Identifying Correctly Sharpened Drill Bits

(and what to do with those that aren't!)
Correctly Sharpened Bits
Chisel Point
Heel
Cutting Edge
Problem
The Chisel Edge
is ground flat.
Problem
Surface of the
bit isn't smooth
and/or heavy
grinding sound.
10
The entire surface 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 (positive relief).
Cause
Alignment Fingers did not
position the drill bit properly
in the aligning process (page
7-8).
Solution
Realign the bit by carefully fol-
lowing steps 1 through 3 on
page 7-8.
Cause
Too much drill bit is sticking out of
the end of the chuck.
Solution
Realign the bit. During the re-align-
ment process, be sure to keep the
White Triangle against the Cam
Guide as you insert the Chuck into
the Sharpening Port to set the depth
of the bit. The bit should be pushed
up inside the Chuck and should
rotate slightly as the Chuck is
plunged into the Sharpening Port
and contacts the Diamond Sharpen-
ing Wheel. Push until the Chuck is
fully inserted into the Port.
