The sharpening process includes 3 easy procedures:
1. Align the bit in the Chuck.
2. Sharpen the bit.
3. Split the point (if you choose).
Be sure to complete all three of the procedures to sharpen
and split a bit and always sharpen the bit prior to splitting it.

It is important to understand that

each bit has all of these charac-
teristics.
When viewing a well-sharpened
bit from the end, the entire sur-
face from the Cutting Edge to the
Heel will have a finely ground
surface without ridges or indenta-
tions. The Heel will always be
lower than the Cutting Edge.
