Work area safety

Keep work area clean and well lit. Cluttered

or dark areas invite accidents.

Do not operate power tools in explosive
atmospheres, such as in the presence of

flammable liquids, gases or dust. Power

tools create sparks which may ignite the dust
or fumes.

Keep children and bystanders away while

operating a power tool. Distractions can

cause you to lose control.

Electrical safety

Power tool plugs must match the outlet.
Never modify the plug in any way. Do not
us e any ada p ter plug s wi t h ea rthe d

(grounded) power tools. Unmodified plugs

and matching outlets will reduce risk of electric
shock.

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.

Do not expose power tools to rain or wet

conditions. Water entering a power tool will

increase the risk of electric shock.

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.

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.

If operating a power tool in a damp location
is unavoidable, use a Ground Fault Circuit

Interrupter (GFCI) protected supply. Use of

an GFCI reduces the risk of electric shock.

Personal safety

Stay alert, watch what you are doing and
us e commo n sen se wh en op erating a
power tool. Do not use a power tool while
you are tired or under the influence of drugs,

alcohol or medication. A moment of inattention

while operating power tools may result in
serious personal injury.

Use personal protective equipment. Always

Read all safety warnings and all instructions. Failure to follow the warnings

and instructions may result in electric shock, fire and/or serious injury.

SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE

The term “power tool” in the warnings refers to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.

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.

Prevent unintentional starting. Ensure the
sw itch is in th e off-p ositi on befo re
connecting to power source and / or battery
pa ck, picking up or ca rrying the too l.

Carrying power tools with your finger on the
switch or energizing power tools that have the
switch on invites accidents.

Remove any adjusting key or wrench before

turning the power tool on. A wrench or a key

left attached to a rotating part of the power
tool may result in personal injury.

Do not overreach. Keep proper footing and

balance at all times. This enables better

control of the power tool in unexpected
situations.

Dress properly. 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.

If devices are provided for the connection
of dust extraction and collection facilities,
ensure these are connected and properly

used. Use of dust collection can reduce dust-

related hazards.

Power tool use and care

Do no t f orc e t he pow er too l. Use the

correct power tool for your application. The

correct power tool will do the job better and
safer at the rate for which it was designed.

Do not use the power tool if the switch does

not turn it on and off. Any power tool that

cannot be controlled with the switch is
dangerous and must be repaired.

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 tools. Such

preventive safety measures reduce the risk of
starting the power tool accidentally.

Store idle power tools out of the 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.

Maintain power tools. Check for misalignment
or binding of moving parts, breakage of
parts and any other condition that may
affect the power tool’s operation. If damaged,
have the power tool repaired before use.

Many accidents are caused by poorly
maintained power tools.

Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to
control.

Use the power tool, accessories 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 different from those
intended could result in a hazardous situation.

Service

Have your power tool serviced by a qualified
re pair p erso n usin g only i dent ical

replacement parts. This will ensure that the

safety of the power tool is maintained.

Safety warnings common for

grinding, sanding, wire brushing,

polishing, carving or abrasive

cutting-off operations:

This power tool is intended to function as a
gr inder, sande r, w ire brush, pol ish er,
carving or cut-off tool. Read all safety
warnings, instructions, illustrations and
specifications provided with this power

tool. Failure to follow all instructions listed

below may result in electric shock, fire and/or
serious injury.

Do not use accessor ie s which are not
specifically designed and recommended by

the tool manufacturer. Just because the

accessory can be attached to your power tool,
it does not assure safe operation.

The R ATED SPEED of the accessories
must be at least equal to the maximum
sp eed ma rke d on the pow er too l.

Accessories running faster than their RATED
SPEED can break and fly apart.

The outside diameter and the thickness of
your accessory must be within the capacity

rating of your power tool. Incorrectly sized

accessories cannot be adequately guarded or
controlled.

The arbor size of wheels, sanding drums or

any other accessory must properly fit the
sp ind le or co lle t of the p owe r too l.

