How to cut glass properly with a glass cutter at home

Glass cutters

The diamond glass cutter was the first to be introduced to the world. It uses a small diamond as the cutting element.

How to Cut Glass Bottles | 3 ways to do it

Among others, this type of glass cutter is considered to be the most productive. Its operating life (run) is more than 10000 m, the maximum thickness of material that can be cut 10 mm.

It consists of a handy handle with a holder, in which the stone is fixed with silver solder. When the working edge of the diamond becomes blunt, it is not replaced, but the other side is turned over. To do this, loosen the screw on the bit holder and turn the cutting assembly by 90°, then retighten the locking screw.

When the second edge is blunted, the diamond is removed and sharpened. Usually it is made on a cast-iron disc with a coating of mastic and diamond dust.

Nowadays stone can be both natural and synthetic. The first is more productive and durable, the second is more affordable and suitable for glass thicknesses not more than 5 mm.

When buying a diamond glass cutter, you should consider its subspecies. There are tools:

  • with a four-sided pyramid for professionals.
  • with curvilinear cutting edge for DIY cutters (SPARTA MATRIX, FIT brands).

After the diamond one, a cheaper carbide roller glass cutter was invented. As its name says, its main working element is a metal roller, and sometimes several rollers (1, 3 or 6 pieces). Working life of such a tool is 350 m, permissible thickness of the material. 1-5 mm. When worn, the rollers are sharpened on a fine abrasive disc or replaced with new ones. This tool is selected according to the number of rollers. The more there are, the deeper the cut and the thicker the glass can be cut.

The next type we will consider oil glass cutter. This is a variation of the roller cutter, the difference being that this tool has the function to supply lubricant to the work piece from the handle, which has a small reservoir. Thanks to this system the friction and the wear of the cutting element is reduced and the productivity is increased. With this cutter you can cut through materials with a thickness of more than 12mm, the service life is up to 5000 m, after which you need a complete replacement of the whole head, because the wear and tear of both the roller and the fixing.

the choice of oil glass cutter is made according to the thickness of the material to be cut according to the angle of sharpening: from 1 to 10 mm. 135; over 10 mm 150. It is also important to consider the type of head. The stationary one is good for straight cuts, the movable one for shaped cuts.

Preparing the glass for cutting

The level of difficulty depends on the condition of the material. So, if you need to obtain finished products from glass that has just been purchased, you do not have to make any special effort. In this case, simply wipe the surface. No need to use special detergents. Use a newspaper to remove stains and dust. This method provides an opportunity to prepare glass surfaces quickly. Do not use a cloth, t. к. there is a risk of lint on the glass surface. The only exception is microfiber.

used glass is prepared more thoroughly:

  • It must be washed using a special glass cleaner;
  • The surface is wiped dry;
  • the last step is to degrease the glass, for this purpose use a rag soaked in kerosene.

Before you start, you need to dry the sheet by leaving it in a closed room. You can additionally cover the material with film so that you don’t have to repeat the cleaning procedure. The preparatory stage also includes cutting the material. If you want to make a circle out of glass or other shaped elements, it is advisable to draw the contours as close to each other as possible. Then the consumption of material will be small. Long elements should be placed along the larger side of the sheet of glass.

How to cut glass without a glass cutter?

The operation is also possible without tools. There are two popular methods.

How To Cut Glass, Without A Glass Cutter? Here Is How

Water and scissors

It should be said right away that this method is only suitable for obtaining rectangular elements. Not any glass is suitable for this method, it can be used only for glass pieces with the maximum thickness of 3 mm. The tool used is ordinary but sharp scissors.

The material is placed in a container with warm water, where the desired shape is cut out. In order not to make a mistake with the size, the glass is glued to the template in advance. Follow the cutting lines with the sharp part of the scissors, then break off unnecessary elements. The thicker the layer of water in the container (over the glass), the easier the work will be.

Water, alcohol and thread

This method gives a chance to “cut off the excess” from almost any figure, but it may not lead to the result the master expects. The operation goes like this:

  • First, they draw on the material with a scythe line. Then the yarn is soaked in alcohol (gasoline), placed on the “borders” and set on fire.
  • The glass with the finishing yarn is lowered into a container with cold water. At this point, it should crack because of the temperature difference.
  • The product is removed from the liquid, it is broken along the lines, and then it is polished with wet sandpaper. A complex figure may “not conquer” the first time, so it is recommended to repeat the operation for such blanks. The main thing in this case is the precise fixation of the threads.

Such work is dangerous because you can negligently burn things in the room. Soldering iron with power of at least 60 W can become the replacement of fire, or the burning tool, but even in this case you need to be careful.

