DIY round glass cut

Glass cutting sequence

To properly cut the glass with a glass cutter, you need to carry out a set of preparatory measures:

  • Finding a convenient place for slicing. A writing desk or other flat surface will do;
  • Cleaning glass from dirt, dust and other foreign materials;
  • Preparation of protective equipment. gloves, goggles, and a waste box.

Caution! During cutting, the glass should not vibrate or vibrate, its surface should closely adhere to the working area.

Cutting glass with a diamond glass cutter is like a drawing lesson in school. It is enough to take a ruler or template, attach it to the glass and draw the desired line along them with a working tool. After that, a shallow, barely noticeable trace will remain on the surface of the material. The process itself should be accompanied by a light crackling sound.

In order for the work to be done efficiently, you should adhere to some recommendations:

  • At a distance of 3-5mm from the edge of the glass, it is necessary to reduce the pressure on the tool in order to maintain its edge;
  • The cutting tool is extremely sharp, so you don’t need to press too hard on it. This way you can get a deep cut with convex edges;
  • Keep the line running time to a minimum. A one-meter piece of glass is cut in 2 seconds;
  • Under no circumstances should a new cut be made along the same mowing line.

After laying the mowing line, you need to divide the solid sheet of glass into two parts. This is done by tapping the cutter’s handle on the made mowing line. To do this, you first need to slip a piece of glass to the edge of the table, so that the line is at its end, and gently knock along its entire length. You just have to hold the second piece of glass sheet with your hand so that it does not fall.

Caution! For those who will be engaged in glass cutting for the first time, it is recommended to “practice” on waste and other pieces in order to gain experience and feel the intricacies of working with the tool. In most cases, this is sufficient to avoid unforeseen situations and unwanted losses in the future.

Glass is inherently extremely fragile and must be handled with extreme caution. In order not to receive additional losses during its cutting, you need to use the tools correctly and adhere to the appropriate working technique. First of all, you should familiarize yourself with the cutting device itself.

Choosing a glass cutter

Each glass operation requires a specific type of cutting tool. There are three main types of glass cutters:

Diamond glass cutters can work with workpieces up to 10mm thick. Their main element is a small natural diamond securely fixed inside a special holder with a wooden handle. Small holes are provided for breaking off individual pieces of glass.

Caution! In cheap glass cutters, artificial diamonds are installed, which are slightly inferior in strength to natural ones and can work with material no more than 5 mm thick.

Roller glass cutter works thanks to a durable tip with a metal roller made of tungsten cobalt alloy.

An oil glass cutter works on the same principle as a roller glass cutter, however, a special oil is supplied to the tip from a reservoir on the holder to reduce friction and thereby increase the life of the device.

Making holes in glass

There is an ancient, but something now forgotten method of making holes in glass. The space on the glass, where the hole should be, is properly cleaned of dirt and grease with gasoline, acetone or alcohol. Next, moist fine sand is poured onto the washed place and a funnel is made in the sand to the glass with a sharpened stick of the required diameter. Molten solder (lead or tin is acceptable) is poured into the form prepared in this way in the sand. After 1-2 minutes, the sand should be discarded and the solder cone removed. A smooth through hole appears in the glass.

One of the fragile materials is glass, which must be handled with great care. To carefully drill a hole in the glass without cracking it, you should follow the recommendations, carefully select the tools for work.

How to make a hole without drilling

If you do not have the right drill and drill at hand, then there is another way to make a hole in the material. You can use the old method. You must have with you:

  • Sand.
  • Tin (or lead).
  • Any thin and long object (you can take a wooden stick with a pointed end).

Work begins with degreasing the glass, onto which a small pile of wet sand is poured. A small funnel is made in it with a sharp object. Deepening is made to the surface of the glass. The center of the funnel should match the diameter of the future hole. Then a mixture of tin or lead (called solder) is melted and poured into a funnel.

After a few minutes, the sand is removed. The frozen metal is obtained, at the end of which there will be frozen glass. It should peel off easily from the surface. The result is a perfectly straight through hole in the glass.

Standard Option. Using a Drill

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

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

Careful work guarantees success

Having placed the drill strictly vertically and having set its speed regulator to a minimum, they begin to act. When the process is almost complete, but the hole has not yet been completely formed, the glass sheet should be turned over to the other side and work continued on the opposite side to prevent cracking of the material. The final processing of the edges of the resulting through channel is carried out with fine emery paper rolled into a tube.

A drill for glass can be made by hand

Devices for drilling glass can be made by yourself. To do this, it is necessary to perform the hardening procedure for an ordinary drill. It is clamped with pliers and the cutting end is placed in the flame of a gas burner. When the metal is white hot, it is cooled in a wax bath. Metal hardened in this way can handle almost any glass material.

This is what homemade glass drills look like.

A regular glass cutter can also help. For this, the cutting element in the form of a diamond roller is fixed on a metal rod in such a way that it is stationary in relation to it. The resulting device can be called a modification of the factory diamond-coated toolkit.

