Cutting glass with a glass cutter at home

All existing methods of cutting glass differ from each other by the type of impact on the base of the material.

For example, there is a thermal method that involves heating a certain area of glass.

Also very common is the physical method, which is the impact on the material by brute force.

In industrial production, the waterjet method is usually used, which allows you to process the material with water pressure.

If it is necessary to cut glass by thermal method, a simple cord, matches and flammable liquid (alcohol or acetone will do) will be enough. You may also use an annealing apparatus or blowtorch at home. If you physically work on glass you usually use nails, a pobedite drill, a file, a diamond disc, or simple scissors.

Of course, many of these methods do not allow you to get a perfectly flat cut on the glass. But with some effort and practice, you can achieve excellent results.

Important! When working with glass, you need to remember about safety: you should avoid cuts on the body and contact of shards and dust in the eyes. To do this, use work gloves (thick cloth ones) and safety glasses (bicycle or special).

The file

For the first method you need a file with corners, round tools are not suitable. To cut the glass, you need to make several even, thin strips on it with the tool. It is necessary to press a little harder than medium, and you will end up with a clear shallow strip, as from using a glass cutter. Then simply break the glass against the edge of the table, or do it by placing a match under the cut.

This method is recommended for people who already know how to work with glass. If this kind of work is done for the first time, it is better to try your forces on small glasses beforehand.

Soldering iron

This method is unusual, but takes a lot of time.

It’s great for situations where you need a nice shaped fishing line.

To cut the glass you need a soldering iron (or a pyrometer) and a file.

  • On the glass, draw strips corresponding to the future mowing line of the cut;
  • A small groove is made near the edge with a file;
  • At a distance of 1-2 mm from it, the glass is heated with a soldering iron until a small crack is formed;
  • The same indentation is made from it, and the glass space is heated again with a soldering iron;
  • The action is repeated until the desired break line is completely machined.

To speed up the process, you can sometimes put a wet rag on the glass to cool it down. If an even clear line is needed, a metal ruler can be used.

with an angle grinder

This is a very effective, although rather difficult to use method of cutting glass.

An angle grinder, drill or borer, and a diamond disc thicker than 0.1mm thick.

The glass should be placed on a straight surface to work on. Then take the cutter and guide it with a straight line across the glass surface. It is not necessary to make deep incisions or pass through the glass, it is required to create only a small hollow. Now you can simply break the glass in the marked place with your hands. To prevent chipping and glass dust, you can periodically sprinkle water over the cut area.

Important! This method should not be used by people who are not familiar with the principle of the disk, it requires particular care and precision. Otherwise, pieces of glass can fly off in different directions.

Using scissors in water

This method works on the principle of directional shearing.

It is very easy to cut out figures with smooth round lines, but it is not suitable for creating smooth corners.

To cut it you should take simple scissors and a large bowl (or basin) of water. The liquid will act as a lubricant to make the movement smoother. This method works on glass that is no more than 4 mm thick.

The cutting procedure is very simple. You simply submerge the glass in water and begin to cut around the edges. Water will not allow the material to crack completely, allowing you to control the line of the chipping.

Important! Be sure to wear rubber gloves when working with glass. Otherwise you can cut your hands very badly.

Use a drill bit with a beater

To do the work this way, you need a drill bit with a pobedite end.

It is better to buy a new one, so that there are sharp corners on the head.

The cutting operation looks exactly as if it were done with a glass cutter.

Only push the drill bit a little harder.

Take the drill bit in your hands so that the sharpest edge of the tip touches the material. After a thin cut is formed, the glass can be broken with a scythe line.

With an charcoal pencil

This method is useful if you want to cut out of glass various shapes with smooth edges.

Charcoal pencil can be made at home.

To do this, take charcoal (birch or lime) and grind it into powder.

Then gum arabic is added and mixed. From the resulting pulp make sticks, and well dry them.

First marks are made on the glass and the edges are filed with an emery board. Then a pencil is set on fire on one side, and a scythe is drawn with it. As a result, cracks appear in the glass, which can easily be broken.

Special features for working different kinds of glass

In addition to the usual quartz glass, there are many other types that also find use in the economy and art. True, you can’t cut them the way you can cut ordinary glass.

