How to cut round glass at home

How to cut with the glass cutter

The easiest way to get a circle out of glass is to cut a shape with a glass cutter. Initially mark out the center part of the glass circle using a plastic suction cup. Next, a thread, the length of which should be equal to the radius of the required circle, is tied to this mechanism. Tie the glass cutter to the end of the rope. After that, the rope is stretched and the glass cutter draws the fishing line around the suction cup. After drawing the circle, you need to make more radial mowing lines coming from the outer part of the circle.

Important! Beveling lines are needed to gently break off any excess glass that interferes with the cutting of the circle.

How to cut a round glass for a watch

Situations arise in our lives when it is necessary to cut a circle out of ordinary glass. If you take the glass cutter and ruler and try to cut this kind of glass, you will not succeed, because this task must be approached with great responsibility and seriousness. There are several ways to cut round glass. The choice of method depends on the thickness and size of the glass.

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

Glass cutter; Drill; Safety glasses; Pliers; Diamond blade; Abrasive; Rope and suction cup; Tight cardboard; Scissors; Tubular drill; Container with water; Scissors.

How to cut a round glass

Life can sometimes baffle you with a completely unexpected problem. For example, how to cut glass without a cutter, if you suddenly do not have one handy, and it is necessary to work urgently? Not everyone has it on the list of necessary tools. I don’t want to buy it for a one-time job. once in a lifetime to cut a new mirror, and then the tool will lie idle for years without use.

For example, in the evening young soccer players hit you with a ball. You fill the gap with glass from some indoor room, but it is slightly larger in size. What to do? Glass cutters obviously do not work anymore, running around the neighbors in search. not the fact that you will find. So we have to remember folk methods of dealing with the fragile material.

How to cut glass without a glass cutter? There are several ways to solve this problem. Each of them gives quite good results. We hope that our tips will be useful if the necessary tool is missing or lost among other things.

The method is not universal and is suitable only for thin glass, with a thickness of no more than 3 mm. But it’s almost the easiest. In addition it allows you to cut not only in a straight line, but also in a curved form if you need a specific shape of glass (for example, an insert in a door). One more disadvantage. you can’t cut too big a piece.

How to Cut Glass Bottles Perfectly at Home

First of all, take a piece of the same glass and try to cut on it. If the glass cracks while working, it means it is tempered and this method is not suitable in this case. If it’s okay, then let’s go.

On the glass marker outlines the desired contour. Or use fishing line if you just want to cut off the excess. Some craftsmen advise cutting out a template from cardboard and gluing it to the glass. In our opinion, not a good idea. First, the paper gets soaked, and its rags will interfere with the work. Secondly, there can be problems with glue: water-soluble will not hold the template, and water-resistant will then have to take something off the surface. an extra hassle.

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

We take strong scissors like tailor’s scissors, dip them under the surface, and start cutting. It is more difficult to cut than paper or cloth. Rather reminiscent of working with cardboard. It also produces crumbs, so it is better to cut in safety glasses in case of rebound if you do not sink deep enough in the water.

Gloves also do not hurt, and will be, perhaps, even more useful than the glasses, as splinters in the water did not notice, but they cut badly.

Many do not believe that the scissors can cut glass, and are very surprised after they have tried it, that it is really possible.

In cases where the glass is thick, or so large that it does not fit in the basin, it is suggested to find a soldering iron. Some people used a wood burner for the same purpose. And especially poor on tools. even a red-hot nail. Although you have to take a long time to cut the glass with it, because you have to heat it up all the time.

  • The glass is placed on a flat surface.
  • A cut line is marked. Here, by the way, a shaped cut is also available.
  • At the very beginning of the line, a neat not too deep notch or file is made on the edge of the glass. It is possible to tear edge with angle grinder (but very carefully, on the lowest revolutions)!) Or even scratched it with a nail.
  • The soldering iron is switched on. When heated, it slides into the notch.
  • The soldering iron is drawn slowly, without much pressure. If the line is straight and you are not sure if you can hold it straight at such low speed, put a metal ruler and move soldering iron along it.
  • Behind the tool appears a thin crack along the outlined mowing line. To separate two pieces of glass, a thick glove (a kitchen oven mitt will do at home) is put on and the unwanted scrap is gently broken off. If you have a shaped cut, it is better to lead the soldering iron as slowly as possible, so that a fraction of a millimeter remains to be broken, and the tracery is not damaged when separating the pieces.