Drilling a large hole in glass

The drill is made from a piece of aluminum, duralumin or copper tube 40-60 mm long. From the first end, a wood cork is hammered into it to a depth of 20-25 millimeters, and at the other end, the teeth are cut out with a triangular file. A small screw 4-5 mm thick is screwed into the cork so that its smooth part protrudes 10-15 mm. The head is sawed off. They are glued to the glass on both sides along a paper washer with a hole equal to the diameter to be drilled. The glass is placed on a piece of rubber. A little abrasive powder is poured onto the drilling space. Then insert the end of the screw protruding from the cork into a hand drill, lubricate the teeth with turpentine and then start drilling. When the tube goes deep into the glass by at least 1/3 of its thickness, turn the glass over and finish drilling on the second side.

Helpful hints

  • To avoid cracks and chips, it is recommended to apply a small amount of honey or turpentine to the area where the hole will be made.
  • When drilling, take short pauses of 5-10 seconds. At the same time, immerse the drill in cool water to enhance the effect, otherwise it may melt.
  • Do not swing the instrument in different directions.
  • You can use acetone instead of alcohol.
  • When working, do not forget about safety precautions: use protective glasses and gloves.
  • The hole should be located at least one and a half millimeters from the end of the glass sheet.
  • It is advisable to work with glass on wood surfaces.

Once again on how to drill a hole in glass

How to drill a hole in glass in 10-15 moments. To do this, you will need to sharpen a thin file like a chisel and attach it to a hand drill chuck. Do not forget to let the file cool down only at the moment of drilling, even occasionally sharpening it.

How to drill a hole in glass at home

When you need to drill a hole in glass, most people will most likely immediately turn to the services of specialists who will do this work for you and will require a certain fee. In truth, this process is not as difficult as it seems at first glance. Below we will talk about how to drill a hole in glass and what tools to use for this.

Proper preparation is the key to success

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

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

There are drills for holes of various diameters.

Cutting round glasses

We offer the possibility of cutting rounded glasses. A roller from the glass cutter is attached to one jaw of the caliper. Another sponge rests on the glass through a rubber washer. The roller is rolled a couple of times in a circle, then 3-4 tangents are drawn with a standard glass cutter, which facilitate chipping of the glass along the boundaries of the cuts. Sharpened edges are cleaned with a file or emery under running water.

How to cut round glass

For example, in the evening, young football players knocked out the glass for you with a ball. You fill the gap with glass from some interior room, but it is slightly larger in size. What to do? Glass cutters are clearly no longer working, running around neighbors in search is not a fact that you will find. So that we have to remember the folk methods of dealing with fragile material.

How to cut glass without a glass cutter? Several methods have been invented to solve this problem. Each of them gives quite high quality results. We hope that our tips will come in handy if the necessary tool is missing or lost among other things.

Water and scissors

The method is not universal and is suitable only for thin glasses with a thickness of no more than 3 mm. But almost the simplest. In addition, it allows you to cut not only in a straight line, but also figuratively, if you need glass of a certain shape (for example, an insert in a door). Another drawback. you won’t be able to cut too large a piece.

First of all, take a shard of the same glass and try to trim on it. If the glass cracks during operation, it means that it is tempered, and this method is not suitable in this case. If everything is in order, then let’s proceed.

The desired contour is marked on the glass with a marker. Or a fishing line is drawn if you just need to cut off the excess. Some craftsmen advise cutting out the template from cardboard and sticking it on glass. In our opinion, this is not a good idea. Firstly, the paper will get soaked, and its rags will interfere with work. Secondly, there may be problems with the glue: the water-soluble one will not hold the template, and the waterproof one will then have to be removed from the surface with something. unnecessary trouble.

Water is poured into a wide basin. The edge of the glass to be cut is lowered into it. The deeper the piece is immersed, the easier the process will go. the water pressure helps it.

Strong scissors like tailors are taken, plunged under the surface, and pruning begins. The sensation is more difficult than when cutting paper or fabric. Rather, they resemble working with cardboard. At the same time, crumbs are also formed, so it is better to cut with protective glasses in case of a rebound, if you did not immerse the glass deep enough in water.

Gloves also do not hurt, and they will, perhaps, be even more useful than glasses, since you will not notice the fragments in the water, but they cut hard.

Thermal method

In cases where the glass is thick or so large that it does not fit in the basin, it is suggested to find it in a soldering iron. Some have used a woodburner for similar purposes. And those who are especially poor for a tool. even a red-hot nail. Although it will take a very long time to bother with cutting glass, since you need to constantly heat it up.

  • Glass is laid on a flat surface.
  • The cutting line is outlined. Here, by the way, curly cut is also available.
  • At the very beginning of the line, a neat, not too deep file is made on the edge of the glass with a file or file. You can tear off the edge of the angle grinder (only extremely, carefully, at the lowest speeds!) Or even scratch it with a nail.
  • The soldering iron turns on. When heated, inserted into the incision.
  • The soldering iron is slowly, without much pressure, is drawn along the drawn contour. If the line is straight, and you are not sure that you can draw it straight at such a low speed, attach a metal ruler and move the soldering iron along it.
  • A thin crack appears behind the tool along the traced mowing line. To separate two pieces of glass, a thick mitten is put on (a kitchen oven mitt is suitable at home) and the unnecessary cut is neatly broken off. If you have a curly cut, it is better to lead the soldering iron as slowly as possible so that a fraction of a millimeter remains to break off, and the openwork is not damaged when separating the pieces.

