Is it possible to cut the glass with a corner grinder. Rules for the use of corner grinder in the processing of various materials

Cutting glass corner grinder with a diamond disk. How to cut a corner grinding

Glass is considered one of the most common materials. To increase its strength, hardening technology is used. After such a procedure, the degree of processing of the material is significantly reduced. When considering whether it is possible to cut hot glass, we note that only with the use of special technologies can the appearance of a defect be avoided. Today, cutting of hot glass can be carried out at home, for which a variety of tools are used.

Before starting work, you need to prepare the glass itself: rinse it with water, degrease with gasoline. If it will be mounted in a frame, you will have to fit the product to the right size. In this case, on each side you need to additionally cut off 2 mm of the material. This applies only to wooden frames, since with atmospheric influences they can compress and expand.

Glass Grinders & Maintenance

Before cutting off the glass, you need to prepare the space. To work with it you will need a table or any stand. This will facilitate cutting and help to break the product even more evenly. If the master has to cut the material for the first time, then he should practice in small pieces to understand the basic principles. Only then can you proceed to the cutting of large sheets.

How to choose the right glass

Grace masters are advised to pay attention to the following points when choosing glass:

  • The scratched sheets should not be used.
  • If all the rules are not observed in the process of rolling glass or cooling, then such sheets may have defects in the form of strips. These stripes will significantly distort the image, so it is better not to use such sheets to replace glass in the window.
  • The thickness of the glass depends on the size of the frame into which it is inserted. If its width and height are less than 600 mm, then you can do with glass 2–2.5 mm thick. And if one of these parameters exceeds 600 mm, then the thickness of the glass sheet increases to 3.5–4 mm.
  • When performing glazing at home, you need to cut off a piece of glass 3-5 mm less than the size of the frame, because its slightest skew will not allow you to insert glass into the opening.

The second method

In a more complex, but in a much effective way to reduce the amount of dust when cutting corner grinding of an organic density, is the use of a construction or household vacuum cleaner.

In this case, it is necessary to have either a special device that, when cutting a plexiglass by sucking the produced particles, makes work with the material safe, or, again, use improvised means.

The easiest way to independently take a polyethylene pipe and use tape to build a pipe sucking in a vacuum cleaner. In this case, you can use plumbing PVC pipes and components that are sold to them.


Before the most sharp, it is worth choosing a tool that will cut glass. Ideally, glass cutter is used to cut the sheets. He will perfectly cope with the task, subject to a small amount of work. But if there is no glass cutter, you can always find an alternative to him.

Many replace the glass cutter with a corner grinder. Replace at least because the angular grinder is available in the arsenal almost every owner. It is important to remember that you can use an angular grinder when it is necessary to make a small section in length.

Basic safety regulations

Before cutting a tree, it is necessary to familiarize yourself with the safety regulations before the corner grinder. The main of these rules is as follows:

  • Be sure to use personal protective equipment (protective plastic glasses, fabric gloves), work in overalls.
  • It is strictly forbidden to use disks having defects.
  • It is recommended to hold the corner grinder hard with 2 hands.
  • Constantly ensure that the electric cord is not near the rotating disk.
  • Put an angular grinder only after a complete stop of the cutting element.
  • Do not clean the protective casing.
  • Do not work intoxicated.

You can not use equipment that is not intended for work with angular grinder. Cutting equipment for a disc circuit saw should not be used for the following objective reasons:

  • The corner grinder has a higher rotation speed than the circular saw. The disk is designed for lower speeds, so at high speed it, cracked, can fly apart. Flying fragments can harm health.
  • The tree has a more viscous texture and inclusion in the form of knots, because of this, the teeth enter the material unevenly. If the disk is jammed, the tool can be pulled out of the hands, which is fraught with dangerous injuries.
  • Due to the uneven loads, the equipment is overheated and failure is possible.

How to cut a mirror without glass cutter

The mirrors surrounding us: in a car, a bathroom or a female cosmetic bag, are in their structure an ordinary glass with a layer of metal on the back surface. Cutting glass with a mirror coating practically does not differ from the usual one and can be performed by a regular glass cutter or the methods given above. When there is no special tool at hand, the most effective device for cutting will be a file or a diamond disk. Let’s take a closer look at how to cut the mirror at home without glass cutter, using improvised means.

First of all, it is necessary to prepare the processed surface: wash, degrease and dry. The mirror should be clean, without spots and strong stains. Otherwise, the fishing line for the trimmer cut can lead and the chip will be uneven. The working surface where cutting will be carried out should be even and not very stiff. You can lay a dense fabric or a piece of linoleum on the table.