Tempered glass “stalinite” is obtained as a result of thermal processing, followed by a gradual cooling of the workpiece.

This removes the internal tensions of the substance and makes it stronger.

One annoying thing: tempered glass cannot be cut. Neither the glass cutter nor any other device can cut tempered glass into pieces, as it crumbles to pieces immediately. True, this glass is injury-free: splinters do not have sharp edges.

Acrylic or Plexiglas, also called plexiglass, is not strictly speaking glass. This is a cured acrylic resin, it does not cut like glass. So it can be cut with the same tools as steel or wood. It is usually cut with a fine-toothed hacksaw, and it can also be drilled, sanded, and even bent when heated.

Triplex glass is also extremely difficult to cut. The fact that the two halves of the glass are laminated with a special film, in addition, and filled with adhesive. Some craftsmen say that you can cut and tap two layers of glass in sequence, and then cut the film with the blade. You also have experience cutting laminated glass with a diamond wheel. But the result is always unpredictable, which means that its use can be recommended only at one’s own risk.

You can cut crystal glass just like you can cut ordinary glass. Although the sheets of crystal are much rarer than the bulk products of it. Think about it: isn’t it easier to order the right part already in the right dimensions?

Types of glass cutters and instructions for working with them

Glass cutters are categorized by cutting part, handle, and application. There are diamond, carbide roller and oil models that can cut straight or rounded shapes.

The diamond is durable and sturdy

The glass cutter blade is made of diamond, fixed in the handle with silver solder. The diamond can be:

How to Cut Glass Bottles Perfectly at Home

Cutting without marking

A model with a synthetic blade costs less than a natural one, but it handles the cutting just as well. Capable of cutting 10,000 linear metres of glass.

The cutting head of a diamond glass cutter is made by manufacturers in one of two shapes:

Tools with pyramidal heads are used by professional cutters, and curved tools are used by novice craftsmen at home. When the cutting part of the diamond is blunted, the locking screw of the holder is unscrewed and the tip is slightly turned by another edge, about 90°, and fastened again. After all ribs are worn out, the cutter is replaced with a new one or is sharpened on a diamond-coated cast iron bar.

Provide 1 to 3 notches on the base of the diamond glass cutter to break away the glass, in addition to the cutter holder. Handle is made of wood or plastic, sometimes with rubber inserts.

How to Cut Glass. Beginner Tips

  • Prepare a table with a work surface that is 15% larger than the glass piece.
  • Lay out the ruler and suction cup and additional tools.
  • Wipe the glass with degreaser and mark it with a simple pencil.
  • Holding the glass cutter by its metal base, trace a thin line across the ruler with the diamond blade. Apply substantial pressure.
  • When finished, tap the glass on both sides of the cut with a hammer.
  • Crack the piece so that two parts are formed. The cut must be smooth, with no splinters.

The roller head is popular and simple

Cutting glass with your own hands requires patience and precision from the master. When choosing which glass cutter is better, roller or diamond, make a list of requirements for the tool. If price is the deciding factor for you, choose a model with a roller. Diamond glass cutters are more expensive, but more durable.

The roller cutter is easy to use and is popular with beginner cutters working at home. Its bladed tool, which is in direct contact with the material to be cut, is a roller made of tungsten carbide with cobalt. It will scroll through the glass to form a cutting line.

cutting, glass, cutter, home

There are these types of roller glass cutters on sale:

  • ordinary with a handle made of wood. copes with material up to 5 mm thick;
  • with a plastic handle, made in China. has similar properties;
  • Professional glass cutter. cuts material up to 10 mm thick;
  • Kraftool tools are semi-professional tools.

Glass cutter with 6 rollers

Standard glass cutters are available at hardware stores and cost about 100. Choice of wood or plastic handle is up to you. Includes five spare replacement casters.

  • Unscrew the bolt in the center of the tool.
  • Rotate the roller disc so that a new blade enters the work area.
  • Screw in the screw.

Movable head allows you to cut curved shapes

You can not replace the roller, but sharpen it using a fine-grained abrasive wheel.

Kraftool products are built to last. The single roller model costs 250 and has a service life of 8000 m. Glass cutter with six wheels costs less, but each wheel wears out after 1000 m. The maximum cutting depth for both tools is 5 mm.