Accessories that do not match the mounting
hardware of the power tool will run out of
balance, vibrate excessively and may cause
loss of control.

Mandrel mounted wheels, sanding drums,
cutters or other accessories must be fully

inserted into the colle t or chuck. If the

mandrel is insufficiently held and/or the
overhang of the wheel is too long, the mounted
wheel may become loose and be ejected at
high velocity.

Do not use a damaged accessory. Before
each use inspect the accessory such as
abrasive wheels for chips and cracks,
sanding drum for cracks, tear or excess
wear, wire brush for loose or cracked wires.
If power tool or accessory is dropped,
inspect for damage or install an undamaged
accessory. After inspecting and installing
an a cce ssory, p osition yourself and
bystanders away from the plane of the
rotating accessory and run the power tool
at maximum no-load speed for one minute.

Damaged accessories will normally break apart
during this test time.

Wear pers onal prote ctive equi pme nt.
Depending on application, use face shield,
sa fety go ggles or safet y glasses. As
ap propr iat e, w ear dus t mask, hearin g
protectors, gloves and workshop apron
capabl e of stopping small abrasi ve or
workpiece fragments. The eye protection
must be capable of stopping flying debris

generated by various operations. The dust

mask or respirator must be capable of filtrating
particles generated by your operation.
Prolonged exposure to high intensity noise may
cause hearing loss.

Keep bystanders a safe distance away from
work area. Anyone entering the work area
must wear personal protective equipment.

Fragments of workpiece or of a broken
accessory may fly away and cause injury
beyond immediate area of operation.

Hold the power tool by insulated gripping
su rface s on ly, whe n pe rform ing an
operation where the cutting accessory may
conta ct hidden wiring or its own cord.

Cutting accessory contacting a “live” wire may
make exposed metal parts of the power tool
“live” and could give the operator an electric
shock.

Always hold the tool firmly in your hand(s)

during the start-up. The reaction torque of the

motor, as it accelerates to full speed, can cause
the tool to twist.

Use clamps to support workpiece whenever
practical. Never hold a small workpiece in
one hand and the tool in the other hand

while in use. Clamping a small workpiece

allows you to use your hand(s) to control the
tool. Round material such as dowel rods, pipes
or tubing have a tendency to roll while being
cut, and may cause the bit to bind or jump
toward you.

Position the cord clear of the spinning

accessory. If you lose control, the cord may be

cut or snagged and your hand or arm may be
pulled into the spinning accessory.

Never lay the power tool down until the
accessory has come to a complete stop.

The spinning accessory may grab the surface
and pull the power tool out of your control.

After changing the bits or making any
adjustments, make sure the collet nut,
chuck or any other adjustment devices are

securely tightened. Loose adjustment devices

can unexpectedly shift, causing loss of control,
loose rotating components will be violently
thrown.

Do not run the power tool while carrying it

at your side. Accidental contact with the

spinning accessory could snag your clothing,
pulling the accessory into your body.

Regularly clean the power tool’s air vents.

The motor’s fan will draw the dust inside the
housing and excessive accumulation of
powdered metal may cause electrical hazards.

Do n ot operate t he po wer tool nea r

flammable materials. Sparks could ignite

these materials.

Do not use accessories that require liquid

coolants. Using water or other liquid coolants

may result in electrocution or shock.
Use only in well-ventilated area. Working in a

safe environment reduces risk of injury.

Allow f or sufficient space, at least 6”,
between your hand and the spinning bit. Do

not reach in the area of the spinning bit. The

proximity of the spinning bit to your hand may
not always be obvious.

Do not touch the bit or collet after use. After
use the bit and collet are too hot to be touched
by bare hands.

Do not alter or misuse tool. Any alteration or

modification is a misuse and may result in
serious personal injury.

This product is not intended for use as a
dental drill, in human or veterinary medical

applications. Serious injury may result.

Kickback and Related Warnings

Kickback is a sudden reaction to a pinched or
snagged rotating wheel, backing pad, brush or
any other accessory. Pinching or snagging
causes rapid stalling of the rotating accessory
which in turn causes the uncontrolled power
tool to be forced in the direction opposite of the
accessory’s rotation.

