General Safety Rules
WARNING! Read and understand all instructions.
Failure to follow all instructions listed may result in
electric shock, re and/or serious injury. The term
“power tool” in all warnings listed herein refers to your
corded power tool.
WARNING! CHOKING HAZARD!
Small Parts – Not for children under 3-yrs.
Installation/Assembly
Carefully unpack the power tool and set it on the table. Check to
see that no damage has occurred in shipment. Check all packing
materials to be sure that all parts are present. See the section in
this User’s Guide for part identication diagram.
The Drill Doctor ® is completely assembled – it only needs to be
mounted securely to your workbench.
WARNING! Connect to properly wired (110V or 230V, as
applicable) outlet, or electrical shock may occur.
1. Work Area Safety:
a) Keep work area clean and well lit. Cluttered or dark areas
invite accidents.
b) Do not operate power tools in explosive atmospheres, such
as in the presence of ammable liquids, gases or dust. Power
tools create sparks which may ignite the dust or fumes.
c) Keep children and bystanders away while operating a power
tool. Distractions can cause you to lose control. Do not let
persons not involved in the work touch the tool or power
cord.
d) Make workshop kid proof with padlocks, master switches or
by removing starter keys.
e) Securely mount this tool to your workbench during use.
2. Electrical Safety:
DANGER! Electrical shock can kill! Read, understand and
follow ALL safety instructions.
WARNING! Do not expose power tools to rain or wet
conditions. Water entering a power tool will increase the
risk of electric shock.
a) Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any adapter plugs
with earthed (grounded) power tools. Unmodied plugs
and matching outlets will reduce risk of electric shock.

www.drilldoctor.com 5
b) Avoid body contact with earthed or grounded surfaces,
such as pipes, radiators, ranges and refrigerators. There
is an increased risk of electric shock if your body is earthed or
grounded.
c) Do not abuse the cord. Never use the cord for carrying,
pulling or unplugging the power tool. Keep cord away
from heat, oil, sharp edges or moving parts. Damaged or
entangled cords increase the risk of electric shock.
d) User proper extension cord. Use only 3-wire extension
cords that have 3-prong plugs and 3-pole receptacles that
accept the power tool’s plug. Make sure your extension cord
is in good condition. When using an extension cord, be sure
to use one heavy enough to carry the current your product
will draw. Use marked outdoor extension cord leads when
the tool is used outdoors.
e) Disconnect tools. Always disconnect your power tool when
cleaning, inspecting, and changing accessories. 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 result in injury.
f) Grounding instructions. In the event of a malfunction or
breakdown, grounding provides a path of least resistance for
electric current to reduce risk of electric shock. This power
tool is equipped with an electric cord having an equipment-
grounding conductor and grounding plug. Do not modify
the plug provided.The plug must be plugged into a matching
outlet that is properly installed and grounded in accordance
with all codes and ordinances. Improper connection of
the equipment-grounding conductor can result in a risk of
electric shock. The conductor with insulation having an outer
surface that is green with or without yellow stripes is the
equipment-grounding conductor. If repair or replacement
of the electric cord or plug is necessary, do not connect
the equipment-grounding conductor to the live terminal.
Check with a qualied electrician or service personnel if the
grounding instructions are not completely understood, or if
in doubt as to whether the tool is properly grounded. Repair
or replace damaged or worn cord immediately.
g) When operating a power tool outdoors, use an extension
cord suitable for outdoor use. Use of a cord suitable for
outdoor use reduces the risk of electric shock.