Procedure for cutting glass with your own hands using a roller:

  • Make a mark on the glass.
  • Take a ruler from 8 mm thickness and fix it on the glass.
  • Slowly but firmly guide the cutter line.
  • Make sure the tool does not come off the marked mowing line when working.

Oil cutter. with extended service life

The oil glass cutter is a new development amongst glass-cutting tools. similar to the roller glass cutter, but differs in that it has an oil reservoir on the handle. A wick extends from the reservoir to the cutting edge, which automatically delivers oil to the glass surface. The lubricant performs the following functions

the oil glass cutter is used for glass works up to 20 mm thick. It is more convenient to use and easy to move on the surface. tool life 5000 linear meters without sharpening.

cutting, glass, cutter, home

Once the resource is depleted, the working head is replaced in its entirety, along with the roller. To be replaced:

Usually set the rollers with sharpening angles:

There is an oil reservoir inside the handle

The head may be movable or permanently attached to the base. some models of sliding-head tools have a locking feature for the cutting part.

oil glass cutters are more popular than diamond cutters thanks to their ergonomic shape, extensive functions and reasonable price. When using this type of tool, refill the reservoir with liquid grease in a timely manner.

Key requirements that glass cutter oil must meet:

  • medium consistency, so that the grease can easily penetrate through the narrow neck but does not drip;
  • Good adhesion. the oil must not spread over the material surface.

High-quality oil penetrates the tool blade easily at the wick and leaves a thin, viscous residue when pressed. The sequence for cutting glass is the same as with a roller tool.

Circular compass. for circular shapes

The above described tools are appropriate when you need to cut glass in a straight line. But what is the best glass cutter to buy when you need a shaped cut?? If you need to cut a rounded shape, look for a compass-shaped tool. This is essentially an oil counterpart attached to the suction cup.

How to cut glass with a circular glass cutter:

  • Place the glass on the desktop.
  • Attach the suction cup to the center of the future circle.
  • On the “leg” of the glass cutter find the scale.
  • Set the radius of the future circle by moving the head with the blade to the appropriate value.
  • Draw a “foot” circle with light pressure and tap it out gently with a hammer.

Circle cutting with a circular tool

To cut an oval, use a system of two bars, securing them to a suction cup perpendicular to each other, and placing a rod with a cutting tool on top.

Cutters. an unusual solution

If you do not have a glass cutter and buying a tool is not possible, use ordinary tailor scissors instead.

  • Draw the markings on the glass of the mowing line.
  • Heat water in an enameled container until it is warm, but not hot.
  • Dip the glass sheet and the scissors into the water.
  • Make an incision under the water.

You would be surprised, but due to the capillary effect the glass is easy to pressure. A micro-crack forms on the surface, and then the material breaks apart. Cut quality is poorer with scissors, but the method is suitable for non-responsive openings.

Professional commercial installations

Professional glass cutters differ from home hand tools. For large companies, these are automatic machines, powered by electricity. There are three varieties of industrial glass cutters:

Laser glass cutting machine

Laser machines convert electricity into high-temperature, single-point-focused radiation. They allow you to cut the most complicated openwork shapes of glass or mirror with perfect precision, without damaging the material.

Advantages of laser equipment: high speed, waste-free production, perfect cuts. Disadvantages. the need to work in perfect cleanliness, the requirement of professional knowledge to work with the installation.

Sandblasting units create a cut with an air jet mixed with sand and released under high pressure. The advantage of the method is the possibility not only to cut, but also to decorate glass products. Disadvantage. the impossibility of application in home conditions.

Hydroblasting units operate similarly to sandblasting, but water is sprayed instead of sand with air. The experts set the cutting trajectory on the computer, and then only control the process.

How to use the glass cutter. types of tools and features of cutting

This type of tool, such as a glass cutter, is designed to reduce the size of flat glass, as well as adjust it to the appropriate dimensions. The principle of operation of this device is that a scratch is applied to the surface of the glass, along the mowing line of which there is a uniform break.