For example, if an abrasive wheel is snagged
or pinched by the workpiece, the edge of the
wheel that is entering into the pinch point can
dig into the surface of the material causing the
wheel to climb out or kickout. The wheel may
either jump toward or away from the operator,
depending on direction of the wheel’s
movement at the point of pinching. Abrasive
wheels may also break under these conditions.

Kickback is the result of power tool misuse
and/or incorrect operating procedures or
conditions and can be avoided by taking proper
precautions as given below.

Maintain a firm grip on the power tool and
position your body and arm to allow you to

resist kickback forces. The operator can

control kickback forces, if proper precautions
are taken.

Use special care when working corners,
sh arp edg es et c. Avoid bo unc ing and

snagging the accessory. Corners, sharp

edges or bouncing have a tendency to snag the
rotating accessory and cause loss of control or
kickback.

Do not attach a toothed saw blade. Such
blades create frequent kickback and loss of
control.

Always feed the bit into the material in the
same direction as the cutting edge is exiting
fr om the mat eri al (which is the same

direction as the chips are thrown). Feeding

the tool in the wrong direction causes the
cutting edge of the bit to climb out of the work
and pull the tool in the direction of this feed.

When using rotary files, cut-off wheels,
high-speed cutters or tungsten carbide
cutters, always have the work securely

clam ped. These wheels will grab if they

become slightly canted in the groove, and can

kickback. When a cut-off wheel grabs, the
wheel itself usually breaks. When a rotary file,
high-speed cutter or tungsten carbide cutter
grabs, it may jump from the groove and you
could lose control of the tool.

Safety warnings specific for

grinding and abrasive

cutting-off operations:

Us e on ly w heel ty pes that ar e
recommended for your power tool and only
fo r r eco mmend ed ap pli catio ns. For
example: do not grind with the side of a cut-

off wheel. Abrasive cut-off wheels are intended

for peripheral grinding, side forces applied to
these wheels may cause them to shatter.

For threaded abrasive cones and plugs use
only undamaged wheel mandrels with an
unre lieved s houlder flang e that are of

correct size and length. Proper mandrels will

reduce the possibility of breakage.

Do not ′′jam′′ a cut-off wheel or apply
excessive pressure. Do not attempt to make

an excessive depth of cut. Overstressing the

wheel increases the loading and susceptibility
to twisting or snagging of the wheel in the cut
and the possibility of kickback or wheel
breakage.

Do not position your hand in line with and

behind the rotating wheel. When the wheel,

at the point of operation, is moving away from
your hand, the possible kickback may propel
the spinning wheel and the power tool directly
at you.

When wheel is pinched, snagged or when
interrupting a cut for any reason, switch off
the power tool and hold the power tool
motionless until the w he el comes to a
complete stop. Never attempt to remove the
cut-off wheel from the cut while the wheel is
in motion otherwise kickback may occur.

Investigate and take corrective action to
eliminate the cause of wheel pinching or
snagging.

Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed

and carefully re-enter the cut. The wheel may

bind, walk up or kickback if the power tool is
restarted in the workpiece.

Support panels or any oversized workpiece
to minimize the risk of wheel pinching and

kickback. Large workpieces tend to sag under

their own weight. Supports must be placed

GFCI and personal protection devices like
electrician’s rubber gloves and footwear will
further enhance your personal safety.

Do not use AC only rated tools with a DC

power supply. While the tool may appear to

work, the electrical components of the AC
rated tool are likely to fail and create a hazard
to the operator.

Keep handles dry, clean and free from oil

and grease. Slippery hands cannot safely

control the power tool.

Use clamps or other practical way to secure
and support the workpiece to a stable

platform. Holding the work by hand or against

your body is unstable and may lead to loss of
control.

Develop a periodic maintenance schedule
for your tool. Wh en cleani ng a tool be
careful not to disassemble any portion of
th e too l since internal wires may be
misplaced or pinched or safety guard return
sp rings may be imprope rly mounted.

