Drill Doctor 750x drill bit sharpener Mode D'Emploi

Hold onto the Chuck and
tighten the Chuck Knob.
(Avoid over-tightening the
Chuck in the Alignment Port.
This could damage the Chuck
and Port.)

Press the Alignment Button
and remove the chucked drill
bit. Tighten the Chuck once
more to ensure the bit won’t
move when you sharpen it.
You are now ready to sharpen
the drill bit.

Before sharpening you should know:

•

—push the Chuck straight into the Port.

•

Only light pressure is required.

Cam Guide

Turn the Drill Doctor on.
Align either of the Sharpen-
ing Guides with the Cam
Guide on the machine.

Cam

Insert the Chuck in the
Sharpening Port. Making
sure you keep the Cam
against the Cam Guide,
rotate the Chuck one half-
turn in a clockwise direc-
tion—from Sharpening Guide

to Sharpening Guide—an
even number of times. Your
motion should be smooth and

even. To sharpen both sides of the bit evenly, always use
an even number of half-turns. The number of turns needed
to sharpen the bit depends on the size.
Turn the Chuck an even number of half-turns with light
inward pressure:

—use 2 to 4 half-turns, 

—use 4 to 6 half-turns, 

—use 16 to 20 half-turns.

Use just enough pressure to keep the Cam against

the Cam Guide. Let the machine do the sharpening.

Sharpening

Guide

Look at your bit and make
sure the Clamp Arms are in
the bit’s narrowest spot. If
they aren’t, turn the bit in the
chuck so that it is held by the
Bit Clamp Arms at the nar-
rowest width. This is impor-
tant because this setting
determines the angle at which
your bit will be sharpened.