This tool is intended for use on a circuit that has an outlet
that looks like the one illustrated in Fig. A. It has a grounding
plug that looks like the one in Fig. B. A temporary adapter,
which looks like the adapter illustrated in Fig. C & Fig. D, may
be used to connect this plug to a 2-pole receptacle as shown
in Fig. D if a properly grounded outlet is not available. The
temporary adapter should be used only until a properly
grounded outlet can be installed by a qualied electrician.
The green-colored rigid ear, lug, and the like, extending
from the adapter must be connected to a permanent
ground such as a properly grounded outlet box.
3. Personal Safety:
Sharpening operations can create hot sparks and metal debris,
loud noises and dust.
a) Stay alert - watch what you are doing and use common
sense when operating a power tool. Do not use a power
tool while you are tired or under the inuence of drugs,
alcohol or medication. A moment of inattention while
operating power tools may result in serious personal injury.
b) Use personal protective equipment (PPE).
Always wear eye protection. Protective equipment
such as dust mask, non-skid safety shoes, hard
hat or hearing protection used for appropriate
conditions will reduce personal injuries.
c) Use ear protection during use. Drill Doctor ®unit can
generate in excess of 85 dB(A) noise emissions when in
operation.
d) Prevent unintentional starting. Ensure the switch is in
the o-position before connecting to power source and/
or battery pack, and when picking up or carrying the tool.
Carrying power tools with your nger on the switch, or
energizing power tools that have the switch on invites
accidents.
e) Remove any adjusting key or wrench before turning the
power tool on. A wrench or a key left attached to a rotating

www.drilldoctor.com 7
part of the power tool may result in personal injury.
f) Do no overreach. Keep proper footing and balance at
all times. This enables better control of the power tool in
unexpected situations. Nonslip footwear is recommended.
g) Dress properly. Wear closed, non-ammable protective
clothing. Do not wear loose clothing or jewelry. Keep your
hair, clothing and gloves away from moving parts. Loose
clothes, jewelry or long hair can be caught in moving parts.
h) Secure Work. Use clamps or a vise to hold work when
practical. It’s safer than using your hand and it frees both
hands to operate tool.
4. Power Tool Use and Care
WARNING! Use recommended accessories. Use the power
tool, accessories, abrasives, and tool bits etc., in accordance
with these instructions, taking into account the working
conditions and the work to be performed. Use of the power tool
for operations dierent from those intended could result in a
hazardous situation.
CAUTION! Keep power tools and work space clean for
best performance and safety. Do not let sharpening debris
accumulate on, in, or around the tool. Accumulated ne metal
sharpening debris can be very hot and may present a re danger
if the machine or your workspace is not properly cleaned and
maintained. Accumulated sharpening debris can also degrade the
life of the tool and cause premature wear on some components. If
sharpening debris has accumulated, do not immediately throw it
into a trash receptacle without ensuring the debris is completely
cool and free of heat. Improperly disposing of the accumulated
sharpening debris may present a re risk. Do not collect the
sharpening debris during sharpening. This increases the risk of
heat build-up in the debris and the potential for re.
a) Do not force the power tool or attachment. Use the correct
power tool for your application. Do not force small tools to
do the job of a heavy duty tool. The correct power tool will
job better and safer at the rate for which it is designed.
b) Use the right tool. Do not force tool or attachment to do a
job for which it is not designed.
c) Do not use the power tool if the switch does not turn it
on or o. Any power tool that cannot be controlled with the
switch is dangerous and must be repaired.
d) Never leave tool running unattended – Turn power o.
Do not leave the tool until it comes to a complete stop.
e) Disconnect the plug from the power source and/or the
battery pack from the power tool before making any
adjustments, changing accessories, or storing power

www.drilldoctor.com8
tools. Such preventative safety measures reduce the risk of
starting the power tool accidentally.
f) Store idle power tools out of reach of children and do
not allow persons unfamiliar with the power tool or
these instructions to operate the power tool. Power tools
are dangerous in the hands of untrained users.
g) Maintain power tools. Check for misalignment or binding
of moving parts, breakage of parts and any other condition
that may aect the power tool’s operation. If damaged, have
the power tool repaired before use. Keep unit dry, clean
and free from oil and grease. Many accidents are caused by
poorly maintained power tools.
h) Keep guards in place and in working order. 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.
i) Never stand on the power tool. Serious injury could
occur if the tool is tipped or if the sharpening edge is
unintentionally contacted.
j) Check damaged parts. Before further use of the tool, a
guard or other part that is damaged 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 aect 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 o. Do not use if the grinding wheel is damaged. Use
only grinding wheels recommended by Drill Doctor®.
5. Service
a) Have your tool serviced by a qualied repair person
using only identical replacement parts. This will ensure
that the safety of the power tool is maintained.

