Disc for cutting glass on an angle grinder

Disc for cutting glass on an angle grinder

In any home, sooner or later, a situation occurs when it is necessary to replace the glass. It rarely happens when you can find the glass sheet you need in size and shape.

Of course, you can use the services of professionals and give them glass to fit the desired size and shape. But this method is quite costly and can take too long. Much easier is to personally study the principle of cutting and perform it yourself.

Instruments

Before cutting, it is worth choosing a tool that will cut the glass. Ideally, a glass cutter is used to cut the sheets. He will do an excellent job with a small amount of work. But if there is no glass cutter, you can always find an alternative to it.

Many people replace the glass cutter with an angle grinder. Replaced at least because the angle grinder is in the arsenal of almost every owner. It is important to remember that you can use an angle grinder when you need to make a small cut in length.

To cut a piece of glass, you need to install a thin diamond disc. Cut only at low speeds. In the future, the principle of operation is as follows:

• Install the disc of the desired thickness.
• Pour water over the glass.
• Make a thin furrow.
• Perform cleavage.

Preparation for the glass cutting process

Prepare carefully before cutting. The main emphasis should be placed on the preparation of the glass itself.

It must be:

If you have new glass, be sure to wipe it with a damp cloth, and then with a dry newspaper. It is better not to use a dry cloth when wiping. it can leave behind particles of lint, which subsequently interfere with the normal operation of the tool.

No new glass needs careful preparation. The glass should be washed with a glass cleaner. Then. thoroughly dry and degrease using kerosene.

Material selection

In order to get a high-quality product as a result, you need to prepare in advance. The glass cutting process will take place without a hitch, if you use only high-quality material.

The main sign that we have high-quality glass in front of us is the green or blue tint of the ends. We strongly recommend that you do not select plates with scratches and minimal chips and sheets with chips as the material. Chipped glass will severely distort the image.

The thickness depends on the size of the frame. If its height and width exceeds 600 mm, the sheet should be approximately 4 mm in size.

Many people are wondering. is it really possible to cut glass with an angle grinder? The answer is unequivocally positive. But at the same time. the work is painstaking and not as easy as it seems. There are many little things to keep track of during the cutting process.

The main one is to monitor the temperature of the glass and not let it heat up. Choose only a good angle grinder to prevent chipping and breaking the glass. It is important to protect the organs of vision and breathing and to prevent the ingress of glass powder into them.

An example of cutting 4 mm glass. In general, it is good to cut thick glass, 4-3 mm. Thinner ones can crack, especially if there is bearing runout (I have strong ones). Under no circumstances should you put pressure on the angle grinder, the disc should only touch the glass. Gently start and finish at the edges.

It is advisable to take a small, ground disc, there are fewer beats.

If you cut a bottle or other thick glass with pressure, then the glass begins to melt like plastic. Don’t forget about safety rules. Bukhankala glasses and protection are required!

Glass is transparent, durable, but relatively fragile. Glass is distinguished by the fact that it tolerates well the effects of almost any temperature, including very high ones. Most often, special tools are used to process it, but if there are none, then you can use other construction tools. A regular angle grinder allows you to cut glass at home. At the same time, glass processing with an angle grinder usually takes very little time, even for a non-professional craftsman.

In order to cut glass with an angle grinder, you will need to use wheels designed for concrete or granite as working attachments. In order for the cut to be of high quality, during the work, it is necessary to regularly water the glass with cold water in the place where the cut is made. This need is due to the fact that the cut zone gets very hot during operation, and too high temperatures contribute to the most rapid wear of the angle grinder disk. Water cooling not only improves cut quality, but also keeps the disc in good condition for as long as possible.

With an angle grinder, you can cut several types of glass. bottle, crystal, regular and borosilicate. Plexiglas differs significantly from ordinary glass in its characteristics. It is a durable yet lightweight material that can be produced in several colors. An angle grinder is used to cut such glass. Only thin circles, no more than 1 mm, can be used as a nozzle. These attachments are commonly used for cutting regular glass as well.

