Problem
The Chisel Edge is not
clean or straight.
Problem
Insuffecient (negative)
relief or a slow cutting
drill bit.
Heel Cutting Edge
Problem
Bit is backing out or
slipping out of the jaws
when you are sharpening.
16
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 before the chisel is
clean, re-align and sharpen again.
The entire surface from the Cut-
ting Edge to the Heel will have a
finely ground surface without
ridges or indentations. 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 22. 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
sharpening. Clean the Chuck with
compressed air if the problem
persists.
