How to choose the right glass cutter

To know how to choose a glass cutter, you need to familiarize yourself with the design and purpose of existing tools for sale. Each type of tool is used depending on the thickness of the glass and its capabilities. The choice of a diamond glass cutter guarantees the universality of its application. This is the most common type of glass cutter.

Glass Cutter Types

Varieties of glass cutters.

The diamond used in the construction of this glass cutter is not a precious, but roughly treated stone, attached to a mandrel using silver solder. The frame of the mandrel is also a miniature hammer.

Kinds of glass cutters by the principle of their action

The process of cutting glass depends on the skill of the artist. Diamond option allows you to speed up this skill. The trace of the interaction of diamond with glass is barely noticeable from its subtlety. You can cut them more carefully compared to other types of glass cutters. After the diamond tool there is practically no need to additionally process the cut edge. When choosing, it is useful to hold the glass cutter in your hand, feeling the level of convenience and comfort during use. The main advantage of a diamond glass cutter is its large potential resource. Diamond is the hardest material in the world. They can make an edge longer than 10 km. The choice of diamond tools will allow the newcomer to get used to faster.

In addition to natural diamond in the designs of glass cutters used artificial. The choice of an artificial variant will be cheaper, but in application it is almost as good as natural ones. Depending on the design of the working faces, there are two types of diamond tools: with a curvilinear cutting edge and with an edge in the form of a quadrangular pyramid. The curved head is used for glass with a thickness of no more than 4 mm. The edge in the form of a pyramid allows you to cut glass with a thickness of up to 7 mm with natural diamond and up to 5 mm with synthetic. After dulling, the quadrangular pyramid is turned 90º and continues to work. For such a rotation, it suffices to loosen the locking screw. For a novice master, it is better to use a glass-cutter with a curved edge, since the cutting part in the form of a quadrangular pyramid is inclined from the glass-cutter axis at an angle of 20º.

In a roller tool, the cutting element is a wheel rotating on a fixed axis fixed in the mandrel. When choosing a tool, you should pay attention to the gap between the axis and the roller. If the roller hangs, it greatly affects the quality of the cut edge. The roller is made of hard tungsten alloy with cobalt. This allows an incision of up to 300 m of edge. If the roller is blunt or worn the axis, then it is changed to another, consisting of a glass cutter. To do this, loosen the screw on the drum holding the rollers and turn it to the angle that allows you to use the next roller.

Cutting glass with a glass cutter.

Best of all, cutting is done using an oily liquid. Mineral oil and kerosene are used as such liquid. Kerosene has the property of good penetration into any gap at almost a molecular level. This allows you to make a well-controlled rift. Rollers come in different angles. For thicker glass use a roller with a large sharpening angle. A roller with a sharpening angle of 138º is used for glass thicknesses up to 8 mm. For cutting glass up to 20 mm thick, the grinding angle should be 160º.

Liquid for cutting refuels in the special tank which is built in the handle of the glass-cutter. The lubricant is fed to the roller by means of a wick. Resource roller with the use of lubrication - up to 5 km of cut. The choice of lubricant is of great importance.

Glass cutter oil must meet certain requirements.

It must penetrate well into the cut part of the glass, at the same time have good adhesion in order to stay on the roller and not spread over the glass. It is best to use a special oil for cutting glass. It is expensive, but small packaging will last for a long time. The choice of tool, of course, is better to stop on the lubricated version.

On all types of tools, there are grooves on the hammer-shaped part, which are used to break off small pieces of glass left with poor-quality cutting. If you want to cut a circle from a glass or an oval, then use devices like a compass, or a special lever system of two perpendicular guides with suction cups for glass and directly glass cutter.

The head of the glass cutter can be fixed and rotating relative to the axis of the handle. The rotating head is used to cut smoothly curving lines in a pattern.

If you choose a quality tool, then it will be expensive, but it is suitable for all occasions. If the work on cutting glass is to be disposable, then you can get by with a cheaper, but lower-quality design option.