Certain cleaning agents such as gasoline,
carbon tetrachloride, ammonia, etc. may
damage plastic parts.

Risk of injury to user. The power cord must only
be serviced by a Dremel Service Facility..

Some dust created by

power sanding, sawing,
grinding, drilling, and other construction
activ ities contains chemicals known to
ca use cancer, b irt h de fec ts or other
reproductive harm. Some examples of
these chemicals are:

• Lead from lead-based paints,

• Crystalline silica from bricks and cement and

other masonry products, and

• Arsenic and chromium from chemically-

treated lumber.

Your risk from these exposures varies,
depending on how often you do this type of
work. To reduce your exposure to these
chemicals: work in a well ventilated area, and
work with approved safety equipment, such as
those dust masks that are specially designed
to filter out microscopic particles.

Additional Safety Warnings

under the workpiece near the line of cut and
near the edge of the workpiece on both sides of
the wheel.

Use extra caution when making a ′′pocket
cut′′ into existing walls or other blind areas.

The protruding wheel may cut gas or water
pipes, electrical wiring or objects that can cause
kickback.

Safety warnings specific for wire

brushing operations:

Be aware that wire bristles are thrown by
the brush even during ordinary operation.
Do not overstress the wires by applying

excessive load to the brush. The wire bristles

can easily penetrate light clothing and/or skin.

Allow brushes to run at operating speed for
at least one minute before using them.
During this time no one is to stand in front

or in line with the brush. Loose bristles or

wires will be discharged during the run-in time.

Direct the discharge of the spinning wire

brush away from you. Small particles and tiny

wire fragments may be discharged at high
velocity during the use of these brushes and
may become imbedded in your skin.

Operating Instructions

The Rotary Tool is a handful of high-speed
power. It serves as a carver, grinder, polisher,
sander, cutter, power brush, drill and more.

The Rotary Tool has a small, powerful electric
universal motor, is comfort able in the hand,
and is made to accept a large variety of
accessories including abrasive wheels, drill
bits, wire brushes, polishers, engraving cutters,
router bits, cutting wheels and attachments.
Accessories come in a variety of shapes and
permit you to do a number of different jobs. As
you be come familiar with the range of
accessories and their uses, you will learn just
how versatile the Rotary Tool is. You’ll see
dozens of uses you hadn’t thought of before.

The real secret of the Rotary Tool is its speed.
To understand the advantages of its high
speed, you have to know that the standard
portable electric drill runs at speeds up to
2,800 revolutions per minute. The Rotary Tool
operates at speeds up to 35,000 revolutions
per minute. The typical electric drill is a low­speed, high torque tool; the Rotary Tool is just
the opposite – a high-speed, low torque tool.
The major difference to the user is that in the
high speed tools, the speed combined with the
acces sory mounted in the collet does the work.
You don’t apply pressure to the tool, but simply
hold and guide it. In the low speed tools, you
not only guide the tool, but also apply pressure
to it, as you do, for example, when drilling a hole.

Sharpen Tools Drilling

Shape Wood Carve Wood

Deburr Metal Cut Metal

BALANCING ACCESSORIES — For precision

work, it is important that all accessories be in
good balance (much the same as the tires on
your automobile). To true up or balance an
accessory, slightly loosen collet nut and give the
accessory or collet a 1/4 turn. Re tighten collet
nut and run the Rotary Tool. You should be able
to tell by the sound and feel if your accessory is
running in balance. Continue adjusting in this
fashion until best balance is achieved. To
maintain balance on abrasive wheel points,
before each use, with the wheel point secured in
the collet, turn on the Rotary Tool and run the
415 Dressing Stone lightly against the revolving
wheel point. This removes high spots and trues
up the wheel point for good balance.

The hanger is provided for the use of hanging
your tool while using the flex-shaft or for

storage. If you do not use the hanger, remove it
from the tool and snap it back into place
underneath the cord so it will be out of the way
while the tool is in use.