The construction of the tool is very simple:

  • Handle is a supporting part of the tool. It is made of steel, wood or plastic
  • Instrument head is the working part, which has the shape of a hammer. A cutting element is attached to the head
  • Cutting part or cutter. the base, thanks to which a groove or slot is created

The cutting part is a carbide material that has a diamond coating or is a diamond crystal. There are two types of tool head, movable and stationary. The movable head allows the mowing line curves to be cut according to the template. Cutting element is mounted to the head by means of silver solder. The cutter is available in three different forms:

  • In the form of a four-sided regular pyramid. the angle of the cutting edge in relation to the holder should not be more than 30 degrees
  • Curvilinear design. the straight projection of the edge has a tolerance of 0,015 mm
  • The roller is the most popular type of cutting element, which is popular in the household

Glass cutters according to the principle of operation are divided into types. The simplest and cheapest tools are the roller type. The most expensive are considered to be diamond models, which have a diamond cutter. We will find out more about what kinds of glass cutters there are next.

How to properly cut glass at home with and without the glass cutter

Experienced craftsmen recommend using the three main types of glass cutters, with which you can easily cut the glass to the required dimensions, even at home.


Quite a popular model, which is notable for its ease of use. Glass cutter roller is very often chosen by beginners, because it is characterized by convenience in the work. In addition, such a tool is cheap because there are no diamond stones in its construction.

Structurally, the glass cutter consists of a roller part and a handle. Special hard alloys are used to manufacture the roller, the element is 5 mm in diameter.

But the working resource of such a tool is limited, because it is enough for three and a half to four hundred meters of glass material. But since it is very reasonably priced, you can buy a new tool at any time. In addition, the package includes several removable roller elements, so you do not have to change the purchased tool for quite a long time.


Another common, effective and popular glass cutter is the diamond. This variant is perfectly suited for both professionals and inexperienced glass cutters.

Let’s see how to cut glass with a diamond glass cutter. Let’s notice at once that during the learning process you will spoil more than one dozen glasses, but all your expectations will be justified, once you master the technique of diamond glass cutter.

Diamond glass cutter

The tool consists of a handle and a working head with a diamond element, which can be pyramidal or beveled. All should be aware of this peculiarity, because the shape differences of the heads influence the working principle. For example, it is much more difficult to cut glass with a pyramid-shaped head. it requires a developed, almost “musical” ear. Let’s see how to cut glass with such a cutter. The diamond moves on the glass surface and makes a certain frequency sound. When the sound is “wrong”, it confirms that the movement of the diamond element is not correct, and the glass chip is very likely to be defective. Beginners use a glass cutter with a beveled head to cut the shape correctly.

The stone in such a tool is either artificial or real, and this difference influences its cost. But there is one more peculiarity: a real diamond can cut a centimeter-thick glass, while a synthetic one is enough only for 5 mm. Yes, and the operating period of such samples is different. a real diamond will cut ten to fifteen kilometers of glass, while an artificial diamond will finish its operation after the fifth kilometer.

Oil cutter

This glass cutter variant is an improvement on the roller head tool. There is a small reservoir in the handle where the cutting fluid is poured. During cutting, it is constantly fed to the roller and glass surface, greatly reducing friction and improving the quality of the scratched lines, ensuring a long service life of the tool. In the end, the service life of the oil glass cutter, compared to a simple roller cutter, is increased fifteenfold.

Oil glass cutter

In addition to the models mentioned above, there are also circular glass cutters that can easily cut circular holes in the glass. Such tool is a bit different by design, resembling more circular than a handle with a cutting element. In addition to circles, this glass cutter can also cut ellipse-shaped holes.

When working with such a fragile and sometimes sharp material, the first thing to take care of is the work area where the cutting itself will be done. It is necessary to get a table with a flat horizontal surface, so that it was without any differences. It will be more convenient to perform these actions if you cover the table with a blanket.

Glass cutting with the glass cutter: the necessary tools.

To perform such manipulations, you will need a certain set of tools:

  • Glass cutter, because we directly cut with a glass cutter;
  • a ruler to measure the necessary size of the glass;
  • angle piece;
  • a marker or marker pen to make marks.

How to cut glass properly with a glass cutter?

To get a good result, it is worth saying a few words about how to cut with a glass cutter, how to hold it correctly in your hand.

Among experienced glass cutters, you can find two techniques for using such tools:

How to cut glass properly with a glass cutter?

There is no difference in hand positioning when using this tool. You decide for yourself how you want to use the glass cutter. And for craftsmen, it’s just a matter of habit.

