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:
• Chuck not pushed all the way into the Sharpening Port.
• Drill not aligned correctly.
• Chuck is dirty and the bit slipped out of alignment. See
"Cleaning the Chuck, " to correct.
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. Making sure it is sticking
out 1/2", 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. Sharpen
until there is no more grinding noise.
• 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 considered spe-
cialty bits. Your Drill Doctor does not sharpen these types of
bits.