Having prepared the material and the workplace, we mark the fishing line for the trimmer of the future cut on the mirror. Straight lines are better to drive along a ruler or a rail with a height of at least 5 mm. So that the emphasis does not slide, to its lower part you can glue the strip of island. Next, take a file, corner grinder or other tool and make a cut along the marked line. A more detailed process of various cutting methods, scheduled above.

When the cut is ready, it remains to break the mirror in the right place. To do this, you can put a small item (match, pencil, nail) under the fishing line for a trimmer for a trimmer) and slightly press on two sides. You can put glass on the edge of the table or carefully tap from below a small metal object (drill or spoon). If the glass does not break, you do not need to crush very much. It is better to make a second cut in a couple of centimeters from the first.

The above methods have the right to life and give out a good result with skillful handling of glass. Perhaps without experience in glass work, getting an even chip the first time does not work. Before proceeding with the processing of the main material, we recommend that you first fill your hand on unnecessary fragments. If you want to get high.Quality cut without prolonged practice, it will be better to purchase roller or oil windows.

Cutting wood, plywood, laminate using angular grinder

To cut a tree, plywood or laminate with a corner grinding machine, the corresponding discs are used. They are designed specifically for working at high speeds. But the best.Suitable circles on sale are quite rare.

Cutting wood

A special wood disk has side teeth, increasing the size of the cut. In any case, it is necessary to cut wood carefully. The thickness of the boards should not exceed 4 cm.

Cutting wood with a corner grinder is a very unsafe occupation, during which you can easily get an injury. At the same time, it is strictly forbidden to use circles from the circular saw, because they are designed to work at a speed that does not exceed 3,000 rpm. If jamming occurs, then such circles may collapse. This is due to the fact that they make them from solid, but relatively fragile steel. Also, you should not use nozzles with large teeth, because the probability that the teeth will hook, and the circle will jam. In this case, the probability of pulling out the power tool from the hands increases repeatedly.

If, despite the increased danger, it is decided to saw boards with a corner grinding machine, then you must adhere to the following recommendations.

In order to best protect the workflow, the angular grinder should be used as a circular saw fixed in a stationary (motionless) position. In this case, the tool is fixed on a bed with guides. During sawing, the working material is served in the same way as on the circular.

The main disadvantage of this method of cutting lumber is the relative complexity of its implementation from a technical point of view.

Cutting laminate and plywood

To cut the laminate, use metal circles, concrete designed to cut ceramic tiles, as well as fine.Tooth wood. When working, it is recommended to adhere to the following rules:

  • The cut should be performed from the front part of the lamellas so as not to leave chips at the place of the cut;
  • Due to the formation of a large amount of dust and the appearance of an unpleasant smell of burning material, you need to work in a well-ventilated room;
  • To obtain an even cut, the lamella must be motionless.

To saw plywood, use wood discs. The cut is performed according to the previously marked line. At the same time, you should make sure that the circle does not jam the sawed fragment of the sheet before the end.

Work tools

Before starting cutting glass, you should decide on which tool to do this. Most often cut glass sheets using a special tool. Glass cutter. It is ideal for small in volume of working tasks. But there are many other tools with which you can adjust the glass at home in size.

For example, many home masters can successfully cut glass with a corner grinder. Such a tool is in the arsenal of almost every owner of the house. But it must be borne in mind that to cut the glasses, you can use a corner grinder only when you need to make a small section in length. The use of the ruler is extremely difficult.

To cut off the part of the glass with a corner grinder, it will need to install a thin diamond disk on it. Cutting at low speeds. So it is possible to reduce the risks of premature cracking of the glass sheet and obtaining glass dust in large quantities.

  • A disk of suitable thickness on the tool is installed.
  • The saw area is slightly moisturized. It is better to simply pour water with water.
  • With the help of a disk on the glass, a thin furrow is carried out.
  • Then a chip is performed on this furrow.

So, when asked if it is possible to cut glass with a corner grinder, the answer can be given a positive. But at the same time it is necessary to monitor during work of various trifles. In particular, glass overheating should not be allowed. For this you can stock up with liquid for cooling.

For cutting glass, you need to choose only a high.Quality tool. Otherwise from vibration during operation, glass may fly. Before work, try to protect the organs of vision and breathing well so that glass powder does not get into them.

How to cut glass without glass cutter: step.By.Step instructions, methods and recommendations

From the glass canvas you can get different in the shape of the design, but for this you need to learn how to trim it. If there is glass cutter, then this task can be easily handled. And if he is not? How to cut glass without glass cutter? In fact, there are several ways to cut material using various devices, which will be discussed below.

