According to the "Report on the Forecast and Transformation and Upgrading of Production and Sales Demand in China's Electric Tool Industry", electric tools are mainly divided into metal cutting electric tools, grinding electric tools, assembly electric tools and railway electric tools. Common electric tools include electric drills, electric grinders, electric wrenches and screwdrivers, hammers and impact drills, concrete vibrators, and electric planers.

Electric drill

The main specifications are 4, 6, 8, 10, 13, 16, 19, 23, 25, 32, 38, 49mm, etc. The number refers to the maximum diameter of the drill bit for drilling on steel with a tensile strength of 390N/mm. The maximum drilling diameter for non-ferrous metals, plastics, and other materials can be 30-50% larger than the original specification, with a grinder.

Electric wrenches and screwdrivers

Used for loading and unloading threaded connections. The transmission mechanism of the electric wrench consists of a planetary gear and a ball spiral groove impact mechanism. Specifications include M8, M12, M16, M20, M24, M30, etc. Electric screwdrivers use jaw clutch transmission mechanisms or gear transmission mechanisms, with specifications including M1, M2, M3, M4, M6, etc.

electric hammer and impact drill

Used for drilling, grooving, and roughening concrete, brick walls, and building components. When used in conjunction with expansion bolts, it can improve the installation speed and quality of various pipelines and machine tool equipment. The impact principle of the electric hammer is to generate impact power through internal piston motion, while the impact principle of the impact drill is to generate impact power through gear running-in. Therefore, the impact force of the electric hammer is greater.

Concrete vibrator

Used for tamping concrete during the pouring of concrete foundations and reinforced concrete components to eliminate air pockets and improve strength. The high-frequency disturbance force of the electric direct-coupled vibrator is generated by the rotation of an eccentric block driven by an electric motor powered by a 150Hz or 200Hz medium-frequency power supply.

Electric planer

Used for planing wood or wood structural components, it can also be used as a small bench planer when mounted on a stand. The blade shaft of the electric planer is driven by a motor shaft through a belt.

Electric grinding

Commonly known as grinder; electric grinder; electric grinding machine, an electric tool that uses a grinding wheel or disc for sanding.
