloth.

Glass drilling

1. Small holes in the glass are drilled with a conventional drill, which is pre-hardened. The tip of the drill is heated to white, and then it is quickly pressed into the sealing wax and held until the sealing wax stops melting. When drilling, the tip of the drill is abundantly moistened with turpentine. Small glass objects can be drilled in water.

2. A hole in the glass can be drilled with copper wire. To do this, you need to prepare a paste consisting of large emery, camphor and turpentine. One part of camphor in powder is dissolved in 2 parts of turpentine and mixed with 4 parts of coarse emery. The resulting paste is applied to the place where it is necessary to drill a hole. A piece of copper wire is clamped into a drill chuck. It is convenient to drill glass through plywood (jig) with guide holes. The glass must rest on a hard and level surface.

3. To drill a hole with a diameter of more than 4 mm in thick glass, a copper tube is used. On the glass around the alleged hole, a plasticine or putty fence is made in the form of a ring with inside diameter 40-50 mm and 8-10 mm high. Corundum powder is poured inside the ring (it is easy to prepare by grinding a piece of an unusable emery wheel). The powder is poured with a small amount of water to make a liquid slurry. Drill holes with a copper tube clamped in a chuck drilling machine. The diameter of the tube should be slightly smaller than the diameter of the selected hole. It is very important that the end of the tube is strictly perpendicular to its axis - this can be easily achieved by cutting the tube on lathe.

4. A hole in the glass can be made with molten solder. On the surface of the glass, previously carefully degreased with acetone, gasoline or alcohol, pour small hill slightly damp river sand. With a sharpened stick, a conical recess is made in it and a platform equal to the future hole is cleaned of sand. Molten solder with a temperature of 250-300 °C is stuck into the resulting sand mold. After the solder has cooled, the sand is removed, and the solder cone is removed along with the glass circle stuck to it.

Non-traditional glass drilling methods.

1. A thin steel drill, heated to white, is hardened in mercury or a piece of sealing wax and honed. Then a saturated solution of camphor is prepared in turpentine, a drill is moistened with it, mounted on a brace, and glass is quickly drilled, which is then wetted at the point of convergence with the named solution. This method can drill through glass 1 cm thick in less than one minute.

2. To drill a hole in glass, we recommend taking a triangular file, lowering it into turpentine and carefully drilling a hole.

3. You can also drill glass on a lathe with a copper rod, lubricating it with oil and sprinkling with emery. Special attention should turn to the hole when the drilling process comes to an end and only the last one remains thin layer as the glass can easily crack.

How to make a hole of any diameter in glass.

Glass is thoroughly degreased with acetone, gasoline or alcohol. Then, a handful of slightly moistened fine river sand is poured into the place where the hole will be. After that, a cone-shaped hole is made in the sand crust with a pointed stick to the glass. Its diameter in the lower part of the cone should be equal to the diameter of the hole being made in the glass. Then, molten solder (tretnik or tin) with a melting point of 200-300 ° C is poured into the sand mold. After the solder solidifies, its cone is taken out ... along with the column of glass adhering to it: the hole is ready.

If the glass is poorly degreased, it can burst in any direction and ruin the work.

How to make an attachment for an electric drill
for drilling holes in glass.

Take a diamond or roller from any glass cutter and attach it to a slot in a steel rod. The diameter of the rod should be somewhat smaller than the diameter of the diamond or roller. The roller is attached to the holder with a rivet, and in such a way that it does not have the ability to turn. Then fix such a device on a steel rod in a drill instead of a drill - and you can drill holes in the glass.

The operation of such a device is shown in the figure. "Drill Roller".

Cutting big holes in glass.

To cut a large round hole in glass, you must first drill a small hole in the center, then strengthen one end of the wire in it, and attach a glass cutter or diamond to its other end and cut a circle with it. Then, with a glass cutter or diamond, several radii are drawn along the ruler from the hole to the circle line. After that, they take the glass in their hands and quietly hit the back of the glass with a wooden hammer handle. The cut pieces of glass should fall out. It is desirable to knock out the cut-out parts of glass in water. This reduces the chance of damage to the processed glass.

