Sharpening Bits of Different Lengths, Diameters,
and Types
Different size drill bits may require a different number of rotations.
Continue to sharpen until you no longer hear grinding noise.
Large Drill Bits
The Model DD500X sharpens bits from 3/32" to 1/2". You can also
purchase a Large Bit Chuck that sharpens bits up to 3/4". The
Model DD750X comes equipped with that Large-Bit Chuck. It
sharpens bits from 3/32" to 3/4".
Large bits are sharpened just like any other bit.
It is important to sharpen these bits so that the entire face of
the drill bit is sharpened. 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 an optional 100-grit coarse wheel can speed up the process.