Circumferential cutting of the material

In this case, use a template. The best material for such templates is plywood. Firstly, the glass cutter moves along the mowing line, trying to keep the pressure force equal along the entire length. All other steps (making perpendiculars, removing glass) are carried out in the same way as when working with circles. If we talk about the tool-favorite, then it will be a diamond glass cutter, which does not require a lot of pressure, so the line will turn out more accurate.

Working with “wrong glass

Plexiglas and acrylic products also do not require manipulation with the glass cutter. For materials up to 2 mm thickness, a regular knife can be used for the cut. With thicker sheets can cope hacksaw for metal, hand cutter, angle grinder and three-toothed saw blade. Another contender is an electric jigsaw, which has a speed control function.

How to cut glass without a glass cutter

Some glass-cutting experts advise to cut glass with a woolen thread, which is put or wrapped around the supposed place of cutting glass, then it is moistened with kerosene, and then set on fire. After the thread burns, the glass is dipped into cold water, where it breaks up into the desired halves.

You can try to cut glass with an angle grinder, putting on a fine-grained wheel, but you must do so very carefully, adhering to all safety precautions.

The correct way to cut glass without a glass cutter:

To cut glass without a glass cutter you can take a nail or any sharp object. It’s just that this option will take you a lot longer.

There are also diamond coated ladies’ saws, but they are only good for one time.

After you swipe one of these items on the glass, you need to lightly tap the bottom of the cut.

They say you can cut glass with scissors underwater.

And you can also stick some rope on it, soak it in kerosene, light it and put it in cold water the excess will come off.

True, I have not tried any of the methods myself.

Those are great ways, especially with scissors! 4 years ago

My husband cut glass with an angle grinder, it works, but you need to be very careful and on an even surface.

I used a blowtorch.You just have to be careful.

If the glass is thin, you can easily cut it with ordinary scissors, letting it go into the water beforehand. Two can be cut like butter, I’ve tried it myself. But the three is already difficult to give in, but carefully still cuts. If the glass is molten, then unfortunately you can’t cut it with anything, not even a glass cutter.

Glassware has always been very popular. It is used to make the most beautiful glassware, stained glass, murals, and more. photo). To do all of the above, the material must be cut into different sized pieces. How to do it at home? It is very simple. Glass can be cut in several ways. with glass cutters or without glass cutters using ordinary scissors.

glass, properly, cutter, home

Before considering how you can cut the glass it is necessary to determine what types of glass can be, because this will depend on further action. For example, cutting an ordinary material should not cause almost any difficulties. It can be cut both with a glass cutter and a pair of scissors. But cutting tempered glass at home is not recommended, because it will lose all its properties. It is best to cut it before tempering and then leave this process to professionals.

Fluted glass is most often used for glazing doors or for creating interesting interior elements. You can cut it just like any other material at home, the only difference is that you have to make the cut on the smooth side. It is good, if you have a roller glass cutter handy for working such glass. Organic material can be handled without a glass cutter, using a cutter, a regular saw or other tools. Even a paper knife can do a great job with a glass pane not more than 2 millimeters thick.

First of all, before cutting you should take care of your own safety, protecting your face and hands from splinters. After that you need to prepare the material with your own hands. It is enough to simply wipe the new glass, using for example crumpled newspaper. It is necessary to work a little longer with old material. First of all you should wash it carefully with clean water and a glass cleaner, then degrease it with, for example, alcohol or benzine and dry it well (see the. video).

The way of cutting the material with a glass cutter is quite simple. The main thing is to choose the right tool. For example, you can choose a diamond cutter, like in the photo, which has been the most popular cutter for a long time, or a glass cutter with a slightly beveled cutting edge. The last one can cut the material up to 10 kilometers, after that it should be sharpened on a special bar. The roller tool can consist of 1-6 rollers, which are made of cobalt-tungsten alloy. The oil glass cutter works in almost the same way as the roller cutter, the only difference being that it has an oil reservoir built into the holder, which allows it to cut even coarse material.

So, after selecting the tool, the glass is placed on a flat horizontal surface. On it is made the appropriate marking, which can be created by using an ordinary ruler. After that, by applying equal force along the entire length required, a straight line is made (see “The line”). video). It should be done the first time, as repeated manipulation will lead to cracking of the material.

You can also cut the material with your own hands using regular scissors. For this purpose it is necessary to prepare the scissors themselves, as well as a vessel with hot water. The marking on the surface is made in advance. Next, the sharp side of the scissors is drawn along the marking, creating a small crack, after which the glass is simply broken by hand. Of course, this method of cutting will not be as ideal as the previous one, but it can help in an unexpected situation.