It is likely that almost everyone has to work with glass. home master. Cutting a sheet of capricious material into pieces is not a particular problem, but the need to drill glass causes difficulties for many. To perform this manipulation, it is possible to contact a specialist whose services are quite expensive, or you can try to do this work yourself. In fact, there is nothing noticeably complicated here, you just need to be careful, because with the slightest deviation from the following recommendations, the surface will become covered with cracks.

It is possible to drill any holes in the glass

Types and features of glass as a material

Glass manufacturing technology is quite complex. A mixture of several components melted at very high temperatures is subjected to rapid cooling, while the crystallization of the material is not completely completed, and it remains amorphous. The type of glass is determined by its main chemical ingredients. There are the following types of glasses:

oxide;
sulfide;
fluoride.

Silicate or oxide material is widely used for the manufacture of a variety of glass containers, including bottles. When melting quartzite, quartz glasses are obtained, sometimes called rock crystal. It is formed when lightning strikes quartz deposits. Glasses can also be classified according to their purpose. So, different kinds glasses can be used to reduce radiation levels, manufacture fiberglass, protect the screens of laptops, tablets and smartphones, as well as in the manufacture of incandescent lamps, kinescopes and x-ray equipment.

Samples different types glass

Depending on the field of application and operational characteristics, glass of different composition can be optical, chemical, medical, protective, window, utensils, and so on. Industrial varieties that are also used in everyday life are divided into several subspecies:

characterized by low melting point and light color potassium-sodium glass;
hard and refractory calcium-potassium material;
expensive and fragile lead glass;
resistant to aggressive chemical environments and temperature differences borosilicate products.

Proper preparation is the key to success

It is quite possible to make an even and neat hole in the glass with your own hands, you just need to properly prepare its surface before performing the manipulation. This is the key to a successful job. The following actions will be required:

grease is removed from the glass, and it is located on a non-slip surface;
the marked location is sealed with a plaster to prevent the cutter from slipping;
the drill when drilling is located strictly vertically;
it is unacceptable to exert strong pressure on the material;
work must be carried out with breaks for cooling.

There are drills for holes of various diameters.

Standard option - use of a drill

Often the task is to drill a small round hole in the aquarium for the aeration tube. To drill at home, the standard option is to use a conventional metal drill. To do the job, you will need a drill with the ability to adjust the speed or a screwdriver.

It is also necessary to prepare a small piece of plasticine and turpentine. A funnel is formed from plasticine, into which turpentine is poured as a cooling working element. The plasticine rim is located around the center of the planned hole.

Careful work guarantees success

Having placed the drill strictly vertically and setting its speed controller to a minimum, they begin to act. When the process is almost finished, but the hole has not yet been completely formed, the glass sheet should be turned over to the other side and continue working from the opposite side to prevent cracking of the material. The final processing of the edges of the resulting through channel is carried out with fine sandpaper rolled into a tube.

Do-it-yourself glass drill

Devices for drilling glass can be made independently. To do this, you must perform the hardening procedure for an ordinary drill. It is clamped with pliers and the cutting end is placed in the flame of a gas burner. When the metal heats up white color, it is cooled in a wax bath. The metal hardened in this way can handle almost any glass material.

This is what homemade glass drills look like

A regular glass cutter can also help. To do this, the cutting element in the form of a diamond roller is fixed on a metal rod in such a way that it is motionless with respect to it. The resulting device can be called a modification of the factory tools with diamond coating.

Making a hole with sand

Before the advent of drills and screwdrivers, holes in capricious material were made with sand. To do this, it was poured in a wet state to the required place and a funnel was formed in the sand, the lower diameter of which exactly corresponded to the cross section of the required through channel.

ancient way make a hole in the glass

Then molten lead or tin was poured into the funnel. After some time, the sand, together with the solidified glass mass, is removed. The hole is perfectly aligned. Its edges do not require further machining. Lead is easily melted by placing it in a mug and directing the flame of a gas burner at it, or simply by placing a metal vessel on a gas stove.

Large hole cut with a glass cutter

A circle large diameter can be cut into glass with a glass cutter. To do this, use the circular design of this tool. It consists of a suction cup located in the center of the diameter, an adjustable tripod and the glass cutter itself. The movement of the glass cutter should be smooth and uniform, and excessive pressure should not be exerted on the handle.

Drilling a large hole in glass

The cut is made once, after which the separation line is tapped from the inside with the handle of the glass cutter. At correct execution all manipulations, the cut fragment is easily separated and falls out into the substituted bucket.

