Lithium brushless electric Angle grinder is in using high speed rotating thin grinding wheel and rubber wheel, wire wheel, grinding and cutting of the metal artifacts, rust removing, polishing processing. Angle grinder brush suitable for cutting, grinding and grinding metal and stone, water cannot be used when homework. When cutting stone material must be used to guide plate. In view of the aircraft is equipped with electronic control device, if in such suitable installed on machine accessories, can also for grinding and polishing operation. Lithium electricity in power tools and current brushless is a trend, but in the past in this respect everybody is only a change of voltage, it can't say innovation, through a large number of market after verification, get wei draw a conclusion that is how electric tools should meet for a long time, high strength, no under extreme conditions, such as power supply applications.