How to choose a glass cutter and cut glass at home without chips and cracks

How to cut glass and what glass cutter to choose. this is what novice homeowners are interested in, when planning a repair in the apartment. Choose a modification depending on the type of glass and its thickness. Focus on the price index, the durability of the device and the resource. the number of meters it can cut through. When working with fragile glass, use tricks that allow you to quickly make a cut with even edges, without chips, scratches, and cracks.

Cutting glass with your own hands is an activity that requires patience and endurance. To evenly cut fragile glass at home with any of the tools, follow the rules:

Trick: To avoid marking out clear glass, put it directly on the drawing and secure it with painter’s tape

Glass cutters are classified by type of cutting part, handle, and purpose. There are diamond, carbide roller and oil models that can cut straight or rounded shapes.

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

A model with a synthetic blade is less expensive than a natural one, but is just as good at cutting. It is designed to cut 10,000 linear meters of glass.

Manufacturers make the cutting head of a diamond glass cutter in one of two forms:

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

On the base of a diamond glass cutter there are 1-3 cuts for breaking glass in addition to the cutter holder. Handle is made of wood or plastic, sometimes rubber inserts are used.

How to cut glass properly with a diamond glass cutter:

Cutting glass with your own hands requires patience and precision. 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 are more durable.

The roller device is easy to use and popular with beginners carvers working at home. Its blade tool, which is in direct contact with the material to be cut, is a tungsten carbide-cobalt roller. When working with glass, it swivels to form a cutting line.

On sale are these types of roller glass cutters:

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

Standard glass cutters are sold in hardware stores and cost about 100. you decide whether to choose a wooden or plastic handle. The set includes five spare rollers to replace.

Movable head allows you to cut curvilinear shapes

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

Kraftool tools are distinguished by their durability. Single wheel model costs 250 and has a service life of 8000 m. Glass cutter with six rollers is cheaper, but each of them is completely worn out in 1000 m. Maximum depth of cut for both tools is 5 mm.

The procedure for cutting glass with your own hands using a roller:

The oil glass cutter is an innovation among glass cutting tools. According to the principle of operation, it resembles a roller cutter, but differs by the presence of an oil reservoir on the handle. A wick runs from the reservoir to the cutting edge and automatically supplies oil to the glass surface. Lubricant performs the following functions:

The oil glass cutter is used for glass 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.

After the oil life is depleted, the entire cutting head is replaced along with the oil seeker roller. They must be replaced:

Rollers with sharpening angles are usually installed:

Cutting head can be either moveable or permanently attached to the base. Some sliding-head tool models have a locking feature for the cutting part.

Due to their ergonomic shape, extensive functionality and reasonable cost, oil glass cutters are more popular than diamond. Always refill reservoir with oil in a timely manner when using such a tool.

Key requirements for glass cutter oil:

  • medium consistency, so that the lubricant 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 passes easily through the wick to the tool blade and leaves a slight viscous residue when pressed. The glass cutting sequence is the same as with the roller cutter.

The devices described above 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 shape cut? If you need to cut a rounded shape, look for a circular tool. In fact, it is an oil analog, fixed on a suction cup.

How to cut glass with a circular glass cutter:

Cutting a circle with a circular tool

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

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

You’d be surprised, but due to the capillary effect, the glass is easy to press. A micro-crack forms on the surface, and then a fracture, and the material falls apart. The quality of the cut with scissors is worse, but for non-responsible openings the method is suitable.

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

Laser machines convert electricity into high-temperature radiation that focuses at a single point. Allow them to perfectly cut the most complex openwork shapes out of glass or mirror without damaging the material.

Advantages of laser equipment: high working speed, waste-free production, perfect cuts. Drawbacks: the need to work in perfect purity, the requirement of professional knowledge to work with the machine.

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. The disadvantage. the impossibility of use in home conditions.

Water-jet cutters act similarly to sandblasters, but water is sprayed instead of sand and air. Specialists set the cutting trajectory on the computer, and then only control the process.

When choosing a glass cutter, consider the structure and properties of the material you plan to cut.

  • regular from 5 mm thickness. cut with a diamond or oil glass cutter;
  • ordinary up to 5 mm thickness. use diamond, roller or oil cutter;
  • hardened. cannot be cut at home;
  • frosted. cut on the smooth side with any tool;
  • acrylic. not glass, use scissors or a utility knife to cut it.

