Drill Doctor Maintenance - DRILL DOCTOR 350X Mode D'emploi

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 narrowest section of the bit (the flutes)
and the Leading Edge of the Flute is against the Align-
ment Finger. (See page 7-8.)
7. 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. Clean the Chuck as described on
page 17.
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. 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 forward. It
will come completely off for easy access. To close, insert
the Cover in the slots and snap it back into place.

Cleaning Your Drill Doctor
With the Drill Doctor unplugged, shake accumulated
drill bit grinding dust from behind the Wheel Access Cover
into a disposable container. Remove dust particles around
the wheel with a small, dry brush. Dispose of the
container and drill bit dust in a safe and environmentally
approved manner. With a dry cloth wipe the inside and
outside of the Sharpening Port to remove any grinding
dust that may have accumulated. A standard 1" vacuum
hose works equally well.
Cleaning the Chuck
Unscrew the Knob from the body and clean both threads
with a soft brush or cotton swab. Re-assemble the Chuck
and operate the Knob through its travel to ensure it turns
freely. When the
Chuck Jaws
Knob is removed, be
careful not to lose
the small springs
that separate the
Chuck Jaws.
Determining if Replacing
the Diamond Grinding Wheel
Is Required
You can double the life of the Diamond Sharpening Wheel
by reversing it before you replace it. The Diamond Sharp-
ening Wheel supplied with the Drill Doctor is designed to
give you long and trouble free service, with an average of
more than 200 sharpenings for 3/32" to 1/2" drill bits.
The Sharpening Wheel may need to be changed if:
1. Sharpened drill bits burn or turn blue no matter how
fast or slow you rotate the Chuck.
2. When touching the Sharpening Wheel (with the
machine unplugged), the lower portion feels too
smooth (nonabrasive).
3. When sharpening the drill bit, it takes too many half-
turns to sharpen.
Contact the store or dealer where you purchased the Drill
Doctor, or contact Drill Doctor directly, to purchase a
replacement Sharpening Wheel.
