- Start Grinding: Activate your electric drill at a moderate speed. Gently push the drill bit into the grinding wheel. Apply light, consistent pressure.
- Check Sharpness: Periodically remove the drill bit to check its sharpness. Continue grinding until the desired edge is achieved. The cool design of the sharpener helps prevent overheating.