All sorts of different ways to make a hole

It is possible to make a through channel in a glass surface in other ways. For example, you can use ordinary copper wire. First you need to dilute one part of camphor powder in two parts of turpentine, add fine-grained emery and mix the resulting mixture thoroughly. Then apply the composition to the place of work, insert the copper wire into the drill chuck and begin the drilling process.

Large hole can be made homemade drill

You can also do the work using a duralumin, aluminum or copper tube. At the working end of the improvised tool, cutting teeth are cut with a needle file. A wooden cork is driven into the other end, into which a screw with a cut head is screwed to strengthen it in the drill chuck.

On the right place cardboard washers are glued to the material being processed on both sides. The working end of the tube with cutting teeth, moistened with turpentine, is inserted into the washer and glass is produced by one third of the thickness of the material. Then the sheet of glass is turned over, and work continues on the other side until a through hole is obtained.

A hole in the glass will help make a soldering iron

Some craftsmen use a soldering iron to make through holes in a glass sheet. Previously, a marking risk in the form of a ring is applied to the surface of the material. Then the tip of the soldering iron warms up well, and the accurate melting of glass along the segments of the circle begins. Frankly, when using this method, it is rarely possible to obtain sufficiently even edges of the hole.

Before starting any manipulation, it is necessary to thoroughly degrease the surface to be treated. This is done with a rag soaked in gasoline or turpentine. The glass is then thoroughly dried.

It is better to feel the work of the cutter in advance by drilling a few holes in unnecessary pieces of glass. It is important not to create excessive pressure on the working part, even if it feels like the drill is spinning idle, without making the surface of the glass. This is not so: drilling is slowly but surely happening.

In the process of work, it is necessary to perform cooling of the glass surface and the cutting part. Products small size can be drilled in water by lowering them into a container of a suitable volume. In this case, you can not be afraid of overheating.
Cooling the glass during the drilling process ensures a good result

The working point must first be sealed with masking tape and markup should be applied on top of it. This simple action will prevent slipping at the very beginning of the workflow. The drill must be placed vertically, maintaining a strict right angle during the entire time of the manipulation.

It is guaranteed to get rid of the appearance of even small cracks in the material by turning the sheet with the reverse side when choosing a greater thickness of the glass surface.

In addition, this procedure will help reduce the taper of the resulting hole. Accidental cuts on its sharp edges are prevented by grinding the protrusions with fine-grained sandpaper.

Be sure to wear goggles to protect your eyes from the smallest glass fragments in the form of dust. It is necessary to drill thin glass, stepping back from its edge by at least thirteen millimeters. It is necessary to retreat from the edge of thick glass by about twenty-five millimeters, otherwise the material will certainly crack.

When you need to drill a hole in glass, most people will most likely 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 molded 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, you should use a metal container and a 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.

Ordinary glass could well displace from most areas industrial production half of the expensive metals, if not for one of its unfortunate drawbacks - fragility (in other words, extremely low impact resistance). Nevertheless, in hardness it is almost as good as granite, and in strength it surpasses cast iron. Such a set mechanical properties in a complex and leads to the complexity of its drilling. It turns out that creating a neat hole in this hard, but easily cracking material is possible - but not so easy.

Leaving aside special innovative technologies and expensive diamond cutters, consider the most simple and cheap ways how to drill glass so that it does not crack on its own, without the involvement of a master.

Note: safety rules strongly recommend the use of safety goggles - as even the smallest glass fragments can seriously damage the eyes.

Method number 1: Drill with a hardened steel tip

Lay the sheet of glass on a stable and absolutely flat surface.
We mark the centers of future holes (while keeping in mind that minimum distance holes from the edge should not be less than 12-15 mm. for thin glass, and 20-25 mm. - for thicker).
We choose a drill (it can be either electric or manual) and a hardened drill.
Around the place of drilling from putty or plasticine we make and firmly stick a ring with a diameter of 4-5 cm and a height of 1 cm.
In the resulting "pool" pour a little vinegar or turpentine.
We start the drilling process with a little pressure at low speeds (for an electric drill - no more than 300-330 rpm).
For thick glass, we drill only half of the hole, after which we remove the putty and carefully turn the sheet over.
Further, to obtain a full-fledged through hole, we repeat the process on the other side - fixing desired point center, again pressing the ring against the glass and pouring turpentine or vinegar before drilling.
Choose plastic tube slightly smaller in diameter drilled hole, wrap it with fine-grained emery and clean the inner surface.

