Drill Doctor Maintenance - Drill Master 750X User Manual

9. Question:
Why does the drill bit back up into the Chuck during
the sharpening procedure?
Answer:
Make sure the bit is tight in the Chuck before sharpening.
Your Chuck may be dirty. Follow the steps for cleaning the
Chuck on page 25.
10. Question:
When splitting, why don't I hear a grinding sound?
Answer:
The Chuck is not seated properly in the Splitting Port. The
Chuck's Sharpening Guide must line up with the Splitting
Guide on the top of the Split Point Port. Firmly and slowly
push the Chuck into the hole until the grinding sound
stops.
11. Question:
Can I change a 135° drill bit into a 118° drill bit?
Answer:
You can change the degree angle of any drill bit from 135°
to 118°. The alignment and sharpening procedure will
need to be performed three or more times to remove the
old angle and produce the new angle desired.

Drill Doctor Maintenance

After sharpening 20 to 25 drill bits, the drill bit grinding
dust will accumulate in the grinding compartment. Grind-
ing particles will promote wear in the Sharpening Port
and Chuck, so cleaning on a consistent basis can add life
to your machine. Before any maintenance or cleaning is
performed, be sure to disconnect your Drill Doctor.
Removing the Wheel Access Cover
With the Drill Doctor unplugged, use your nail or the tip
of your finger to pull the Wheel Access Cover down. It will
come completely off for easy access. To close, insert the
Cover in the slots and snap it back into place.
