Precautions
When using electric tools, basic safety precautions should
always be followed to prevent the risk of fire, electric
shock, and personal injury.
• KEEP WORK AREA CLEAN. Cluttered areas and
bench invite accidents.
• DO NOT USE IN DANGEROUS ENVIRONMENT. Do
not use in damp or wet locations, avoid exposure to
rain. Keep work area well lit. Do not use tools in the
presence of flammable liquids or gases.
• GUARD AGAINST ELECTRIC SHOCK. Avoid body
contact with earthed or grounded surfaces (e.g., pipes,
radiators, ranges, refrigerators).
• KEEP OTHER PERSONS AWAY. Do not let persons,
especially children, not involved in the work touch the
tool or the extension cord and keep them away from
the work area.
• STORE IDLE TOOLS. When not in use, tools should be
stored in a dry, locked-up place out of the reach of children.
• DO NOT FORCE THE TOOL. It will do the job better
and safer at the rate for which it was intended.
• DRESS PROPERLY. Do not wear loose clothing or jew-
elry; they can be caught in moving parts. Wear protective hair covering to contain long hair.
• USE PROTECTIVE EQUIPMENT. Use safety glasses.
Use face or dust mask if working operations create
dust.
• DO NOT ABUSE THE CORD. Never yank the cord to
disconnect it from the socket. Keep the cord away from
heat, oil and sharp edges.
• MAINTAIN TOOL WITH CARE. Keep the Drill Doc-
tor
®
clean for best and safest performance. Follow
instructions for maintenance and changing accessories. Inspect cords periodically and if damaged have
them repaired by an authorized service facility. Inspect
extension cords periodically and replace if damaged.
Keep unit dry, clean and free from oil and grease.
• DISCONNECT TOOLS. Always disconnect the Drill
Doctor
®
when cleaning, inspecting, and changing
accessories, such as the diamond sharpening wheel.
When not in use, disconnect from the power supply.
Never touch internal parts of the sharpener when it is
turned on or plugged in. The rotating diamond wheel
can cause injury.
• AVOID UNINTENTIONAL STARTING. Make sure
switch is in the “OFF” position before plugging in.
• STAY ALERT. Watch what you are doing, use common
sense and do not operate the tool when you are tired.
• CHECK DAMAGED PARTS. Before use of the tool, it
should be carefully checked to determine that it will
operate properly and perform its intended function.
Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting and any other
conditions that may affect its operation. A guard or
other part that is damaged should be properly repaired
or replaced by an authorized service center unless otherwise indicated in the instruction manual. Have defective switches replaced by an authorized service center.
Do not use the tool if the switch does not turn it on and
off. Do not use if the grinding wheel is damaged. Use
only grinding wheels recommended by Drill Doctor

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.
The Model 350X has been designed and engineered to
sharpen the most common drill point types:
Standard Point
This general-purpose point (normally 118°) is used for drilling
softer materials like cold rolled
steel, aluminum, and wood.
Masonry Bits
Masonry bits have a carbide
insert at the point and are used
for drilling materials like cement,
brick, and ceramic.
Anatomy of a Drill Bit
Chisel
Edge
It is important to understand that
each bit has a Chisel Edge, a Cutting Edge, a Heel, a Relief Angle,
and a Leading Edge. (The Leading Edge will be important in bit
alignment.)
Cutting
Edge
Heel
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; this
is called positive relief.

The Drill Doctor®Sharpening Process
The sharpening process includes 2 easy procedures:
1. Aligning the bit in the Chuck.
2. Sharpening the bit.
Aligning the Drill Bit
This makes sure that the Drill Doctor creates the right
geometry. It also sets the bit so that only a small amount
of the tip is taken off during sharpening.
(See page 12-13 to align and sharpen a masonry drill bit.)
Insert bit in Chuck.
Hold the Chuck with the
White Triangle facing up.
Insert the bit into the front of
the Chuck, leaving 1/2" of bit
sticking out the front.
2.
Tighten Chuck slightly.
Tighten the Chuck by turning
the Chuck Knob clockwise
just to the point where the bit
is snug but can still be slid in
and out. The Chuck should
not be completely tightened
until we set the bit depth for
sharpening in the next step.
Rotate the drill bit in the
Chuck so that the Leading
Edge of the flute is against
the Alignment Finger. This
aligns the bit for accurate
sharpening.
Note: A good test to see if the
Chuck is tightened the correct amount is to make sure
it moves when you pull on it
with your fingers, but will not
fall out when you turn the
Chuck upside down.

