Cause
The bit isn’t completely ground yet.
Solution
Continue sharpening the bit until the
chisel is clean and straight. If the
machine quits removing material be-
fore the chisel is clean, re-align and
sharpen again.
The entire surface from the Cutting
Edge to the Heel will have a finely
ground surface without ridges or in-
dentations. The Heel will always be
lower than the Cutting Edge (positive
relief).
Cause
Drill bit alignment.
Solution
Re-align the drill using the Adjustable
Alignment procedure on page 55. To
increase relief, insert the Alignment
Guide on the Chuck closer to the
(+) side of the Alignment Port, then
sharpen the bit.
Cause
Chuck is too loose or you are using too
much pressure when sharpening.
Solution
Use more torque when tightening the
Chuck or less pressure when sharpen-
ing. Clean the Chuck with compressed
air if the problem persists.
