Angle grinder (angle grinder) is a universal electric tool. Without it, it makes no sense to start construction or repair work. Quickly cut materials or process their surface - all these tasks lie in the range of angle grinders. The second common name for the instrument is "Bulgarian". Its versatility is achieved due to the presence of different types of circles, the arsenal of which allows you to work with metal, wood, brick, tile, stone, plastic, concrete, etc.
Technical features of angle grinders
Manufacturers produce a large number of angle grinders. For this reason, the performance indicators have a serious gradation. The angle grinder runs at high speeds. Its power can be from several hundred watts to more than 2 kW. When choosing a tool, attention is paid to the following parameters:
- maximum disk rotation speed;
- maximum disk diameter size;
- spindle thread;
- type of food;
- weight
For domestic purposes, mainly grinders with a power of 600–900 W or 1200–1500 W are used. For professional work - from 1800 to 2100 watts. The number of revolutions depends on the power of the tool, so the operating range can be from 1000 to 12000 rpm. Household and professional angle grinders are distinguished by their ability to work for a long time without overheating.
Relative to tool weight. The higher the specifications, the heavier the tool. In this case angle grinder able to work with the hardest materials, giving a high efficiency.
Features of use and materials
The main criteria for choosing a grinder are the power and diameter of the circle. It depends on them what material you can work with:
- Circle 115 mm. Appointment — fast cutting of products from metal and alloys. Diamond blades are segmented and cast. You can work with concrete, stone, marble slab, granite, brick, porcelain stoneware, paving stones.
- Circle 125 mm. Purpose - cleaning and polishing surfaces. Depending on the type of disc (cutting or abrasive), it works with tiles, paving stones, metal. Grinding and polishing of surfaces can be of this type: stainless steel, chipboard, fiberboard, parquet, paintwork.
- Circle 150 mm. Appointment — cutting of preparations of average thickness from metal, stainless steel. Suitable for hardened, tool and high speed steels.
- Circle 180 mm. It is used for cutting pipes with a diameter of more than 21 mm, as well as for sheets of metal, stone, concrete.
- Round 230 mm. Purpose - work with reinforced concrete blocks, thick cast iron, bricks.
An angle grinder is a convenient and necessary tool in everyday life, in construction, in repair and furniture fields of activity. If you have a wide range of cutting, grinding wheels and their correct choice according to purpose and parameters, the quality, speed and result of work will be on top.