When using it, it is especially important to observe all fire safety measures, because it involves the use of open flame.

  • The glass is again placed on a flat surface. This time, make sure that it is not easily flammable.
  • A cutting line is drawn on the glass.
  • From a thin cord with a diameter of 1-2 mm. A piece the width of the glass is cut. Only natural materials like cotton or linen are suitable, synthetics are not suitable.
  • Soak the cord in something flammable. kerosene, campfire lighter fluid, gasoline, lighter fluid. and lay it flat along the mowing line.
  • The cord is lit so that it catches fire along its entire length.
  • When the fire is almost out, the cutting line is drenched with cold water. Glass cracked exactly at the point of burning.
  • If the crack has not reached the end, there are two ways to go: to wipe the surface and repeat Focus with a string or to put the glass on the edge and lightly knock on the mowing line with a wooden or rubber mallet.

Sometimes even masters use this method to create original vases, candlesticks, glasses and ashtrays from empty bottles and glass jars. Glass cutter for creation of such masterpieces is of little use, as it is very inconvenient to saw the curved surface.

Glassware in the right place is tied with a flammable cord, the more so that the temperature difference is created in the case of a bottle is very simple: it is immersed in a bucket of water.

Roughness and small splinters often remain in the place where the glass is cut. To eliminate them, take a fine sandpaper, and the cut is sanded to smoothness. This step is especially important if you have constructed an elegant glass from a beautiful bottle: without such treatment, there is a great risk of hurting your lips or swallowing an invisible to the eye glass fragment.

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

Glass is an interesting building material that has found its application in many areas of the modern world. In fact, it consists of quartz sand, dolomite and limestone, to which are added various components and impurities to obtain interesting properties. Note that it is the nature of these additives and the result at the end that contribute to the variety of pricing policy with respect to this material.

In order to use glass in construction, it goes without saying that it has to be created according to certain technologies. Most often glass is produced by the float method, in the application of which the glass comes out in the form of a sheet from the furnace, after which it is fired. However, despite this special method of production, construction glass comes in several varieties, which also have a separate production technology. Therefore, separately note that the construction glass is: sheet. used for finishing doors, windows and partitions, laminated. double glass construction, attached to each other by a polymer tape, tempered. the most durable type of construction glass, which is now actively used to design store windows, doors and corridor openings, reinforced. rather interesting glass products, consisting of several glass layers, between which there is a layer of polymer film; эne.

How to cut round glass?

Given the peculiarities of the glass materials mentioned above, it should be noted that cutting glass is a particularly difficult process, requiring attention, accuracy and, of course, professional tools. Nevertheless, if the question “How to cut round glass??”, especially at home, your attention is offered three possible variations of its solution, which with ease can be performed and independently. So, types of cutting round glass:

Template cutting is a fairly complex process that requires some knowledge in the field. For its implementation will need to be equipped with a glass cutter and a template for the glass. As a starting material for the template can serve any handy material (cardboard or plywood). Diameter of the template, as a rule, should be slightly smaller than that of glass with the mandatory reference to the thickness of the working tool. The main nuance of this process is the need for forceful pressure on the material, so as not to disrupt the production process;

Cutting with a caliper and a roller glass cutter. This is especially useful if you need to cut a lot of glass. True, in order to carry it out, it is necessary to modify the glass cutter itself somewhat for a comfortable cutting of the material, according to the previously conditioned round shape. On the handle of this tool, it is necessary to make a small hole for free entry into the sponge, and then the resulting structure is fixed with a wire. Under the base of the second sponge a piece of rubber should be placed, which in the course of the work will contribute to a more reliable way of cutting. Using pressure, the first cut is made, after which you will be able to make other circular cuts.

Cutting glass with a glass cutter

In essence, the process of cutting glass is quite unusual, but it may seem complicated only when you first try. If you perform the necessary actions in the right order, and cut with a certain speed and force, everything will work out for sure. The following guide, step by step, tells you how to properly cut with the glass cutter, but despite the completeness of the theory, we recommend that beginners first practice on less valuable shards. It is better to take up the basic material, at least after a couple of successful cuts.

