Note:
The Drill Doctor will place a curved grind on the carbide
insert, altering the appearance of the factory point.

Now, sharpen the bit in the
Sharpening Hole. Always use an
even number of half-turns when
sharpening. Start with four half-
turns and then add as many half-
turns as needed.
While looking through the win-
dow, start with the carbide tip of
the bit straight up and down, and
then turn it 1/8 turn to the right
(the carbide tip should point to
between the 1:00 and 2:00
o’clock position when looking at
a clock face).
Push the Alignment Button back
to the housing and
hold it in
through Step 4
. Insert the
chucked drill bit to the
stop.
Bit Clamps are
not used when
aligning masonry
bits
.
Insert your masonry bit in the
Chuck in the same manner as
other bits (See page 5).
Tighten the Chuck Knob and
remove the chuck from the Align-
ment Hole. Release the Align-
ment Button and tighten the
Chuck.
