To use the Drill Grinder, follow these simple steps: 1. Adjust the knife according to the drill bit size. 2. Sharpen the tip angle. 3. Sharpen the cutting edge.

The DRILL FIXTURE GROUP POSITIONING system allows for convenient and straightforward adjustment. Simply adjust the scale pointer based on the outside diameter of the grinding bit, then rotate and position it accordingly.