The first thing to do is to prepare the glass for work. To do this, clean the surface of the glass from dust and dirt. The cutting line on a clean glass will be more uniform, increasing the chances of a clean cut. The washed surface should be wiped with newspaper and degreased with alcohol or kerosene. After all the procedures, leave the glass for 10 minutes to evaporate any remaining moisture.

It is better to mark the markings on the glass with a marker or a glassograph. To do this, simply measure out the size we need on both sides, put a ruler to the specified points and mark the line of the future cut.

The most responsible step of the entire process is to use the glass cutter on the glass. Take a roller or oil glass cutter (the diamond one is described in the video below) and spend a short fishing line, up to 5 mm from the upper edge. Next, from it lead the cutting roller to the end of our mark. Move the glass cutter across the glass in a precise, steady movement, with a pressure force just above the average. If the cutter is sharp and the applied force is optimal, you will hear a slight crackling sound. The resulting line should be even and translucent. Occasional dilation or breakage of the cutter line may be due to a blunted cutter or too much pressure. It is not advisable to go over the same area twice. It is better to take 5-10 mm distance from the initial mark and make a new cut.

The cutting culminates in the breaking of the glass. There are several correct ways to make a controlled chipping. It is always better to begin with the most delicate movement and, if this does not work, increase the tension (within reason).

Lay the glass on a table or other more or less flat surface so that the cutting line is parallel to the edge and extends a couple of centimeters beyond it. Next we take the glass cutter and lightly tap with the iron tip at one edge of the cutting line on the back side of the glass. When a small crack appears, simply break off the hanging piece of glass with a light movement of the hand.

If after a couple dozen shocks, the crack is not formed, go to plan B. We put a match, a nail or a toothpick under the edge of glass, along the mowing line of the cutter and we press a little on the cloth from the sides. If the glass is still intact after moderate pressure, you can resort to the roughest method. Align the cut line with the edge of a table or other surface and put pressure on the piece you want to break with your hand. Do it with gloves and safety glasses. Do not strain yourself too much. If the glass does not break then the cutting line is not deep enough and you would better try a new one and pay attention to the sharpness of your tool.

After you have successfully chipped the glass, you only need to secure it by scraping the edges with a fine-grained emery cloth or a burr. We hope that the above guide, will help you make an accurate cut of the glass. For more clarity, we recommend watching a video on how to use the glass cutter with a wheel and a diamond.

Tips on how to properly cut glass with a glass cutter

Glass is by nature an extremely fragile material that should be handled with extreme care. In order not to get additional losses during its cutting it is necessary to use the tools correctly and adhere to the proper working technique. First of all, you should familiarize yourself with the cutting device itself.

How to cut glass without a glass cutter

You can also cut glass without a glass cutter. Very often the simplest scissors are used for this procedure. To cut a fragile material with scissors, you need to put it in warm water and under it cut pieces of the size you need. Normal glass will cut just as easily with scissors as cardboard or other durable paper.

If a large piece of glass needs to be cut, it can be placed in a large basin or tub. Then go over the glass with the sharp part of the scissors, break off unnecessary parts of the glass. To avoid cutting yourself on a sharp edge, you must wear gloves beforehand. At the same time it is advisable to protect your eyes as well.

No more than 3 mm glass can be cut in this way. Figures can only be cut out with straight contours. In advance you must necessarily prepare a template and glue it to the glass, using glue. It is worth noting an interesting point: the more water will be over the glass, the easier it will be to cut the future product.

You can also use twine, some hot liquid and a small vessel which needs to be filled with cold water. On the glass you need to make the necessary marks, then impregnate the twine with alcohol or gasoline, fold it on the marks and set it on fire. As soon as you put out the fire, pour a thin stream of water on the fishing line. At this point, the glass should definitely crack. Then break off the glass along the crack that you get, and sand all the edges with sandpaper. If the crack did not appear, you need to repeat the whole procedure again. Very complicated shapes can be cut with this method, it all depends on how you arrange the string.

Types of cutting tools

You need a special tool to cut the glass sheets. the glass cutter. Now available in several versions: roller, diamond and oil.


Most often masters use roller glass cutters. These are devices that have a handle and a rotary disc, where there are up to 6 working elements in the form of a wheel. Sometimes the cutting element can become blunt, but this can be easily corrected. Simply turn the disc and engage the next jog wheel.

