Questions and Answers

1. Question:
Why was my drill bit sharpened improperly?
Answer:
The most common cause of improper sharpening is
improper drill bit alignment.
Key causes are:
1. Chuck not pushed all the way into the Sharpening
Port.
2. Drill not aligned in the Alignment Fingers correctly.
4. Chuck is dirty and the bit slipped out of alignment. See
page 17, "Cleaning the Chuck," to correct.
5. Too many rotations of a small-diameter bit results in
incorrect sharpening, and too few on a large bit may
not sharpen enough. See page 11–12, "Drill Bits of Dif-
ferent Sizes."
In order to correct these problems be sure the Chuck is all
the way in the Sharpening Port with the Guides correctly
matched up.
2. Question:
When I aligned the drill bit and sharpened it, why was
no material removed?
Answer:
This happens when the bit is not protruding out of the
Chuck far enough. The Chuck may not have been tightened
enough and the bit may have slipped in the Chuck.
Carefully realign the bit in the Chuck and set its depth in
the Sharpening Port again.
3. Question:
I sharpened the bit. Why will it not cut?

Answer:
This happens when the Heel on the bit is higher than the
Cutting Edge (negative relief). Realign the drill bit and
resharpen in the Sharpening Port.
• Maintain consistent inward light pressure during the
half-turns of the Chuck.
• You may have a specialty drill bit. Slow and fast spiral,
helix, turbo flutes, and raised margin drill bits are con-
sidered specialty bits. Your Drill Doctor does not
sharpen these types of bits.
• Follow the normal sharpening procedure. You may
have to realign and sharpen more than once to ensure
that the bit is sharpened correctly. If the problem per-
sists contact the Technical Service Department.
4. Question:
Why is the drill point off center?
Answer:
If the tip of the drill bit appears to be sharpened off center,
check the following items:
• You may not have completed an even number of half-
turns when you sharpened and one face of the bit was
ground more than the other. Always use an even num-
ber of half-turns when you sharpen.
• Make sure the Chuck is clean.
• Make sure the bit is not loose in the Chuck.
• During the sharpening process be sure to keep the
same pressure on each half-turn.
5. Question:
What can I do about flat spots on the bit point between
the Cutting Edge and the Heel?
Answer:
The flat spots on a sharpened bit are the result of an incom-
plete or paused half-turn of the Chuck in the Sharpening
Port. To correct, apply light, inward pressure and rotate the
Chuck smoothly while sharpening. Be sure to complete the
half-turns.
