Exhibition introduction: Wireless drills are mainly powered by batteries, which are converted into mechanical energy through electric motors to drive the drill bit to rotate and achieve drilling functions. Trigger the switch to control the motor voltage. The deeper the press, the higher the voltage and the faster the motor output speed; The forward and reverse switches can change the polarity of the motor circuit to achieve forward and reverse rotation of the drill bit. Used in home decoration, construction, and some industrial production fields, wireless drills can be used for parts processing, assembly, and maintenance work, such as automotive manufacturing, mechanical processing, and other industries.
