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.
