Heavy-Duty Carbide Tipped Tool Bit
Read these instructions over carefully, and look at the Tool Bit
before it is used to become familiar with its shape.
1. Use a green Silicone Carbide Grinding Wheel about 54 Grit, H
Grade.
2. The angle of the Carbide (7°) and the Holder Body (10°) and the
Rake (15°) are indicated in the illustration. These angles must be
maintained when grinding.
3. The Radius at the tip of the Carbide is important. Hold it as close as
possible to 1/32 of an inch.
4. Grind the Shank first. Dress the Grinding Wheel to clean all metal
out of it, then grind the Carbide.
5. Remove stock a little at a time. Do not allow the Tool Bit to heat up.
6. Dress the Radius on the Carbide Tip with an AMMCO No. 905764