Specic Safety Rules
WARNING! ALWAYS use proper safety glasses. Everyday
eyeglasses are NOT safety glasses. Also use face of dust mask if
operation is dusty. ALWAYS wear certied safety equipment:
• ANSI Z87.1 eye protections (CAN/CSA Z94.3)
• ANSI 512.6 (53.19) hearing protection
• NIO5H/OSHA respiratory protection
WARNING! Use of this tool can generate and/or disperse
dust, which may cause serious permanent respiratory or other
injury. Always use NIOSH/OSHA approved respiratory protection
appropriate for the dust exposure. Direct particles away from face
and body.
WARNING! Avoid prolonged contact with dust from power
sanding, sawing, grinding, drilling, and other construction
activities. Wear protective clothing and wash exposed areas with
soap and water. Allowing dust to get into your mouth, eyes, or lie
on the skin may promote absorption of harmful chemicals.
Motor
Be sure your power supply agrees with the nameplate marking.
230 Volts AC only means your tool will operate on standard 50
HZ household power. Do not operate AC tools on DC. A rating of
230 volts AC/DC means that your tool will operate on standard 50
HZ AC or DC power. This information is printed on the nameplate.
Lower voltage will cause loss of power and can result in over-
heating.
Extension Cords
Make sure your extension cord is in good condition. When using
an extension cord, be sure to use one heavy enough to carry the
current your product will draw. An undersized cord will cause a
drop in line voltage resulting in loss of power and overheating.
The Drill Doctor® has a 1.75 ampere rating (.4 ampere in U.U.; .74
ampere in Japan). The following table shows the correct size to
use depending on cord length and nameplate ampere rating.
If in doubt, use the next heavier gauge. The smaller the gauge
number, the heavier the cord.

Identifying Basic Drill Bits
The Drill Doctor® is most ecient when used to resharpen 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.
Split Point
Split-point bits are self-centering and
are generally used for tempered steels,
hard alloys or hard cast materials.
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
When viewing a well-sharpened bit
from the side, the Heel will always be
lower than the Cutting Edge; this is
called “positive relief”.
When viewing a well-sharpened bit
from the end, the entire surface from
the Cutting Edge to the Heel will have
a nely ground surface without ridges
or indentations.

Aligning the Drill Bit
This makes sure that the Drill Doctor creates the right geometry.
It also sets the depth of the bit so that only a small amount of the
tip is taken o during sharpening.
Insert bit in Chuck and
tighten
Insert the bit into the Chuck Jaws and
close the Jaws just to the point where
the bit slides in and out. Do not over
tighten the Chuck; the bit needs to be
able to move in and out until Step 4.
1. Insert Chuck into Alignment Port
Press the Alignment Button down
and hold it. Match either of the
Alignment Guides (raised ns)
on the Chuck with the 118°
notch on the Alignment Port.
Insert the Chuck. While holding
the Alignment Button down,
slide the drill bit forward until
it touches the Drill Stop and the
Chuck is pushed all the way into
the Alignment Port. Release the
Alignment Button.

2. Adjust Bit Position
Look at the bit and make sure the Bit
Clamp Arms are in the bit’s narrowest
spot (the utes). If they aren’t, turn the
bit until it is. This is an important step
to proper alignment.
3. Tighten Chuck
Tighten the Chuck Knob. Avoid over
tightening the Chuck in the Alignment
Port. This could damage the Alignment
Port.
4. Remove and Re-tighten
Press the Alignment Button and remove
the Chuck from the Alignment Port.
Tighten the Chuck once more to ensure
the bit is held securely.
You are now ready to sharpen the drill
bit.