The plexiglass cutting process is also accompanied by a significant increase in temperature in the work area. The appearance of smoke is possible, in some cases the edges of the glass begin to melt. It should be borne in mind that the molten particles begin to scatter to the sides, therefore, special care and accuracy must be shown during cutting. If the safety rules are not followed, these particles contribute to the formation of skin burns. Timely cooling of the section of the circle and the place of cutting of organic glass will avoid such problems, and will also help to perform the cut with the highest quality.

Choosing quality cutting material

In order to obtain a quality glass product for insertion into a frame, it is advisable to prepare carefully. Cutting glass will be more successful if you select high-quality material.

One of the hallmarks of quality glass is the green or blue tint of the ends. In the manufacture of glass, technological inaccuracies are sometimes allowed. as a result, sheets with stripes on them are obtained. You should not use such sheets for insertion into the window. they noticeably distort the images. Do not take scratched glass plates.

As for the thickness of the glass to be cut, it should depend on the size of the frame. With a height and width of less than 600 mm, a sheet with a thickness of 2.5 mm will suffice. If the height or width exceeds this value, the glass sheet should be approximately 4 mm thick.

When glazing at home, a piece of glass should be cut so that it is 3-5 mm smaller than the size of the frame intended for insertion. With the slightest misalignment, glass cannot be inserted into the frame.

Before starting cutting, the glass must be properly prepared. If it is new, wipe the plate with a damp cloth, then with a dry newspaper. Wipe with a dry cloth is not recommended. it can leave lint particles on the surface that can interfere with the movement of the tool when cutting.

If you choose glass that has already been in use, you need to know: it looks much worse and requires more careful preparation. It is necessary to rinse the surfaces by adding special detergents. Then everything must be dried and degreased using kerosene or turpentine for wiping. When drying a sheet of glass, dust must be excluded from it.

How to cut glass with an angle grinder

In any home, glass replacement is sometimes required. Regardless of whether you are going to insert it into a window, door or cabinet, you first need to fit the sheet to size. It is extremely rare to find a ready-made version of a suitable size.

In such cases, you can turn to professional craftsmen for help and pay for their services. But this approach is far from always convenient, since it is quite costly, not only financially, but also in terms of the amount of time spent. Any owner can independently study this issue and cut glass in accordance with their requests.

Tools for the job

Before you start cutting glass, you should decide on which tool to do it. Most often, glass sheets are cut using a special tool. a glass cutter. It is ideal for small workloads. But there are many other tools with which you can adjust the glass to size at home.

For example, many DIYers can successfully cut glass with an angle grinder. Such a tool is in the arsenal of almost every home owner. But it must be borne in mind that for cutting glass, you can use an angle grinder only when you need to make a small cut in length. It is extremely difficult to use the ruler.

To cut a piece of glass with an angle grinder, you will need to install a thin diamond disc on it. Carry out cutting at low speed. This reduces the risk of premature splitting of the glass sheet and the production of glass dust in large quantities.

• Fitting a disc of suitable thickness to the tool.
• The cutting area is slightly moistened. it is better to just pour water on the glass.
• Using a disc, a thin furrow is drawn along the glass.
• Then a chipping is performed along this furrow.

So, to the question of whether it is possible to cut glass with an angle grinder, the answer can be given in the affirmative. But at the same time, it is necessary to monitor various little things during work. In particular, the glass should not be allowed to overheat. for this, you can stock up on liquid for cooling.

RODEX ELECTROPLATED GLASS CUTTER DISC

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

Tool check and workplace arrangement

Before thinking about how to cut glass correctly, you need to decide on the tool that will be used for this specific job. In order to cut a glass sheet with your own hands, a glass cutter is most often used. There are three types of glass cutters:

• roller;
• diamond;
• oil.

The last two are used mostly by professionals. The cheapest and most common option is a glass cutter with replaceable rollers.

Regardless of the model used, it is best to check the sharpening of the glass cutter before cutting the glass. To do this, you can try to cut some unnecessary piece of glass. Ideally, the glass cutter should move with a slight rustle, leaving a thin, continuous line. If it moves with a creak, the cut line is interrupted or looks like a white scratch, then either the cutting element is dull, or mistakes in cutting technique have been made.