FIXING STUCK COLLETS – It is possible for a
collet to get stuck within the collet nut especially if
a collet nut is tightened onto the tool without a bit
in place. If this happens, the collet can be
removed from the collet nut by pushing the shank
of an accessory into the hole in the collet nut.
This should cause the collet to pop out of the
collet nut.

It is this high speed, along with its compact

Always hold the tool
away from your face.
Accessories can be
damaged during
handling, and can fly
apart as they come up
to speed. This is not

common, but it does happen.

Whenever you hold the

tool, be c arefu l not to
cover the air vents with your hand. This
blocks the air flow and causes the motor to
overheat.

For best control in close work, grip the Rotary
Tool like a pencil between your thumb and
forefinger (Figure A).

The “Golf Grip” method of holding the tool is
used for more aggressive operations such as
grinding a flat surface or using cutoff wheels
(Figure B).

Practice on scrap materials first to see how the
Rotary Tool's high speed action performs.
Keep in mind that the work is done by the
speed of the tool and by the accessory in the
collet. You should not lean on or push the tool
during use.

Instead, lower the spinning accessory lightly to
the work and allow it to touch the point at
which you want cutting (or sanding or etching,
etc.) to begin. Con centrate on guiding the tool
over the work using very little pressure from
your hand. Allow the accessory to do the work.

Usually, it is best to make a series of passes
with the tool rather than attempt to do all the
work in one pass. To make a cut, for example,
pass the tool back and forth over the work,
much as you would a small paint brush. Cut a
little material on each pass until you reach the
desired depth. For most work, the gentle touch
is best. With it, you have the best control, are
less likely to make errors, and will get the most
effi cient work out of the accessory.

size and wide variety of special accessories
and attachments, that makes the Rotary Tool
differ ent from other tools. The speed enables it
to do jobs low speed tools cannot do, such as
cutting hardenedsteel,engraving glass,etc.

Getting the most out of your Rotary Tool is a
matter of learning how to let this speed

work for you.

Using the Rotary Tool

The first step in learning to use the Rotary
Tool is to get the “feel” of it. Hold it in your
hand and feel its weight and balance.

Operating Speeds

To select the right speed for each job, use a
practice piece of material.

NO TE: Spe ed is aff ect ed b y voltage
changes. A reduced incoming voltage will
slow the RPM of the tool.

(MODEL 100)

On the single speed model, there is an ON­OFF switch. When the switch is on, the tool
runs at 35,000 RPM.

(MODEL 200)

On the two-speed model, there is a LO and HI
switch. When the switch indicator is on the low
setting, the tool runs at about 15,000 RPM.
When the switch indicator is on the high
setting, the tool runs at about 35,000 RPM.

(MODEL 3000)

On the vari able speed model, there are
switch setting in dicators marked with a line.
Slide to the number on the housing to select
the operating speed needed from 5,000 –
35,000 RPM.

You can refer to the charts on page 24, 25,
26 and 27 to determine the proper speed,
based on the material being worked and the
type of accessory being used. These charts
enable you to select both the correct acces ­sory and the optimum speed at a glance.

The speed of Rotary Tool is controlled by
setting this indicator on the housing.

Needs for Slower Speeds

Certain materials, however, (some plastics and
precious metals, for ex ample) require a
relatively slow speed because at high speed
the friction of the accessory generates heat
and may cause damage to the material.

Slow speeds (15,000 RPM or less) usually are
best for polishing operations employing the felt
polishing ac ces sories. They may also be best
for working on deli cate projects as “eggery”
work, delicate wood carving and fragile model
parts. All brushing applications require

lower speeds to avoid wire discharge from
the holder.

No t fo r us e wi th two

speed or variable speed
models 200 or 3000. Use with e xternal
speed control will damage the variable/two
speed electronics.

Higher speeds are better for carving, cutting,
routing, shaping, cutting dadoes or rabbets in
wood.

Hardwoods, metals and glass require high
speed operation, and drilling should also be
done at high speeds.

