Working principle

The working principle of the drill sharpeners is the precision grinding of the cutting edge of the drill bit. The drill bit is firmly fixed in place, and the high-speed rotating grinding wheel contacts the cutting edge of the drill bit. The grinding angle and pressure are carefully controlled to ensure a precise and uniform grinding process. This process can restore the cutting ability of the drill bit, extend its life and improve its performance.