Deciding on the type of tool, choose its category:

Estimate the material thickness adequately. do not skimp on your purchase if you plan to work with glass from 7 mm thick.

How To Cut Glass

Compare the life and cost of each tool:

Pay attention to the angles of sharpening of the blades. the characteristic allows you to determine how thick the tool can work with.

One glass cutter is not enough to cut glass quickly and accurately. You will need other tools:

  • Work table. Its surface must be flat, with no depressions or bulges. Table placed horizontally. Professional tables have metal guides that allow you to move the glass without the risk of being broken.
  • Glass square or ruler with rubber suction cup. If you use professional glass cutters with a ruler, according to which you can set the distance from the suction cup to the cut line, you will hardly need an angle piece. The ruler must be suitable for working with fragile materials and must be fixed with suction cups.
  • A pencil or marker. For marking.
  • Hammer 60-80 g. For tapping out glass that cannot be broken off by hand.
  • Kerosene and cloth. For glass degreasing. Kerosene is also used to fill oil glass cutters.
  • Measuring tape. For measuring.

Ruler with rubber anti-slip lining

There are a number of tricks that you can use when working with a glass cutter. Below are some:

Following the recommendations, you can easily choose the right tool and cope with the time-consuming task of cutting glass.

Safety Techniques

Cutting glass is quite a traumatic process. The main risk factors are three:

  • microscopic glass dust, causing mucous membrane irritation;
  • Small needle-shaped shards that can hurt your eyes when they bounce off;
  • sharp edges of blanks.

Glass cutting, even on a small scale, should always be done with safety glasses and cotton gloves on. If prolonged work on this front is planned, a regular petal respirator would not hurt.

Most injuries occur from exerting too much force on the tool. The chance that your hand with the glass cutter will slip from excessive force is quite high, not only can it cause serious cuts, but it is also guaranteed to ruin the material.

And, of course, the traditional source of injury is human inattention. There’s nothing worse than a glass splinter, so don’t check the quality of cut edges by feel before sanding them and don’t cut glass overhanging or on your knees. Keep your work area tidy, especially on the floor, prefer covered clothing, and don’t set sheets of glass at too steep an angle.

Preparing the glass, tools, and site

Preliminary measures will not be required if you have to cut a completely new material. In this case it is only wiped of dust, it is better to do it with a newspaper, but it is possible and a microfiber. If the glass is already used, the preliminary work will take some time. Carry out several operations:

  • Material is cleaned on both sides with a liquid designed specifically for glass;
  • If another product that does not contain alcohol was used for washing, it is degreased using acetone, kerosene, alcohol, White spirit or Fairy without glycerin in its composition.

Prepared glass is left to dry in a closed room. Some advise to cover the material with foil.

Types of tools

To ensure quality work, it is necessary to buy a good, handy tool. Professional glass cutters are more difficult to work with, but the results are worth it. Those intended for household purposes are not demanding on the handyman, but this unpretentiousness affects the quality of the cut. All varieties of these tools have their own “niche”, because home masters have to cut different kinds of glass: both thin and quite massive.

  • Diamond, professional. These tools have been in use since the century before last. The reason of their popularity is the well-known hardness of the stone (either artificial or real), which guarantees quality of work and long life. With this glass cutter you can relatively easily cut material that has a thickness of 5 (corundum) to 10 mm (real diamond). Its price is rather high, especially in case of real “diamond”. The work will require some skill from the owner, so beginners are better off looking at other contenders.
  • Rollers, Domestic and Budget. Cutting work in them is performed by rollers, which are made of wear proof alloy of tungsten and cobalt (hardened steel). Such glass cutters are able to cut glass up to 4mm thick. This is the best way to get to know your tool. The difference between this tool and a diamond tool is that it is not capable of scratching glass. It pushes it through, so that a shallow groove appears on the surface.
  • Oil but roller glass cutters are the second type of professional glass cutters. They have a reservoir of oil in the handle, it is fed to the cutting assembly, the purpose is to reduce friction, which allows the rollers to penetrate deeper in a shorter time. This tool can easily cut glass up to 8mm thick. Such glass cutters can also achieve results at home.

There is one more kind. a glass cutter-cirk, which cuts circular-shaped parts. Its price is high, because this tool belongs to the professional. Its elements: a cutting roller, a guide ruler and a suction cup, some models have a reservoir for lubrication. It is not practical to buy such a product in a store. For domestic purposes it is assembled by yourself: from a standard glass cutter, a rail and a suction cup.

Any tool should be tested before purchase. Let the salesman do it. If the result is satisfactory, take the glass cutter that has been tested in front of the buyer, as it is possible that others will be found with a defect. a defect in the cutting edge.

