Sharpening Bits of Dierent Lengths, Diameters,
and Types
Dierent size drill bits may require a dierent number of rotations.
Continue to sharpen until you no longer hear grinding noise. This
will result in a Chisel Edge that is clean and straight and the entire
surface from the Cutting Edge to Heel is nely ground.
Large Drill Bits
The Model XP sharpens bits from 3/32” to 1/2”. You can also
purchase the optional Large Bit Chuck that sharpens bits up to
3/4”.
Large bits are sharpened just like any other bit.
A large bit requires more half-turns to sharpen it.
It may take two or three complete sharpenings (repeat all steps)
to resharpen a very dull or chipped large drill bit. Using a optional
100-grit coarse wheel can speed up the process.
Short Drill Bits & Bit Smaller than 1/8”
Sharpen the small bit as usual, but use very light pressure and
an even number of turns. The bit should only briey contact the
wheel.
