Drill Doctor 750x drill bit sharpener Mode D'Emploi

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.

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.

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.

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.

, 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.

, shake accumulated

drill bit grinding dust from behind the Wheel 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.
You can also use the Grit Tube attachment as shown on
page 16.

With compressed air, blow out the Chuck from the Knob
end or brush out with a small, dry brush. 

You can double the life of the Diamond Sharpening Wheel
by reversing it before you replace it. The Sharpening
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 Diamond Sharpening Wheel may need to be changed if:
• Sharpened drill bits burn or turn blue no matter how fast

or slow you rotate the Chuck.

• When touching the Sharpening Wheel (with the machine

unplugged), the lower portion feels too smooth
(nonabrasive).

• 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.
