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 drilled on the steel with tensile strength of 390n / mm. For nonferrous metals, plastics and other materials, the maximum drilling diameter can be 30-50% larger than the original specification, with a polishing machine.
Electric wrench and electric screwdriver
It is used for loading and unloading threaded connectors. The transmission mechanism of electric wrench is composed of planetary gear and ball spiral groove impact mechanism. Specifications include M8, M12, M16, M20, M24, M30, etc. The electric screw driver adopts tooth clutch transmission mechanism or gear transmission mechanism, and the specifications are M1, M2, m3, M4, M6, etc.
Electric hammer and impact drill
Used for drilling, slotting and roughening on concrete, brick wall and building components. Combined with the use of expansion bolts, the installation speed and quality of various pipelines and machine tools can be improved; the impact principle of electric hammer is that the impact force is generated by the internal piston movement, and the impact principle of impact drill is that the impact force is generated by gear running in, so the impact force of electric hammer is greater.
Concrete vibrator
It is used for tamping concrete when pouring concrete foundation and reinforced concrete components to eliminate air holes and improve strength. The high frequency disturbing force of the electric direct connected vibrator is formed by the motor driving the eccentric block to rotate, and the motor is powered by 150Hz or 200Hz medium frequency power supply.
Eletirc planer
It can be used for planing wood or wood structural parts. It can also be used for small planing. The cutter shaft of the electric planer is driven by a motor shaft through a belt.
Electric grinder
Commonly known as grinding machine, electric grinding machine, electric grinder, electric tool for grinding with grinding wheel or grinding plate.