You can do the great majority of work with the
single speed at its regular speed of 35,000
RPM. But for certain materials and types of
work, you need slower speeds — which is the
reason the variable speed models are
available.

To aid you in determining the optimum
operational speed for differ ent materials and
different accessories, we have constructed a
series of tables that appear on page 24, 25, 26
and 27. By referring to these tables, you can
discover the recommended speeds for each
type of accessory. Look these tables over and
become familiar with them.

Ultimately, the best way to determine the
correct speed for work on any material is to
practice for a few minutes on a piece of scrap,
even after referring to the chart. You can
quickly learn that a slower or faster speed is
more effective just by observing what hap pens
as you make a pass or two at different speeds.
When working with plastic, for example, start at
a slow rate of speed and increase the speed
until you observe that the plastic is melting at
the point of contact. Then reduce the speed
slight ly to get the optimum working speed.

Maintenance Information

Some rules of thumb in regard to speed:

1. Plastic and other materials that melt at low
temperatures should be cut at low speeds.

2. Polishing, buffing and cleaning with any
type of bristle brush must be done at
speeds not greater than 15,000 RPM to
prevent damage to the brush from bristles
flying toward operator.

3. Wood should be cut at high speed.

4. Iron or steel should be cut at high speed. If
a high speed steel cutter starts to chatter —
this normally means it is running too slow.

5. Aluminum, copper alloys, lead alloys, zinc

alloys and tin may be cut at various speeds,
depending on the type of cutting being
done. Use paraffin or other suitable
lubricant on the cutter to prevent the cut
material from adhering to the cutter teeth.

Increasing the pressure on the tool is not the
answer when it is not performing as you think it
should. Perhaps you should be using a
different accessory, and perhaps an
adjustment in speed would solve the problem.
Leaning on the tool does not help.

Let speed do the work!

Use only Dremel®, high-performance accessories.

Service

Preventive maintenance

pe r fo rme d by
unautho rized per so n nel ma y re sult in
mi spl aci ng of inte rna l wir es and
components which could cause serious

hazard. We recommend that all tool service be

performed by a Dremel Service Facility.

To avo id inju ry fro m

unexpected starting or
electrical shock, always remove plug from
wall outlet before performing service or
cleaning.

CARBON BRUSHES

The brushes and commutator in your tool have
been engineered for many hours of
dependable service.

In order to prepare your brushes for use, run
your tool at full speed for 5 minutes under no
load. This will properly “seat” your brushes,
which extends the life of both your brushes
and your tool.

To maintain peak efficiency of the motor, we
recommend every 40 - 50 hours the brush es
be examined. Only genuine Dremel replace ­ment brushes specially designed for your tool
should be used.

MAINTENANCE OF REPLACEABLE

BRUSHES ON MODELS 100, 200 & 3000

The brushes should be inspected frequently
when tools are used continuously. If your tool
runs spo rad ically, loses power, makes unusual
noises or runs at a reduced speed, check the
brushes.

To c ontin ue u sing the
tool in this condition will

permanently damage your tool.

Follow these steps to check/change the rotary
tool brushes:

1. With the power cord unplugged, place the
tool on a clean surface. Use the tool
wrench as a screwdriver to remove the
brush caps in a counter-clockwise direction
(Figure C).

FIG. C

2. Remove the brushes from the tool by
pulling on the spring that is attached to the
carbon brush. If the brush is less than 1/8"
long and the end surface of the brush that
contacts the commutator is rough and/or
pitted, they should be replaced. Check both
brushes (Figure D).

Usually the brushes will not wear out simul ­taneously. If one brush is worn out, replace
both brushes. Make sure the brushes are
installed as illus trated. The curved surface
of the brush must match the curvature of
the commutator.

3. After replacing brushes the tool should be
run at no-load; place it on a clean surface
and run it freely at full speed for 5 minutes
before loading (or using) the tool. This will
allow the brushes to “seat” properly and will
give you more hours of life from each set of
brushes. This will also extend the total life of
your tool since the com mutator surface will
“wear” longer.

