An angle grinder is a hand-held power tool with an abrasive disk that spins at an impressive rate. The owner can use the unit to perform the grinding, cutting, and even sanding. It can be exploited in any fields of activity, but most often this tool is used: - by plumbers – the professional cuts pipes with it; - in house building and restoration projects – also pipes cutting, as well as channels, pavers, ceramic materials, etc. The grinder works by rotating the spindle, on top of which a specific nozzle is installed, such as a special brush or disk (grinding or cutting).