How to use the glass cutter?

To begin with, a very convenient way to work with such a tool is to run it on a ruler. That way the scratch is going to be straight, without any bends. The edge of the tool should be sharp, because it is this characteristic that determines the scratch on which the glass will break off further.

The cut should be thin and even along its entire length. If it turns out to be wide and has a whitish tint, then this situation can be reasoned as a low-quality, blunted edge of the tool. Also insufficient force applied to the tool can be the cause of this problem.

How to cut with a glass cutter: in one go or is it worth it to spend several times with the tool on the glass?

This situation is a frequent problem with beginner glass cutters. Since it is considered a big mistake to run several times over the surface of the glass. A single scratch should be made with the same amount of force applied to the glass cutter. Deformation of the glass surface can occur. Such a problem can be influenced by:

How to cut and break glass with a glass cutter?

Breaking glass is another important step in cutting. After all, the integrity of the material and the quality of the cut depends on exactly how it is done.

Such manipulation can take place using your hands directly, tapping the tool on the back of the material. If there is a situation with a change in the direction of the break, this can be corrected with pliers or a notch on the glass cutter itself.

If you follow all of these points, you should be able to do the job without any problems.

How to cut with a glass cutter safely?

Safety precautions are of no small importance when working with glass and glass cutters.

To understand how to cut glass with a glass cutter and not to harm your health, it is worth to understand what exactly is dangerous for such an activity. Glass can cut your hands, a fallen piece of glass can also hurt your feet, and even get into your eye. These consequences can cause a lot of damage to your health. It is therefore necessary to wear thick clothing that covers the entire body surface, to use gloves on the hands, to use closed shoes, and always work in protective glasses.

All tools for cutting and breaking glass at bargain you will find in our online store. Step into the catalog and place your order.

What must be taken into account when working?

As in every business, there are some nuances to consider when cutting a mirror at home. Before you start work you will need to read the advice of professionals and learn the technology of cutting. All of this will help you better understand the process and prevent or reduce mirror deterioration.

You should be aware of such important trivia:

  • the tool must be kept perpendicular to the surface during cutting, a minimal deviation of a few degrees is allowed;
  • the table to support the glass must stand flat and firmly;
  • the cut must be made in one precise, quick and continuous movement;
  • It is highly recommended not to change the pressure during the cutting process, only about half a centimeter before the edge of the mirror you can loosen the pressure to avoid chipping;
  • the glass is cut from the far edge towards itself;
  • The cut is made only on the front side of the mirror;
  • when using a roller glass cutter, if the cut is made qualitatively, then there will be a dark trace on the mirror, if the mowing line is whitish, then most likely, the glass is not cut completely;
  • if a diamond glass cutter is used, the trace on the mirror will always be white;
  • When using a long ruler, you can put pieces of bicycle inner tubes on the edges of the ruler to prevent it from sliding.

A very important addition. In no case you must not deepen badly made cut, because you will not be able to repeat it exactly, and the following steps will only lead to the fact that the mirror will be spoiled and it will be possible to cut out of it only a smaller element.

Cutting glass at home: with the glass cutter and simple scissors

Products made of glass at all times have enjoyed great popularity: frescoes, stained glass, dishes, and many other things created from scraps of this material, always struck people with its elegance and smoothness of lines. Looking at this magnificence, it seems that in order to create it one must be a real professional having great experience in working with glass and a lot of necessary tools, but a mere “mortal” will never master this difficult science. In fact, not everything is as sad as it seems at first glance, and everyone can get the knowledge of how to cut glass at home.

The glass must be held securely in place so that it does not move in the process. After the cut is made, you need to shift the material so that the part that is not needed hangs in the air and push it down.

IMPORTANT. Do not use a hammer to separate the unwanted part of the material. Thus, the piece can crack or break completely.

Hold the tool at an angle to the glass during cutting. Try to make the cut in one continuous line.

You need to move the glass so that the part that is not needed is hanging in the air and push it down. You can lightly tap the handle of the tool, it is made in such a way that it will not cause destruction of the material.

IMPORTANT. The cut line should hang down about 1-2 centimeters away from the table surface.

The hanging part should be supported by hand during the tapping. The vibration should break the material. If this does not happen, you will have to repeat the cut on the same marking and press by hand.