Cutting Glass Circles

Thermal method No. 2

When using it, it is especially important to comply with all fire safety measures, since it involves the use of open fire.

  • The glass is again placed on a flat surface. This time, care should be taken that it is not flammable.
  • Cutting line is drawn on the glass.
  • From a thin cord with a diameter of 1-2 mm. a piece is cut to the width of the glass. Only twine made from natural materials is suitable. cotton, linen, synthetics are not suitable.
  • The rope is impregnated with something combustible. kerosene, campfire, gasoline, lighter refill. and laid straight along the mowing line.
  • The cord is ignited so that it ignites along its entire length.
  • When the fire is almost extinguished, the cut line is spilled with cold water. Glass cracks exactly at the place of burning.
  • If the crack has not reached the end, you can go in two ways: wipe the surface and repeat the trick with twine, or put the glass on the edge and lightly tap on the mowing line with a wooden or rubber pad.

Sometimes even craftsmen use this method to create original vases, candlesticks, glasses and ashtrays from empty bottles and glass jars. A glass cutter for creating such masterpieces is of little use, since it is very inconvenient for them to saw a curved surface.

Glass containers in the right place are tied with a combustible cord, especially since the temperature difference is created in the case of a bottle is very simple: it is immersed in a bucket of water.

Often, roughness and small fragments remain at the glass cutting site. To eliminate them, a fine sandpaper is taken, and the incision is sanded until smooth. This stage is especially important if you have built an elegant glass from a beautiful bottle: without such treatment, there is a great risk of injuring your lips or swallowing a piece of glass that is invisible to the eye.

So it is quite possible to do without special tools, using one of the folk notions of how to cut glass without a glass cutter.

How to cut round glass?

Now let’s look at the easiest way to cut round glass. To do this, you need to take a glass cutter and tools in order to cut an even circle. First, mark the center of the circle on the glass, then attach the suction cup to the place where the center was marked. We will tie a rope to the installed suction cup, and a glass cutter should be tied to the rope. The length of the rope from the suction cup to the cutter should be equal to the radius of the circle that you plan to cut. After all the preparations are completed, you can draw a circle on the glass with a glass cutter. Now draw “rays” from the resulting circle on the rest of the glass with a glass cutter. And after that, with ticks, break off the extra pieces that are between the previously held “rays”.

Cutting glass with a diamond saw

If it becomes necessary to cut round glass, but there is no glass cutter or tubular glass, then you can use a diamond saw. A diamond saw is a smooth diamond-coated strip where the teeth of a regular saw are.

In order to work with a diamond saw, it is necessary to cut a stencil of the circle to be cut out of thick cardboard or plywood. After that, the cut out stencil must be glued to the glass. When these preparatory work is done, you can start sawing with a diamond saw. During the sawing process, the glass from which the circle is cut must be constantly moistened with water, so the process of cutting the round glass must take place in the bathroom. If you decide to cut a circle out of glass using a diamond saw, then you need to be patient and cut the glass with great care.

How to cut round glass?

In our life, situations arise when a circle must be cut out of ordinary glass. If you take a glass cutter and a ruler and try to cut such glass, then you will not succeed, because such a task must be approached with all responsibility and seriousness. There are several ways to cut round glass. The choice of method depends on the thickness and dimensions of the glass.

To cut round glass, you need to prepare the necessary tools and items. These include:

Glass cutter;
Drill;
Protective glasses;
Ticks;
Diamond blade;
Abrasive;
Rope and suction cup;
Thick cardboard;
Scissors;
Tubular drill;
Capacity with water;
Scissors.

How to cut round glass less than 30 centimeters in diameter?

If it becomes necessary to cut a circle with a diameter of less than 30 centimeters, then for this you need to use a tubular drill. A tubular drill is a tube made of metal that has a fastener for fixing it in the drill chuck. The edges of the tubular drill must be smooth, because glass is cut with an abrasive and water. Before you start cutting a circle out of glass, you need to apply an abrasive with water to the edges of the circle, and when cutting a circle from glass, the abrasive with water should always be under the tubular drill so that the glass does not overheat and crack. If done correctly, the result will be an even circle.

Cutting thin glass

If you have thin glass available, you can cut a circle out of it with ordinary scissors. To do this, you need to make a stencil on the glass using a waterproof marker. After that, you need to place the glass in water, take scissors and cut out a circle using a stencil, biting off small pieces of excess glass with pliers, while gradually approaching the shape of a circle. With this method of cutting a circle from glass, the circle will turn out to be uneven, but if an urgent situation arises and a glass circle is needed, then you can use these methods of cutting a circle from glass. This method is used when only scissors can be found from the tools. If the glass is 2-3 mm thick, then a circle can be cut out of it with scissors. And if the glass is thicker, then you need to apply the methods described above.
