Questions and Answers

1. Question:
Why was my drill bit sharpened improperly?
Answer:
The most common cause of improper sharpening is drill
bit alignment.
Key causes are:
1. Chuck not pushed all the way into the Alignment Port.
2. Drill not aligned in the Chuck Jaws correctly.
3. The type of drill requires an angle adjustment to
achieve the desired Chisel and Relief Angles. Try using
the Variable Alignment to adjust the Chisel and Relief
Angle (see page 18).
4. Chuck is dirty or the bit slipped out of alignment. See
pg 24, "Cleaning the Chuck."
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 16, "Drill Bits of
Different Sizes."
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. You may have allowed the Alignment
Button to knock the bit back into the Chuck when aligning
the bit. Carefully realign the bit in the Alignment Port
again. Make sure the drill bit is pushed all the way against
the Drill Stop before you release the Alignment Button.
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). To correct this problem,

follow the instructions in "Using the Variable Alignment to
Adjust the Chisel and Relief Angle" on page 18–19.
You may have a specialty drill bit. Slow and Fast Spiral,
Helix, Turbo Flutes, and Raised Margin drill bits are con-
sidered specialty bits. If you're are getting insufficient
relief on specialty bit types, try aligning all the way in the
(+) setting on the alignment port. This will help improve
the sharpening on these types of bits.
4. 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
incomplete or paused half-turn of the Chuck in the Sharp-
ening Port. To correct, apply light, inward pressure and
rotate the Chuck smoothly while sharpening. Be sure to
complete the half-turns.
5. 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 done 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 that there are no particles between the
Chuck Jaws and the drill bit that could hold it off cen-
ter. Check the drill bit to ensure it is straight and free
of burrs.
• 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.
