Drill Doctor ® Maintenance - DRILL DOCTOR 360X Mode D'emploi

• You may have a specialty drill bit. Slow and fast spiral, helix,
turbo flutes, and raised margin drill bits are considered spe-
cialty bits. Your Drill Doctor does not sharpen these types of
bits.
• Follow the normal sharpening procedure. You may have to
realign and sharpen more than once to ensure that the bit is
sharpened correctly. If the problem persists contact the Techni-
cal Service Department.
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 halfturns 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 the Chuck is clean.
• Make sure the bit is not loose in the Chuck.
• During the sharpening process be sure to keep the same pres-
sure on each half-turn.
5. Question:
What can I do about flat spots on the bit point between the
Cutting Edge and the Heel?
Answer:
The flat spots on a sharpened bit are the result of an incomplete or
paused half-turn of the Chuck in the Sharpening Port. To correct,
apply light, inward pressure and rotate the Chuck smoothly while
sharpening. Be sure to complete the half-turns.

6. Question:
Why is the Chisel Edge on my drill bit flat?
Answer:
During the alignment process the Alignment Fingers may have
been gripping the high points of the drill bit. Reinsert the drill bit
in the Chuck making sure that the Alignment Fingers grip the nar-
rowest section of the bit (the flutes) and the Leading Edge of the
Flute is against the Alignment Finger. (See pages 10-11.)
7. Question:
Why does the drill bit back up into the Chuck during the sharp-
ening procedure?
Answer:
Make sure the bit is tight in the Chuck before sharpening. Your
Chuck may be dirty. Clean the Chuck as described on page 19.
8. Question:
Can I change a 135° drill bit into a 118° drill bit?
Answer:
You can change the point angle of any drill bit from 135° to 118°
by using normal sharpening procedures.

Drill Doctor Maintenance
After sharpening 20 to 25 drill bits, the drill bit grinding dust will
accumulate in the grinding compartment. Grinding particles will
promote wear in the Sharpening Port and Chuck, so cleaning on a
consistent basis can add life to your machine. Before any main-
tenance 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 forward. It will come com-
pletely off for easy access. To close, insert the Cover in the slots
and snap it back into place.