Method number 2: Drill with a steel non-hardened tip

Obviously, the drill tip will have to be hardened independently. We clamp the drill with pliers and place the tip in the flame from a gas burner (or an open flame if hardening is not done indoors). After changing the color of the steel of the tip to a white heat, cool the drill - ideally in sealing wax or, in the absence of such, in oil. The cooling process is considered complete when the sealing wax stops melting and the oil stops hissing. We clean the remnants of soot and then perform the sequence of operations described in method No. 1.

Method number 3: Drill with a carbide tip

This method is also similar to the first - but the composition of the liquid poured into the ring should be somewhat different: instead of turpentine, you should use its combination with camphor (in a ratio of 1 to 1), and instead of vinegar, aluminum alum dissolved in it in the same proportion.

In addition, it is desirable to cover the surface on which the glass sheet will be placed with a cloth.

Method number 4: In the absence of a drill - with wire and abrasive paste

It is quite possible that the necessary drill will not be at hand at all. Then it will have to be replaced copper wire(for holes of small diameter), which will “help” turn into a full-fledged drilling tool with an abrasive paste consisting of 2 parts of turpentine, 1 part of camphor and large emery grains. The mixture must be thoroughly mixed and filled with a container formed by a ring of plasticine or putty.

After that, the process should repeat p.p. 6 - 9 from the first method.

Method number 5: In the absence of a drill - with a tube and abrasive paste

If the hole diameter is too large for the wire, it is replaced with a tube of the appropriate section. Otherwise, this method copies the previous one (except that the composition of the paste can be replaced with corundum powder dissolved in water).

For glass, it is best to purchase corundum powder grade KP, fraction 180 microns (F80), white. This powder is sold construction stores in the departments of materials for metalworking.

Method number 6: In the absence of a drill - a tube and a screw

This method is an even more complicated version of the use of a duralumin, copper or aluminum tube, from which something like a homemade drill is made.

For this:

We tightly insert a cork made of wood 2-3 cm long into the hollow hole of one of its ends, into which a screw protruding by about 1.5 cm is screwed.
Saw off the head of a securely seated screw.
We cut out the other end of the tube with a 3-sided file so that several teeth are obtained.
We insert the protruding part of the screw into the drill and fix it.
We cut out 2 cardboard washers, with a section along the diameter of the hole, and glue them to the glass on both sides at the drilling site.
We cover the supporting surface on which the glass will lie with rubber (to create greater elasticity), and sprinkle the drilling site with abrasive powder from emery.
The teeth of the tube (playing the role of the drill head) are carefully soaked in turpentine - after which we immediately begin drilling at low speeds until the passage of 1/4 - 1/3 of the hole.
We turn the glass over and repeat the procedure - after which the coup follows again (1 or 2 times until a through hole is drilled).
At the end, we clean up according to the first method.

Method number 7: In the absence of a drill and a drill

The last method (often used when it is necessary to obtain a hole of a sufficiently large diameter) does not use drilling at all. It is produced as follows:

The place where it is necessary to make a hole is carefully degreased (with a rag soaked in acetone, alcohol or gasoline).
We pour fine wet sand on the surface of the glass - in such a way that the diameter of the "slide" (as high as possible) somewhat exceeds the cross section of the future hole.
With a sharply sharpened tube or stick, we carefully make a vertical funnel-shaped hole in the sand to the surface of the glass sheet (making sure that in the end the glass “bottom” that appears is exactly equal to the diameter of the hole and does not contain a single grain of sand).
Melt lead or tin solder and pour it into the funnel.
After 2-3 minutes (when the metal hardens), we completely sweep away the sand and carefully remove the cone.

Since the glass begins to soften and melt already at a temperature of 300 ° C, the glass circle will “stick” to the metal and be pulled out with it - and the resulting hole from the inside does not even have to be processed.

Thus, even without high-quality diamond glass cutters (or even the necessary drill and even the drill itself), it is not so difficult to drill a hole of the required diameter in sheet glass. Although, of course, pre-training is best done not on finished product- but on a piece of glass, whose further use is not planned.

And if you have materials at hand, desire and a little acquired skill, anyone can drill glass so that it does not crack!