BEARINGS

Models 100, 200, and 3000 have double ball
bearing construction. Under normal use they
will not require lubrication.

Cleaning

To a void acc ide nts
always dis connect the

tool from the power supply before cleaning

or performing any main tenance. The tool

may be cleaned most effectively with
compressed dry air. Always wear safety gog -

gles when cleaning tools with compressed
air.

Ventilation openings and switch levers must be
kept clean and free of foreign matter. Do not
at tempt to clean by inserting pointed objects
through openings.

Certain cleaning agents
an d sol v ent s damage

plastic parts. Some of these are: gasoline,

carbon tetrachlo ride, chlo rinated cleaning
solvents, ammonia and house hold detergents
that contain ammonia.

Extension Cords

If an extension cord is

necessary, a cord with
adequate size conductors that is capable
of carrying the current necessary for your

to ol mu st be used . This will prevent

excessive voltage drop, loss of power or
overheating. Grounded tools must use 3-wire
extension cords that have 3-prong plugs and
receptacles.

COLLETS

If you expect to use a variety of accessories,
we recommend that in the beginning you
purchase a complete set of four collets. Store
these so that you will have the proper size of
collet for any accessory or drill bit you want
to use. Currently, the 1/8", 3/32",1/32" and

1/16" collets accommodate all of the avail ­able Dremel accessories. 1/8" collets are
included in most rotary tool kits.

MANDRELS

A mandrel is a shank with a threaded or screw
head, which are required when you use
polishing accessories, cutting wheels, sanding
discs, and pol ish ing points. The reason
mandrels are used is that sanding discs,
cutting wheels and similar accesso ries must
be replaced frequently. The mandrel is a per ­manent shank, allowing you to replace only
the worn head when necessary, thus saving
the expense of replacing the shaft each time.

Screw Mandrel No 401

This is a screw mandrel used with the felt
polishing tip and felt polishing wheels. 1/8"
shank.

Small Screw Mandrel No 402

This is a mandrel with a small screw at its tip,
and is used with emery and fiberglass cutting
wheels, sanding discs and polishing wheels.
1/8" shank.

EZ Lock Mandrel No 402

Engraving Cutters

This group has a wide variety of sizes and
shapes, and are made for intricate work on
ceramics (greenware), wood carvings,
jewelry and scrimshaw. They often are used
in making complicat ed printed circuit boards.
They should not be used on steel and other
very hard materials but are excellent on
wood, plastic and soft metals. 1/8" shank.

Structured Tooth

Tungsten Carbide Cutters

Fast cutting, needle-sharp teeth for greater
material removal with minimum loading. Use
on fiberglass, wood, plastic, epoxy and
rubber. 1/8" shank.

Aluminum Oxide Grinding Stones

(red/brown)

Round, pointed, flat — you name the shape
and there is one available in this category.
These are made of aluminum oxide and
cover virtually every possible kind of grinding
application. Use them for sharpening lawn
mower blades, screwdriver tips, knives,
scissors, chisels and other cutting tools. Use
to remove flash from metal castings,
deburring any metal after cutting, smoothing
welded joints, grinding off rivets and re mov ing
rust. These grinding stones can be resharped
with a dressing stone. In machine shops, high
speed drills and cut ters normally are ground
with aluminum oxide wheels. 1/8" shank.

Silicon Carbide Grinding Stones

(blue/green)

Tougher than aluminum oxide points, these
are made es pecially for use on hard
materials such as glass and ce ramics.
Typical uses might be the removal of stilt
marks and excess glaze on ceramics and
engraving on glass. 1/8" shank.

