Selection Tips
The Bosch brand tool has proven itself on the positive side, but when choosing the right device model for work, you should take into account several nuances that will facilitate and speed up the buying process.
- The primary task is to determine the range of operation, including the designation of the direction of the equipment. This point is important because professional and household tools will differ in cost, weight, and other important criteria. The powerful equipment is designed for many hours of daily use. As for household models, they will need breaks in the process of work.
- The next criterion for selecting a suitable angle grinder is the diameter of the working disk. Today, the line of the German brand includes devices designed to work with discs with a diameter of 115 mm, 125 mm, 150 mm, 180 mm, 230 mm. Smaller consumables are recommended for home use in order to sand products, remove paint and varnish materials and rust. More productive grinders will work with larger discs. Such elements can powerfully cut metal, concrete, stone, tiles, etc.
Peculiarities
Today, a fairly wide range of repair and construction tasks is performed by a grinder. This is due to the functionality, performance and simplicity of the machine, which is why this tool is present in the arsenal of home craftsmen and professional builders. Bosch grinders have established themselves in the market as a reliable and high-quality tool, since the manufacturer regularly modernizes the product range, and also produces improved angle grinders. The main criteria for the quality of the tool of this company are the ergonomics of the body, power and comfort in operation, as evidenced by numerous reviews of the owners of grinders.
The most popular series of Bosch grinders is the GWS line, however, the range of devices also includes other modifications of the units. The trade brand offers the consumer electric, battery and pneumatic grinders. Today, battery-powered devices are especially popular, which stand out for their mobility, for which they have gained fame as a tool for small professional work and household use.
The Bosch angle grinder operates on a fairly simple principle based on the work of an internal motor, which transmits force to the main working part of the mechanism - the grinding wheel. Craftsmen work with Bosch grinders with tiles, concrete and bricks, as well as with metal alloys of various thicknesses. The device copes with the processing of joints on workpieces after welding, with the help of UMSh, the grinding of paints and varnishes is carried out, and rust is also removed.
The distinctive features of the tool in question are considered to be the additional functionality that the manufacturer has endowed its devices with. Among this list, it is worth highlighting:
- balancing the device and protecting it from vibration during operation, especially for powerful high-performance models;
- the presence of a rotary handle-bracket;
- a casing for a vacuum cleaner;
- the design of the machines, assuming the presence of the SDS quick-locking nut, thanks to which it is possible to quickly and without additional tools replace the working disk.
Today the Bosch brand offers customers two types of angle grinders:
- one-handed - designed for one-handed operation;
- two-handed - to use them you will need to work with both hands.
Operation and maintenance
The multifunctional cutting tool is quite in demand in the course of performing various construction and repair tasks, but it is also quite tram-hazardous. That is why the operation of angle grinders requires compliance with safety regulations.
Any tasks with the grinder should only be carried out with glasses and a protective cover. In addition, it is necessary to take into account the basic rules for operating the tool:
it is forbidden to touch the discs immediately after using them, since during the rotation they become very hot and can provoke a burn;
the device should be held as tightly as possible in the hands, preferably with both limbs;
the position of the operator's body on the floor must be stable, therefore, if you feel unwell or fatigue, you should refuse to work with the cutting tool;
when using electrical devices, fix the cord so that it does not interfere during manipulation, in addition, it is best to fix it away from the disc;
during cutting, the machine must be positioned so that the cutting line passes by the master, which will reduce the risk of injury situations if the blade is jammed;
you can not make too much effort and put pressure on the grinder during work;
it is important to ensure that the cutting is carried out smoothly as the grinder moves.
Also, the power cord and plug deserve special attention. Before starting work, you should make sure that there are no creases and other damage that can provoke a short circuit. In battery models, it is necessary to monitor the health of the power supply. Also, during the maintenance of the tool, you need to monitor the condition of the carbon brushes and the armature, and lubricate the gearbox.