If it is necessary to drill glass surfaces, many people prefer to entrust this work to professionals, turn to special services, spend money, and most importantly, time. How to drill glass at home and how you can drill glass, we will learn further.

Varieties and features of glass

The formation of glass occurs during supercooling of the melt from several components, while the rate of this process is quite high and the crystallization process does not have time to complete.

Glass is a fragile material that is often used for human needs. Glass is formed at a fairly high temperature from 200 to 2500 degrees. Not all glasses are transparent, this property is not common characteristic of this material.

In relation to the main material that is used during the manufacture of glass, glasses are distinguished:

oxide,
sulfide,
fluoride.

Depending on the type of application, there are:

quartz type glass - made by melting quartzite or rock crystal, given material it happens naturally, it is formed during a lightning strike at the location of quartz deposits;
optical type glass is used to make lenses or prisms;
high impact resistance chemical substances and temperature fluctuations are characterized by glass of a chemical type;
Industrial glass is widely used in the manufacture of a variety of things that people use.

Industrial glass is:

potassium-sodium type - characterized by a low melting point, it is easily obtained from it different figures, has a clean and light structure;
potassium-calcium type - has high hardness and is difficult to melt, does not have a pronounced luster;
lead type - it is similar to crystal, very fragile and shiny, is more expensive, has a lot of weight, but at the same time is quite soft;
borosilicate type - resistant to temperature changes, foreign substances, rather expensive.

In relation to the scope of use, glasses are distinguished:

window,
tare,
radiation resistant,
fiberglass,
protective,
crockery,
crystal,
thermometric,
heat-resistant,
medical,
heat-resistant,
electroflasks,
electrovacuum,
optical,
chemical,
quartzoid.

Varieties of drills for drilling glass

The process of drilling glass requires a good, and, most importantly, suitable drill and a material that will instantly cool the glass during the drilling process. Consider the main types of drills that are suitable for glass:

a drill in the form of a spear or a feather - made of hard alloys, the diameter of such devices is from 3 to 12 mm, if you have working skills, drilling glass with such a drill is quite possible, but you cannot do without the formation of small chips;
drills in the form of a spear with the presence of diamond coating - they are distinguished by softer drilling, there are no chips;
tubular drill or round type used to cut circles or rings on glass surfaces, this process is most conveniently carried out using a drilling machine;
diamond-coated brass type glass requires mandatory cooling, through the supply of water or turpentine;
a diamond type tubular drill is used to drill a hole in glass, it has the form of a crown with a shank, the end of the crown has a diamond coating, it requires cooling.

Preparing glass for drilling

1. Before you start drilling glass, you should prepare the surface for this process.

2. Using alcohol or turpentine, be sure to degrease the surface, and then wipe with a dry cloth.

3. It is not allowed to slip or shrink the glass sheet on the surface.

4. The glass sheet must be placed on the base.

5. It is better to mark the drilling point with construction tape or a marker.

6. In the absence of skills in working with glass drilling, it is better to practice on small fragments so as not to eventually spoil the material.

7. Drilling glass takes a long time, do not press hard on it to speed up the process.

8. Hold the drill at right angles to the glass surface. Don't drill one hole at a time, stop periodically to let the glass cool down.

9. At the end of drilling, when the hole is almost ready, you should turn the glass over and drill a hole from the back side. This procedure will help to avoid chips or cracks and make a hole of the desired shape.

10. To remove small roughness or irregularities on the glass surface, use fine sandpaper.

How to drill glass with a regular drill

To complete this process, you must have:

drill, which is used for drilling metal or ceramic surfaces;
screwdriver or low-speed drill;
plasticine,
turpentine,
alcohol solution.

The glass must lie on a completely flat surface. Pay attention to the position of the glass, the edges must not overhang and the glass must not wobble.

On a screwdriver or drill, set the minimum rotation speed. Insert the glass and check whether the device breaks the glass, if there is a large runout, it is recommended to replace the drill.

Using cotton wool and alcohol, degrease the glass and make a recess from plasticine in place of the future hole. Pour turpentine into it and start the drilling process. To avoid the appearance of a crack, do not exert great effort during this process. Gently and without pressure, hold the device above the glass.

The minimum revolutions for drilling per minute are 250 and the maximum 1000 cycles.

