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 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 considered specialty
bits. To sharpen them, align them in the Chuck as you do standard
bits. Check the position of the two Flats on the Chuck and draw
an imaginary line from the middle of the flat up through the drill
bit (3/32" to 1/2").
If the alignment does not match the illustration shown, align
the drill bit so that the heel of the drill bit
is in alignment with the middle of the
chuck’s flat (see illustration), and
tighten the Chuck.
Follow the normal sharpening
procedure. You may have to
realign and sharpen more than
once to ensure that the bit is
sharpened correctly.
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 number of half-
turns when you sharpen.
• Make sure that there are no particles between the chuck jaws
and the drill bit which could hold it off center.
• Make sure the bit is not loose in the Chuck.