Preparation for work

Before starting work, you need to prepare the glass itself: rinse it with water, degrease with gasoline. If it will be mounted in a frame, you will have to fit the product to the right size. In this case, on each side you need to additionally cut off 2 mm of the material. This applies only to wooden frames, since with atmospheric influences they can compress and expand.

Before cutting off the glass, you need to prepare the space. To work with it you will need a table or any stand. This will facilitate cutting and help to break the product even more evenly. If the master has to cut the material for the first time, then he should practice in small pieces to understand the basic principles. Only then can you proceed to the cutting of large sheets.

Cutting glass cutter

Before using improvised tools, you need to understand how to cut glass with glass cutter. The cutting element is located perpendicular to the surface and strictly along the intended line.

Best way to cut plaster clean, and not with an angle grinder!

They slightly press the tool and carefully begin to lead “on themselves”. If everything is done according to the rules, the sound of the cut glass will be heard and a thin white fishing line for a trimmer on the sheet will appear.

The creak when cutting indicates the incorrect inclination of the tool, its breakdown or too strongly pressing.

After cutting the glass cutter, the glass is placed on the edge of the table (or stool) so that the resulting fishing line for the trimmer is slightly visited by its edge. With one hand you need to hold the sheet, and pressed on the hanging part (it should fall off). If you can’t hand it, then you can carefully tap with a hammer along the line line. If necessary, the process is repeated from the very beginning.

We use scissors

Not very thick material can be cut with ordinary scissors. First you have to mark.

How to cut glass in this way? You need to immerse it in warm water and cut it into pieces of the required size.

If nothing happened or the material began to crumble, it means that the hardened glass came across (the cutting features are indicated below). For cutting a large piece you will need a bath or a large basin with water.

The procedure is performed as follows: the scissors are spaced according to the marking, after which the unnecessary element is broken off. This method is suitable for sheets up to 3 mm thick and allows you to cut figures with straight circuits. To facilitate work from cardboard, a template is made, which is glued with glue to the workpiece. You should know that the material will be more supple under a large layer of water.

The method described below will tell you how to cut off the glass evenly if there is no glass cutter at hand. Everyone knows that the material is afraid of sudden temperature differences. This property can be used to cut it. For work, you will need: twine with a thickness of a maximum of 2 mm (only from cotton), lighter, gasoline (kerosene).

The glass sheet is laid on the table and marked a fishing line for a trimmer, according to which you need to cut it. Measure and cut off the twine so that it closes the entire cut along the length. After that it is watered with gasoline and applied to the line on the glass.

The twine must be set fire so that it caught fire along the entire length. When the thread goes out, it is watered with cold water. As a result, the glass will crack at the temperature difference.

If the crack has not passed through the entire sheet, then you need to repeat the procedure and slightly tap along the cut line.

We work as a soldering iron

How to cut off glass if there is a soldering iron at hand? The material is placed on a flat surface and with the help of a superstil, risks are made at the edges. A ruler is applied to it and touched with a soldering iron with an indent from it by 2-3 mm. It is necessary to warm up each place so that the glass cracked. The soldering iron passes throughout the cut. So it will turn out quite even.

Break the glass with special forceps or laid on the edge of the table. The break will pass exactly along the furrow when gluing along the cut with a sticky tape or a wet newspaper. If the product needs to be inserted into the frame, then you will have to cover the installation site with a gloss or strips of rubber. It is applied to the frame and closed with stacks, under which the rubber seal is placed.

Cutting with a coal pencil

Below we will talk about how to correctly cut off the glass with a coal pencil (you can do it yourself). It allows you to cut various figures from the material.

For the manufacture of the tool you will need: charcoal (linden, birch) and hummiarabic. Coal is grinded into powder, a hummiarabic is added to it and a kind of dough is kneaded.

Round sticks are made from the mass, after which they are thoroughly dried.

Before the cut on the glass, marking and the edges are tied with a file. The pencil is set on fire on one side and lead it along the line. The result is cracks in which the product easily breaks.

Cutting different types of glasses

When cutting ordinary glass, there should be no problems. Various tools will help to cope with this task: from scissors to special glass cutters. But how to cut off a hot glass? This is exactly what will be discussed below. At home, you can also cut organic and corrugated glass.

Calcated products are in great demand, since they are inserted into the doors and various interior structures. This material is easy to cut (like ordinary glass), so you can use the above tools. It should be remembered that the cut should be performed on the smooth side.

How to cut hardened glass? In fact, such a product cannot be cut at home. Work is best entrusted to professionals who have a machine with a diamond circle.

A special emulsion is necessarily supplied to it, which is responsible for cooling the surface.

You can, of course, try to cut the glass with glass cutter or corner grinder, but even with a slight deviation from the flat line, it will begin to crumble.
