The main specifications include 4, 6, 8, 10, 13, 16, 19, 23, 25, 32, 38, 49mm, etc. The numbers refer to the maximum diameter of the drill bit drilled on steel with a tensile strength of 390N/mm. The maximum drilling diameter for materials such as non-ferrous metals and plastics can be 30-50% larger than the original specification, equipped with a polishing machine.
Electric wrenches and screwdrivers
Used for loading and unloading threaded connections. The transmission mechanism of an electric wrench consists of a planetary gear and a ball spiral groove impact mechanism. The specifications include M8, M12, M16, M20, M24, M30, etc. The electric screwdriver adopts a tooth embedded clutch transmission mechanism or a gear transmission mechanism, with specifications such as M1, M2, M3, M4, M6, etc.
Electric Hammer and Impact Drill
Used for drilling, grooving, and roughening concrete, brick walls, and building components. By using expansion bolts, the installation speed and quality of various pipelines and machine tools can be improved; The impact principle of an electric hammer is to generate impact power through internal piston movement, while the impact principle of an impact drill is to generate impact power through gear running in, so the impact force of the electric hammer is greater.
Used to compact concrete when pouring concrete foundations and reinforced concrete components to eliminate air holes and improve strength. The high-frequency disturbance force of the electric direct connected vibrator is formed by the motor driving the eccentric block to rotate, and the motor is powered by a 150Hz or 200Hz intermediate frequency power supply.
Used for planing wood or wooden structural components, mounted on a platform or used as a small planing machine. The cutter shaft of the electric planer is driven by an electric motor shaft through a belt.
Commonly known as a grinding machine; Electric grinding; Electric grinding machine, an electric tool used for grinding with a grinding wheel or disc.