How to drill glass at home with sand

At a time when there were no screwdrivers and drills used this method glass drilling. In order to drill glass with sand, you will need:

sand,
gasoline,
tin or lead
gas burner,
a metal vessel, preferably a mug.

Be sure to degrease the surface with gasoline, and pour a hill of wet sand into the place of the proposed drilling. Next, using a sharp object, make a funnel of the same size as the hole.

Pour the previously prepared mixture of tin or lead into this form, after a few minutes, remove the sand and remove the frozen part of the glass, which should easily move away from the surface.

To heat lead or tin, use a metal vessel and a gas burner. If there is no gas burner, replace it with an ordinary stove.

Such a hole is perfectly even and does not require additional processing efforts.

How to drill glass with your own hands using a homemade drill

The drill used in the process consists of a diamond roller, which is placed in the simplest glass cutter and a metal rod.

In the rod, you need to cut a special hole into which the diamond roller is placed. The roller is installed in such a way that it is motionless.

Attach the drill to a drill or screwdriver and start drilling.

This drill is a modification of conventional diamond-coated drills, so if it is not possible to buy such a drill, make it yourself.

Another option for manufacturing a drill involves drilling glass, with a small hole diameter of up to 50 mm. Take any ordinary drill. Turn on gas burner, clamp the drill with pliers and hold it over the jet of flame for several minutes. When the tip of the drill turns white, cool it quickly by lowering it into sealing wax. After it cools, remove the drill and remove drops of sealing wax from the surface, if any. This glass has become tempered, and perfectly cope with the drilling of glass.

1. A little honey or turpentine should be applied to the place where the hole will be drilled in order to prevent cracks and splits.

2. Do not press the drill from above.

3. The interval between drillings is 5-10 seconds. It is advisable to dip the drill into a vessel with water during a break to prevent the glass from melting.

4. Do not swing the drill from one side to the other.

5. If possible, it is better to use a screwdriver, this item is more gentle, as it has low speed.

6. The cost of drilling glass in professional setting is from $ 10, therefore, using these tips, you can save a lot of money.

7. Not only alcohol, but also acetone is perfect for degreasing the surface.

8. While working with a drill, do not forget about safety, wear goggles and gloves

9. The distance between the edge of fragile glass must be at least 1.5 cm, for ordinary glass 2.5 cm.

10. The best surface for working with glass is wood.

Working with glass with a glass cutter

1. To make a hole in the glass large sizes or an unusual shape, a glass cutter will do.

2. Using a felt-tip pen or marker, make a markup on which drilling will be carried out.

3. When working with a glass cutter, do not make sudden movements, pressure should be smooth and have the same force.

4. Use the handle of the glass cutter to tap on the glass so that the cut part falls out.

5. To remove excess glass, use special tongs.

6. Pay attention to the condition of the tool before starting work. The location of the roller should be central, it should rotate smoothly and evenly.

Unconventional ways to drill glass

1. To drill carbide type glass, coolant must be prepared. To do this, take acetic acid and dissolve aluminum alum in it. In their absence, mix turpentine with camphor in a ratio of one to one. Treat the glass with one of the solutions, and only then start drilling.

2. If there is no drill, use copper wire to be inserted into the drill. In this case, drilling takes place using a specially prepared solution. One part camphor and two parts turpentine, to this mixture add a coarse-grained type powder from sandpaper. Lay the mixture in the place where you want to drill a hole and start working.

3. There is another way using this solution. Use a metal piece of tubing that should be inserted into the drill. Make a plasticine ring and attach it to the glass surface. The height of the ring is 10 mm and the diameter is 50 mm. In the recess, apply a solution of turpentine, camphor and emery powder.

4. Take a tube made of aluminum, copper or duralumin, the length of which is about 5 cm. Hammer a wooden plug into one end, and cut out the teeth with a hexagonal file into the other. Screw the self-tapping screw into the end on which the wooden plug is located, saw off its head. On the inner and outer parts of the glass, attach two circles previously cut out of cardboard, the diameter of which, such as the diameter of the future hole. Lay the glass on the rubber surface and sprinkle abrasive powder on it. The place where the self-tapping screw is attached, with a cut off head, put it in a drill or a screwdriver, treat the reverse side of the so-called drill with turpentine solution. Drill the third part of the hole on one side, and then turn the glass over and finish the job.