Sharpening the Bit
Before sharpening you should know:
•Keep the Chuck in constant contact with the Cam Pin 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.
•The Sharpening Port will rock as you turn the Chuck and it rides
on the Cam.
Align Guides
Turn the Drill Doctor on. Align either of the
Sharpening Guides (white
lines) with the Cam Pin
on the machine.
Insert Chuck and turn until sharp
Insert the Chuck in the Sharpening
Port. Making sure you keep the
chuck against the Cam Pin, rotate the
Chuck one half-turn in a clockwise
direction—from Sharpening Guide to
Sharpening Guide—an even number
of times. Your motion should be
smooth and even. Always sharpen
until there is no more grinding noise.
The number of turns needed to sharpen the bit depends
on the size.
Dierent size drill bits may require a dierent number of rotations.
Continue to sharpen until you no longer hear grinding noise. This
will result in a Chisel Edge that is clean and straight and the entire
surface from the Cutting Edge to the Heel is nely ground.

Identifying Correctly Sharpened Drill Bits
(and what to do with those that aren’t!)
Correctly Sharpened Bits
The entire surface from the Cutting
Edge to the Heel will have a nely
ground surface without ridges or
indentations. The Heel will always be
lower than the Cutting Edge (positive
relief).
Once you have reached spark-out (no more grinding noise at all)
take a look at your drill bit. The chisel angle should be at 1 o’clock
or 1:30.
Heel Cutting
Edge Chisel
Point
9:00
3:00
1:00
scribe
line
Look at the bit: Hold
the bit up and look at it
with the cutting edges
in line with the horizon
(or parallel with the
9:00 and 3:00 position
imagining a clock’s
face).
2:00 is too far advanced,
and if the chisel gets too
close to 12:00, the relief
will be negative.
Too much relief will cause an oversized hole diameter and rapid
bit wear. Too little relief will limit feed rates, slowing down the
drilling operation or in extreme cases cause the drill not to
perform at all.
If chisel angle looks to be about 2 o’clock, align bit 1-2 ticks on
the minus direction.
If chisel angle is up to about 2:30, align 2-3 ticks minus.
If chisel is about 12:45, it’s at the low end of chisel and relief,
align 1 tick to positive.

www.drilldoctor.com18
Split Points
Split point drill bits prevent walking on the material before they
begin to cut. This feature is described as self-centering. The need
to center punch is eectively eliminated. A standard drill bit chisel
point has to wear an area in the middle of the hole to be drilled
before the cutting edges will remove material. Due to its addition-
al cutting lips along the chisel edge, a split point will begin cutting
immediately. Up to 70% less thrust (when compared to a non-split
or conventional point) is required to drill a hole with a split point.
Optional Step: Splitting the Point
1. Leave bit in chuck after
sharpening
Always align and sharpen a bit before
splitting it. To split the point, do not
remove the bit from the Chuck after
sharpening.
2. Remove the Grit Tube
3. Align Guides
Align one of the Sharpening Guides
on the Chuck (white lines) with the
Splitting Guide on the Splitting Port.

www.drilldoctor.com 19
4. Split the point
Press Chuck slowly and rmly into
the Splitting Port. Remove the chuck,
rotate one-half turn, and repeat.
Check the tip of the bit carefully to
determine that both sides of the
bit are split equally. Compare it to
this illustration. If it does not match,
study the information below.
Identifying Correctly Split Drill Bits
(And What to Do With Those That Aren’t!)
Correctly Split
Split lines are nearly straight across.
Solution
More grinding is needed for larger
drill bits. If one side of the bit is
under split, insert the Chuck into the
Splitting Port again and split both
sides. Repeat until the split sides are
equal and look like the correctly split
bit shown above.

Split Line
Split lines do not meet
in the center but
Chisel Edge remains.
Not enough material
has been removed
from the Heel of
the drill bit.
Undersplit

www.drilldoctor.com20
Oversplit
Solution
Reinsert the chucked bit into the
Sharpening Port and remove enough
of the tip until the split tip looks like
the correctly split bit above.
Grit Tube Attachment
The Grit Tube attachment is
designed to keep any sparks
caused by sharpening safely
inside the machine and away
from you. In addition, the Grit
Tube reduces the sharpening
dust in the air and on your
workbench.
Simply insert the Grit Tube
into the Splitting Port of
your Drill Doctor when
sharpening. It will catch the grit that is formed from the sharpening
process. Clean the inside of your Drill Doctor and the Grit Tube on
a regular schedule. The grit tube is designed to accept a standard
1-1/4” shop vacuum for extended periods of sharpening.