It is also necessary to prepare a flat surface, the dimensions of which should exceed the dimensions of the cut sheet. At home, this can be a table covered with a soft cloth. If the table is not large enough, you can put a sheet of plywood or chipboard on top of it. You will also need a marker and tape measure for marking. If the glass will be cut with a glass cutter, then you need to prepare a thick metal ruler. Its thickness should be 8-10 mm. this is the only way to create the necessary stop for the cutting tool.

Sawing dust-free concrete

At construction sites and during home repairs, you often have to cut concrete with an angle grinder. This very dusty procedure is indispensable, especially during the installation of hidden wiring. To do the job, the tool is equipped with solid or segmented diamond discs of various diameters. In this case, the size of the circles depends both on the used model of the power tool and on the required cutting depth.

In order to cut a small unreinforced concrete block without dust or make a strobe, proceed as follows:

• marking the mowing line is applied on the working surface with a construction pencil or marker;
• the marked area with a nearby zone is moistened with water using a spray gun or a brush (even a rag), which is then periodically watered over the cut furrow;
• sawing concrete, regularly removing the disc and cooling it with water.

Cutting concrete using the wet method considered will not completely get rid of dust. This requires constant irrigation.

To cut concrete without generating dust, some craftsmen use a special homemade casing, which is practically sealed. Dust extraction is provided by a vacuum cleaner connected for this purpose.

It is necessary to cut brick, glass, concrete, wood, plywood and other considered materials using personal protective equipment: glasses, respirator or mask, headphones. Clothes with shoes must also be suitable.

The operated angle grinder must be in good working order. You should use high-quality cut-off wheels for sawing, without defects. The discs and the power tool itself must be inspected before work. It is necessary to perform sawing, taking a comfortable, stable position of the body.

It is forbidden to use drugs or alcohol during work. The general state of health should also be normal. The angle grinder should be kept under control at all times, as very serious injury can occur. At the same time, the more powerful the device, the more attentive, neater, and also more careful you need to handle it.

We cut paving slabs, tiled, porcelain stoneware

To cut paving slabs with an angle grinder, you will need a special diamond-cut wheel. Markings are made on the tile, and an incision is made along these markings to almost half the radius of the circle. If an angle grinder with a large circle, then in one pass you can cut the tile at once to the full depth. The main thing is that it should not be larger than the radius of the circle. If the radius of the circle is not enough, then the tile is turned over and a counter cut is made.

Tiles without chips are better processed with a stone cut-off wheel. A fishing line is applied to the tile, along which a contour cut is made. Then the depth gradually increases. When the cut part becomes larger, the tiles are placed on the edge of the table and broken along the mowing line. Irregularities and roughness can be earned later.

Porcelain stoneware works well with stone rounds. Cutting technology is no different from tile cutting technology.

Preparatory stage

When considering how to cut tempered glass, you should consider the preparatory stage. Careful preparation allows you to achieve high quality. Cutting tempered glass at home is carried out taking into account the information below:

Cutting an aquarium in half with a angle grinder ��

• During the production of the material, zones with internal stress areas are formed. With rapid heating and cooling, such areas are redistributed. The inside of the glass becomes more viscous compared to the outer layer.
• At the time of processing, the workpiece must be securely fixed. For this, a wide variety of devices can be used.
• The surface of the tempered glass must be free of contaminants. An example is oils or paints, which can significantly reduce the quality of processing.

In general, we can say that getting ready for work is quite simple. However, without special tools and equipment, cutting will not be possible.

Recommendations for sawing paving slabs and curbs

Paving slabs are a popular material that allows you to beautifully and tastefully arrange paths in the yard or garden. In addition to its attractive appearance, the material is distinguished by its strength, durability, and a wide range. On the sides of the paths, in most cases, a curbstone will be laid, which in its characteristics is similar to the material of the sidewalk.