3.
Set depth of bit and
tighten Chuck.
With the machine turned
off, align the White Triangle
on the Chuck with the Cam
Guide. While keeping the
Chuck against the Cam Guide
on the 350X, insert the
Chuck into the Sharpening
Port. Push the Chuck all the
way into the Port.
Tighten the Chuck Knob
while it’s still in the Sharpening Port.
Remove the Chuck and make
sure it is tight so the bit
won’t move when you sharpen it.

Sharpening the 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.
• You will hear a grinding noise
(zzzzzzzzz) as you
complete each half-turn and each side of the bit face is
ground.
• The Chuck will rock as you turn it and the Cam rides
on the Guide.

Turn on the Model 350X.
Align either of the Sharpening Guides on the Chuck with
the Cam Guide and insert the
Chuck in the Sharpening
Port.
Sharpening Guide
2.
Turn until sharp.
Making sure that the Chuck
rests firmly against the Cam
Guide, turn the Chuck one
half-turn to the right—to the
other Sharpening Guide.
Turn from Guide to Guide in a
smooth and even motion until
the bit is sharp. To sharpen
both sides of the bit evenly,
always use an even number
of half-turns. The number of
half-turns needed to sharpen
the bit depends on its size.
Turn the Chuck an even number of half-turns with light
inward pressure:
• 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.
Note: Use just enough pressure to keep the Cam against
the Cam Guide. Let the machine do the sharpening.

Identifying Correctly Sharpened Drill Bits
(and what to do with those that aren’t!)
Correctly Sharpened Bits
Chisel Point
Cutting Edge
Heel
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 (positive relief).
Problem
The Chisel Edge
is ground flat.
Cause
Alignment Fingers did not
position the drill bit properly
in the aligning process (page
7-8).
Solution
Realign the bit by carefully following steps 1 through 3 on
page 7-8.
Cause
Too much drill bit is sticking out of
the end of the chuck.
Solution
Realign the bit. During the re-alignment process, be sure to keep the
White Triangle against the Cam
Guide as you insert the Chuck into
the Sharpening Port to set the depth
of the bit. The bit should be pushed
up inside the Chuck and should
rotate slightly as the Chuck is
plunged into the Sharpening Port
and contacts the Diamond Sharpening Wheel. Push until the Chuck is
fully inserted into the Port.
Problem
Surface of the
bit isn’t smooth
and/or heavy
grinding sound.
Problem
Heel same height or higher
than the cutting edge
Cause
Bit is misaligned or the Cam
failed to stay in contact with
the Cam Guide during sharpening.
Solution
Carefully repeat the alignment
and sharpening procedure,
making sure to use light pressure to keep the Cam in contact
with the Cam Guide during
sharpening.
Cutting Edge
Heel
Relief Angle
Problem
Cause
Too much pressure during
sharpening, dirty Chuck, or
Chuck not tightened enough.
Solution
Use just enough pressure to
keep the Cam in contact with
the Cam Guide. If the bit continues to slip, clean the Chuck
as described on Page 17.

