en the bit. If your drill bit is quite dull or damaged, turn
the Material Take-Off Knob counter-clockwise to increase
the amount of material removed. Your MTO adjusts from 0
to .040 of an inch in increments of .005. Prior to aligning
the bit, turn the MTO Knob counter-clockwise until it
stops. (This is the maximum material that can be removed
in one sharpening.) Then turn it clockwise 3 marks on the
MTO knob. This is a good place to start for most bits.
Now turn the MTO knob either direction to adjust the
desired MTO. Each mark on the MTO knob is equal to
.005" change in material removed from the bit.
Note: After you have sharpened your bits on the Drill Doc-
tor at least one time, it is desirable to turn the MTO Knob
such that only a small amount of material is removed from
the bit each time you sharpen. This will significantly
decrease the time to sharpen as well as extend your bit
and wheel life. Once you've made your adjustment, align
and sharpen your bit as usual.
