Step 1: Preparation

Put on protective glasses or goggles. The grinding wheel should be of fine grit and should be flat.

Step 2: The point angle

The bit should be held at a 60 degree angle to the grinder. Grind until this edge is created.

Step 3: Lip clearance

To create the lip clearance, move the bottom end of the bit towards the grinder to increase the angle. At the same time, rotate the bit clockwise a quarter of a turn.

Step 4: Check

The cutting angle, cutting edges and the angle of the lip clearance should be the same on both sides of the bit.