Often, when laying paths, tiles and borders have to be trimmed to the desired size. For these purposes, various tools are used, one of which is an angle grinder. For efficient sawing, it is recommended to use this power tool with a circle with a diameter of more than 230 mm and a power value equal to or greater than 2 kW. All work is done with a diamond disc.

The cutting of paving slabs and curbs with an angle grinder itself is performed in the same way as when sawing a brick.

• First, markings are applied to the surface of the materials to be sawn using a marker or chalk.
• Check the accuracy of the marking lines by applying a tile or border to the installation site.
• When the size and shape coincide, the construction material is cut without strong pressure on the used power tool.

If the sections contain defects after cutting, then they are eliminated using suitable tools (for example, a hacksaw for metal, a chisel, a file). The circle of the working tool should rotate so that the dust flew in the opposite direction from the working side. At the same time, he must hold the working power tool with both hands, being behind or on the side of it.

The quality of the result and the number of tile cuts depends on the accuracy of the initial marking.

Tiles cut into fragments of the required size should be set aside separately so that dust does not fall on it. For the convenience of subsequent laying, the pieces can be numbered. The still uncut material should be covered with dust, because then it is quite problematic to remove it from the surface of the tile.

How to cut a circle with an angle grinder

Sometimes it is necessary to cut a circle on a sheet of metal, and there is no tool other than an angle grinder. To do this, mark a circle on the selected area with a white marker or thin chalk. the line of the cut should be on the outside of the circle so as not to reduce it.

We install the angle grinder not perpendicular to the sheet, but at an angle. over, the angle grinder will lean towards the center of the circle. At low speed, we make a preliminary contour cut. Both the contour and main cut must be performed in short movements, moving the position of the circle along the contour.

You can do the same when working with other materials. To cut a circle in a tile for a pipe with an angle grinder, you need to make markings on the back of the tile. Then take an angle grinder and make cuts along a chord inside the marked circle at a distance of 4-5 mm from one another.

Then the tile is turned at right angles, and the cuts are made perpendicular to the previous ones. During the cut, pieces of the tile will chip out, but inside the outlined circle. The remaining teeth can be sanded with an angle grinder first from the front side.

Naturally, the cut will turn out obliquely, with an extension towards the back. But this edge can be grasped little by little with pliers and painted over. At the end of the operation, the back side of the hole is ground. This will require accuracy, attention and patience.

How to choose the right glass

Glass masters advise when choosing glass to pay attention to the following points:

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

How else can you cut glass

What if you don’t have a glass cutter at hand? There are ways in which glass is cut with a non-standard tool. This operation can be done with a soldering iron, angle grinder, nichrome thread and even ordinary scissors! Let’s find out how to properly cut glass with your own hands using each of these methods.

• With a soldering iron. First, make cuts with a file at the beginning and end of the cut line. Then, it is necessary to carefully draw it along the entire mowing line with a well-heated soldering iron. Due to the temperature difference on the sides of the surface, the glass will crack, after which it remains only to gently break it off.
• angle grinder. This tool is found in almost every home, so it is not surprising that it was also adapted for working with glass. In order to cut off the glass with an angle grinder, you will need a thin diamond disc. With its help, a thin groove is made along the entire mowing line of the cut, along which a chipping occurs in the future. But when cutting with an angle grinder, make sure that the glass does not overheat, and be sure to use coolant. A good tool is required, otherwise the glass will simply shatter from its vibration. It is imperative to protect the respiratory organs and eyes when working with an angle grinder on glass. The smallest glass dust getting into them will not lead to anything good. Therefore, if you cut a sheet of glass with an angle grinder, you need to stock up on glasses and a respirator.
• Using heating and cooling. A thread impregnated with a combustible substance is laid along the mowing line of the cut and set on fire. Immediately after it goes out, the cut line is cooled with water. The glass will crack from a sharp temperature drop. Another option is to heat the glass with a nichrome thread through which an electric current passes. In this case, no water is required, the temperature difference between the two surfaces of the sheet is sufficient.
• Scissors. Non-thick glass up to 3 mm is cut with ordinary tailor’s scissors, if this operation is performed by immersing the scissors and glass in a container of hot water. Feels like cutting thick cardboard.
