Q:Why hand grinding sand turbine, electric drill, impact drill and other power tools plug is two, plug is not three plug

Each of these devices has a "back" logo indicating double insulation protection, and the double insulated layer forms insulation protection between the outer shell and the inner part of the tool, thereby preventing the occurrence of electric shock. So no three plug in,

Q:What material does the power tool housing fit?

Electric drill: the main specifications are 4, 6, 8, 10, 13, 16, 19, 23, 32, 38, 49mm and so on. The figures refer to the steel whose tensile strength is 390N/mmThe maximum diameter of a drill drilled on a material. For non-ferrous metals, plastics and other materials, the maximum drilling diameter is comparable to the original specifications of 30 to 50%.Electric grinding machine: a tool for grinding with a grinding wheel or millstone. A vertical electric wheel and electric angle grinder.Electric wrench and electric screwdriver: used for loading and unloading threaded fittings. The driving mechanism of the electric wrench is composed of a planetary gear and a ball screw groove impact mechanism. Specifications are M8, M12, M16, M20, M24, M30 and so on. An electric screwdriver adopts a clutch, a transmission mechanism, or a gear drive mechanismThere are M1, M2, M3, M4, M6 and so on.

Q:What's the name of an electric tool for riveting screws into wood? Not understand!