One roller can cut up to 350 meters of material. It can easily handle glass up to 4 mm thick. Hold the cutter vertically and apply slight pressure to the glass pane as you work. When you run the glass cutter along the entire length of the workpiece, you will see a whitish line on it, which will serve as your reference point for chipping.

A tool designed for professionals. A diamond cube, which can be natural or synthetic, serves as the cutting element. Cube. usually pyramidal in shape. allows up to 10 kms long. After processing, the cut line is dark and thin.


Sometimes professionals use oiled glass cutters. They are devices that have the form of a reservoir in the handle, from which oil is supplied to the cutting element by means of a wick. Lubrication reduces friction and prolongs tool life. Glass up to 20 mm thick can be cut with this tool. Capable of making cuts up to 5 km long as provided by the manufacturer. The heads of oil glass cutters do not have a rigid fixation. during work they rotate, which allows them to be used for pattern cutting glass.

Always check that the cutter is in good condition before you start cutting. To do this, use it on a piece of glass that is not in good condition. If there is nothing wrong with the tool, the cutting line will be continuous and thin. But sometimes something resembling a white scratch or intermittent line appears on the surface. This can occur if the cutting edge is blunt or if you use the tool incorrectly.

You are advised to first practice on a small piece of glass so that you can learn how to hold, press and guide the cutter properly. No pressure should be exerted on the glass cutter when using it. The main thing is to “catch” the cut. And the roller cutter is treated a little differently. it should be pressed to the sheet surface a little. There should not be any squeaking noise as the cutter moves across the glass. The sound should be soft and rustling. The line, which is carried on the sheet, should end strictly on the marked place near the edge.

Option 4:

Cutting Glass Circles

steamimpactor, in its “Dieselpunk Vision” vorklog project of Steamimpactor, cuts out “rounds” with a special drill: The crown is clamped in the chuck of the drilling machine, the cutting line is immersed in water and at the lowest possible three hundred revolutions per minute, with equal pressure on the crown, the prepared glass is transformed into the required googly rounds. After three minutes of leisurely drilling, I got two neat discs of the right diameter and color. Edges of disks processed on the sheet of sandpaper with wetting, after that, got perfectly “firm” glasses of three-millimeter thickness! I must say, in the absence of a drilling machine, the successful use of drill bits of this diameter, in a hand-held power tool, is almost impossible. I would like to finish I would like to present a very original way of processing Plexiglas, even if not directly related to the glass, but the way is very good, without straining can be done even lenses: I saw it in Arin(a) in his work WatchMashine at the contest. Part 1


Now for the tubes, bottles, cans and the like:

First, about the marking, because it will depend on how smooth will be your rings and how long you will “tinker” with finishing of the planes. Wrap a wide strip of paper (with a flat edge) tightly around your workpiece, as shown in the photo and draw a line marker on the glass (along the edge of the paper): Now let’s start cutting. Tip: You need to wet the cutting area liberally with water. The options everyone chooses from dipping the workpiece in the water, to a thin trickle or periodic dipping. The better the wetting, the cleaner the seam and the fewer chipped edges.

Method 1:

Using a glass cutter and a gas torch we separate the bottom of the bottle in the master class Recycle! (alternative materials in goggle construction). We make a circular mark with the glass cutter. Accuracy is not so important, the main thing is to try to make the risk continuous I repeat, we do not need a perfectly even cut, our task, just separate the bottom from the bottle. For the next step we need a propane torch, the flame of which we will evenly heat the fishing line left by the glass cutter, smoothly rotating the bottle around the axis The operation must be carried out with gloves, and protect your eyes with goggles! If heating is correct the process is accompanied by a crackling sound, and stops when we hear a muffled click indicating that the bottle is split in two.

method 2:

Trou, for his project in the Time contest, cut the rings with a diamond-tipped cutting disc: But even having such a useful tool, I follow some simple rules: a). Abundant wetting during cutting. б). To avoid chipping on the back side of the workpiece, I cut the workpiece from both sides (of course if you can get to the place of cutting). And if you are lucky enough to have a tubular drill bit and a diamond drill bit, you can cut even “unconventional” shapes in glass:

method 3:
