What is the principle of a lithium electric impact drill?

The principle of the lithium-electric impact drill is to generate impact force through the rotation of the motor, thereby achieving high-speed drilling or screw tightening.
Specifically, a lithium-electric impact drill contains a motor and an impact device. The motor provides the main power for drilling or tightening screws by driving the rotation of the drill bit or screwdriver head. At the same time, the motor also generates high-speed impact force during rotation.
The impact device is located between the motor and the drill or screwdriver head, and it converts the rotation of the motor into impact force through a series of gears and cam mechanisms. When the motor rotates, the impact device will move up and down in rapid pulses to generate impact force.
This impact force can help overcome the material's resistance during drilling, allowing the drill bit to penetrate solid structures faster. The impact force can provide additional torque for screw tightening, making tightening easier and more efficient.
In general, lithium-electric impact drills use the rotation of the motor to generate impact force and use this impact force to achieve high-speed drilling or screw-tightening functions, improving work efficiency and convenience.
