Identifying Basic Drill Bits
The Drill Doctor®is most efficient when used to sharpen a drill
bit’s original point angle.With its standard diamond sharpening
wheel it will sharpen high-speed steel, cobalt, TiN-coated,
carbide and masonry drill bits.
It has been designed and engineered to sharpen three of the
most common drill bit types:
Standard Point
This general purpose point (normally
118°) is used for drilling softer
materials like cold rolled steel,
aluminum, and wood.
Masonry bits (normally 135°) have
a carbide insert at the point and are
used for drilling materials like cement,
brick, and ceramic.
Split point bits (normally 135+°)
are self-centering and are generally
used for tempered steels, hard alloys
or hard cast materials.
Anatomy of a Drill Bit
It is important to understand that
each bit has a Chisel Edge, a Cutting
Edge, a Heel, and a Relief Angle.
When viewing a well sharpened bit
from the end, the entire surface from
the Cutting Edge to the Heel will have
a finely ground surface without ridges
or indentations.The Heel will always be
lower than the Cutting Edge.

The Drill Doctor®Sharpening Process
The sharpening process includes 2 easy procedures:
1. Align the bit in the Chuck.
2. Sharpen the bit.
Aligning the Drill Bit
(See page 11 to align and sharpen a Masonry drill bit.)
4.
1. Turn the Chuck Knob to the left
to open the Chuck and insert
your drill bit into the Chuck
(about halfway in is fine for
now).
Turn the Chuck Knob to the right
to tighten.
Turn the Chuck Knob to the left
just until the bit will slide and
rotate in the Chuck.
With one hand, press in and
hold the Alignment Button on
the Drill Doctor (do not release
until Step 7).

Flat Spots
5.
With your free hand, insert the
Chuck into the Alignment Port—
make sure the flat spots on the
Chuck match the flat spots in the
port.
At this point, the Chuck
should be inserted into the
Alignment Port with the
flat spots hidden, and the
Chuck should be locked in the port.
6.
8.
With the Alignment Button held
in, push the drill bit forward until
it is against the Drill Stop.
Look at the drill bit through
the Window over the
Alignment Port—it should be
against the Drill Stop.
Release the Alignment Button
and hold the chuck in place with
your thumb.
While looking in the Window,
turn the drill bit to the right until
you feel the Bit Clamps grip
the bit at its narrowest
point (the bit is now difficult
to turn either way).

Sharpening the Drill Bit
Before sharpening you should know:
•Keep the Cam in contact with the Cam Guide as you
sharpen—push the Chuck straight into the port.
•Only light pressure is required—let the diamond wheel do
its work.
•Turn the Chuck an even number of half-turns:
3/32 inch bits—use 2 to 4 half-turns,
1/8 inch bits—use 4 to 6 half-turns,
3/8 inch bits—use 16 to 20 half-turns.
•You will hear a grinding noise as you complete each half-
turn and each side of the bit face is ground. (zzzzzzzzz)
•The Chuck will rock as you turn it and the Cam rides on the
Guide.
13.
12.
Insert the Chuck into the
Sharpening Port.
It will be easier to sharpen the
bit if you stand up.
Align one of the white marks on
the Cam with the Cam Guide,
and push the Power
Switch to the ON (I)
position.
14. Turn the Chuck in complete half-
turns to the right so the white
marks on the Chuck move to the
Cam Guide one after the other.
It is important that your half-
turns be continuous—do not
stop or hesitate in the middle.