Diamond Wheel Points

Excellent for fine detail work on wood, jade,
ceramic, glass and other hard material. Bits
are covered with diamond particles. 1/8"
shanks. (Not recommended for drilling)

Wire Brushes

Three different shapes of wire brushes are
available. For best results wire brushes

should be used at speeds not greater than
15,000 RPM. Refer to Operating Speeds

section for proper tool speed setting. The

three shapes come in three different
materials: stainless steel, brass and carbon
wire. The stainless steel perform well on
pewter, aluminum, stainless steel, and other
metals, without leaving "after-rust". Brass
brushes are non sparking, and softer than
steel; making them good for use on soft
metal like gold, cooper and brass. The
carbon wire brushes are good for general
purpose cleaning.

Bristle Brushes

These are excellent cleaning tools on
silverware, jew elry and antiques. The three
shapes make it possible to get into tight
corners and other difficult places. Bristle
brushes can be used with polishing
compound for faster cleaning or polishing.

Brushing Pressure

1. Remember, the tips of a wire brush do the
work. Operate the brush with the lightest
pressure so only the tips of the wire come
in contact with the work.

2. If heavier pressures are used, the wires
will be overstressed, resulting in a wiping
action; and if this is continued, the life of
the brush will be shortened due to wire
fatigue.

3. Apply the brush to the work in such a way
that as much of the brush face as possible
is in full contact with the work. Applying the
side or edge of the brush to the work will
result in wire breakage and shortened
brush life.

Polishing Accessories

These include an impregnated polishing
point and an impregnated polishing wheel for
bringing metal sur faces to smooth finish; a
felt polishing tip and felt polish ing wheel, and
cloth polishing wheel, all used for polishing
plastics, metals, jewelry and small parts. Also
included in this group is a polishing
compound (No. 421) for use with the felt and
cloth polishers.
Polishing points make a very smooth
surface, but a high luster is obtained using
felt or cloth wheels and polishing compound.

For best results polishing accessories
should be used at speeds not greater than
15,000 RPM.

No polishing compound is needed when
using the 425 Polishing Wheel.

Aluminum Oxide Abrasive Wheels

Use to remove paint, deburr metal, polish
stainless steel and other metals. Available in
medium grit. 1/8" shank.

Sanding Accessories

Sanding discs in fine, medium and coarse
grades are made to fit mandrel 402 and
EZ402. They can be used for nearly any
small sanding job you might have, from
model making to fine furniture finish ing. In
addition, sanding bands are made to fit
sanding drum mandrels 407 and EZ407SA,

and they make it possible to shape wood,
smooth fiberglass, sand inside curves and
other difficult places, and perform other
sanding jobs. Sanding bands should be
replaced on the drum as they become worn
and lose their grit. Bands come in fine
medium and coarse grades. Flapwheels
grind and polish flat or contoured surfaces.
They are used most effectively as a finishing
sander after heavier surface sanding and
material removal is completed. Flapwheels
come in fine and coarse grades. Abrasive
Buffs are a great finishing accessory for
cleaning and light sanding. They work
effectively on metal, glass, wood, aluminum
and plastics.

Grinding Wheel

Use for deburring, removing rust, and general
purpose grinding. Use with Mandrel #402.

Cutting Wheels

These thin discs of emery or fiberglass are
used for slicing, cutting off and similar
operations. Use them for cutting off frozen
bolt heads and nuts, or to reslot a screw
head which has become so damaged that
the screwdriver won’t work in it. Fine for
cutting BX cable, small rods, tubing, cable
and cutting rectangular holes in sheet metal.

Mandrel N° 402 has a small screw at its tip,
and is used with emery cutting wheels and
sanding discs. Higher speeds, usually

maximum, are best for most work, including
cutting steel. Which is shown here.

Man d r el N o . 401 is used with the felt
polishing tip and wheels. Thread the tip on to
the screw carefully. The felt tip must thread

down straight on the screw Mandrel, and be
turned all the way to the collar.

To replace a band on the Drum Sander, loosen
the screw without removing it to contract the
drum then slide the old band off. Slide the new
sanding band on and then expand the drum by
tightening the screw once again.

Before each use, check

to make certain that all
components are assembled to accessory
shank and that the drum is sufficiently

expanded to secure the band during use. If

sanding band is loose on the drum during
operation it may “fly” off and strike you or
bystanders.