Requirements for the workplace

Manipulation with such a vulnerable material requires a certain surface from the master. Otherwise the glass could be scratched, cracked, unevenly chipped and the craftsman could be dangerously injured. Perfect evenness is the first requirement. The table/stool must not have any depressions or bumps.

Stability is a must, because the glass cutter can easily jump off the marked mowing line, resulting in defects. A cloth placed between the glass and the work surface provides the necessary grip. A large terry towel, a bedspread or a sheet can serve as a bedspread. Even an ordinary oilcloth will do.

Breaking

This technological process can be performed in several ways:

Directions for Use Description
Thin workpieces up to 5 mm Hand break the glass (wear gloves to prevent cuts).
The material is thicker than 5 mm Use pliers or wire cutters to bite off a piece of the workpiece. To avoid damaging the material it is recommended to put rubber or plastic tubes on the jaws of the tool.
Thick material and breaking off narrow strips A pencil or similar non-metallic object is placed under the workpiece and then you must press the glass firmly with both hands on both sides.
Large pieces The workpiece is placed so that the cut is 3-5 cm from the edge of the table. Then, holding the half, lying on the table with one hand, the other sharply pressed on the opposite. Be careful as the piece of glass may fall, with this method of breaking it is better to ask for help.

Diamond glass cutter

The diamond glass cutter is capable of cutting glass up to 10 millimeters thick

The diamond glass cutter can be rightly called “flagship” among similar tools. diamond, the toughest material in the world, is used as a cutter in these glass cutters. Due to this diamond glass cutter is able to cut glass up to 10mm thick, and at the same time make the most even cut, almost devoid of chips, and requiring minimal machining. The only disadvantage of a diamond glass cutter is its relatively high cost, even in those cases where not natural but synthetic diamond is used as a cutter.

Working with diamond (or any other glass cutter, for that matter) requires a certain amount of skill.

First of all it is necessary to prepare a surface for glass cutting. For this purpose usual table with some soft things (example carpet or linoleum) will do. The prepared glass is laid on the surface.

It is advisable to test the cutter on an unwanted piece of glass before the main cut. To do this, take the tool with your thumb and forefinger and slide the line across the glass with a little more force than when writing with a ballpoint pen or pencil. If you end up with a thin white line. the cutter is ready to work and you are doing it correctly, but if the line is thick and filled with small glass chips try to change the angle of the cutter.

The actual glass cutting process with the diamond glass cutter looks as follows. Use a ruler and a square to mark out the required lines on the glass. Then on the edge of the same ruler or any flat bar, run the glass cutter with medium force. The white line left over from the glass cutter is aligned with the edge of the table and lightly pressed onto the hanging edge of the glass. If you have done it right, the glass will break off quite easily exactly along the mowing line of the cut.

When working with thick glass (thicker than 2 millimeters) it is advisable to “tap” the saw blade lightly with a hammer before breaking.

If the glass does not break, do not try to make another cut in the same place as the previous one. It is better to shift the marking slightly and perform the entire operation over again.

In order to understand more precisely how to work with the diamond glass cutter, we recommend that you watch the following

Before you cut glass

In the past, both glass and glassworking tools were expensive, and only craftsmen with good skills were able to cut glass, this has changed considerably these days. These days, anyone can do work with glass.

The tool

You need a very good tool to work with glass.

That’s why before you buy and work with glass, you need to start shopping with a tool.

But you should not buy the first tool that comes along, because it can be of poor quality and will not be able to cut the glass as it should.

It is very important to determine which tool you need, because glass cutters come in several types :

Roller

The roller glass cutter has a built-in special roller that is made of a very strong tungsten-cobalt alloy. The normal diameter of the roller is 6,6 mm, this roller diameter allows you to cut glass up to 4 mm thick.

Diamond

The diamond glass cutter is equipped with an appropriately small diamond, this diamond cuts glass. The hardness of diamond is well known, and for this reason it has been used for cutting glass for a very long time.

Oil

Oil glass cutters have recently been added to the list of glass cutters.

This is essentially an improved roller tool, with a reservoir in the handle to supply lubricant to the roller. This grease binds particles that have formed when cutting glass while providing smooth movement. This glass cutter can cut glass up to 20 mm thick.

A couple of tips on buying

  • Before buying any type of glass cutter, it is best to ask the seller to check the tool.
  • If you are satisfied with the tool, you can buy it, but buy the one you have been shown.

It is not recommended to buy unproven tools, as in most cases the cutting edge is defective.