Sharpening Bits of Different
Lengths and Diameters
Drill Bits Of Different Sizes
Too many rotations of a small-diameter bit may result in
incorrect sharpening and too few on a large bit may not
sharpen enough.
• 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.
www.drilldoctor.com 1312 www.drilldoctor.com
Large Drill Bits
Large drill bits (3/8" to 1/2") will require more half-turns
of the Chuck. A well-sharpened bit will have a smooth surface from Cutting Edge to Heel. It may take two or three
complete sharpenings (repeat all steps) to re-sharpen a
very dull or chipped large drill bit. A 1/2" bit will need a
minimum of 20 half-turns.
Short Drill Bits
The new Chuck design on the 350X enables you to sharpen short bits as easily as longer ones. Simply align the bit
in the Chuck as normal. Then sharpen the bit using very
light pressure and fewer half-turns. The bit should only
briefly contact the Sharpening Wheel. Note that it is OK
for the Chuck Fingers to come into contact with the
Sharpening Wheel. This will not damage the Chuck.
Aligning and Sharpening
Masonry Drill Bits
To sharpen a masonry bit, you do not turn the Chuck.
Instead you insert the Chuck until it touches the wheel,
remove, and repeat on the other side.
1.
2.
Tighten
Tighten the Chuck while
checking that the insert is
touching the end of the Alignment Fingers. Tighten until
the bit no longer moves in the
chuck
3.
Plunge until sharp.
Align the White Triangle on
the Chuck with the Cam
Guide on the machine.
Plunge the Chuck into the
Sharpening Port until it contacts the Sharpening Wheel.
Remove the Chuck and rotate
one half-turn to the opposite
White Triangle. Plunge the
Chuck into the Sharpening
Port again to sharpen the
other side of the carbide
insert. Start with four
plunges. Inspect the bit.
Then sharpen more if needed.

Questions and Answers
1. Question:
Why was my drill bit sharpened improperly?
Answer:
The most common cause of improper sharpening is
improper drill bit alignment.
Key causes are:
1. Chuck not pushed all the way into the Sharpening
Port.
2. Drill not aligned in the Alignment Fingers correctly.
4. Chuck is dirty and the bit slipped out of alignment. See
page 17, “Cleaning the Chuck,” to correct.
5. Too many rotations of a small-diameter bit results in
incorrect sharpening, and too few on a large bit may
not sharpen enough. See page 11–12, “Drill Bits of Different Sizes.”
In order to correct these problems be sure the Chuck is all
the way in the Sharpening Port with the Guides correctly
matched up.
2. Question:
When I aligned the drill bit and sharpened it, why was
no material removed?
Answer:
This happens when the bit is not protruding out of the
Chuck far enough. The Chuck may not have been tightened
enough and the bit may have slipped in the Chuck.
Carefully realign the bit in the Chuck and set its depth in
the Sharpening Port again.
3. Question:
I sharpened the bit. Why will it not cut?
Answer:
This happens when the Heel on the bit is higher than the
Cutting Edge (negative relief). Realign the drill bit and
resharpen in the Sharpening Port.
• Maintain consistent inward light pressure during the
half-turns of the Chuck.
•You may have a specialty drill bit. Slow and fast spiral,
helix, turbo flutes, and raised margin drill bits are considered specialty bits. Your Drill Doctor does not
sharpen these types of bits.
• Follow the normal sharpening procedure. You may
have to realign and sharpen more than once to ensure
that the bit is sharpened correctly. If the problem persists contact the Technical Service Department.
4. Question:
Why is the drill point off center?
Answer:
If the tip of the drill bit appears to be sharpened off center,
check the following items:
•You may not have completed an even number of halfturns when you sharpened and one face of the bit was
ground more than the other. Always use an even number of half-turns when you sharpen.
• Make sure the Chuck is clean.
• Make sure the bit is not loose in the Chuck.
• During the sharpening process be sure to keep the
same pressure on each half-turn.
5. Question:
What can I do about flat spots on the bit point between
the Cutting Edge and the Heel?
Answer:
The flat spots on a sharpened bit are the result of an incomplete or paused half-turn of the Chuck in the Sharpening
Port. To correct, apply light, inward pressure and rotate the
Chuck smoothly while sharpening. Be sure to complete the
half-turns.
www.drilldoctor.com 1716 www.drilldoctor.com
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 Alignment 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. Grinding 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
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 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 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 halfturns to sharpen.
Contact the store or dealer where you purchased the Drill
Doctor, or contact Drill Doctor directly, to purchase a
replacement Sharpening Wheel.
