General Power Tool Safety Warnings

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.

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.

2

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

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 osition before
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 Rules for Rotary Tools

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 operating
speed setting marked on the power tool.

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 tool.

Safety Rules for Rotary Tools - (cont.)

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.

Safety Rules for Rotary Tools - (cont.)

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 edges e tc. Av oid bouncing 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 mater ial (whic h i s the s ame

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

clampe d. 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 rec omm ended ap plica tions. F or
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
unreli ev ed shoul der flan ge that are o f

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 wh ee l 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
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.

Safety Rules for Rotary Tools - (cont.)

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.

Additional Safety Warnings

Do not use rou ter bit

with the Dremel chuck.

Bit may become a projectile and cause serious
injury.

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. When cleaning a tool be
careful not to disassemble any portion of
th e too l sin ce in terna l wir es ma y be
misplaced or pinched or safety guard return

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.

sp rings may be imp roperly mounte d.

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
activities contains chemicals known to
ca use can cer, b irt h defec ts or oth er
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.

DREMEL CHUCK

Dremel Chuck allows you to quickly and
easily change accessories on Dremel Rotary
Tools without changing collets. Accepts
accessories with 1/32” - 1/8” shank. To
loosen, first press shaft lock button and
rotate the shaft by hand until the lock
engages the shaft preventing further rotation.

Do not enga g e l o c k

while the Rotary Tool is

running.

With the shaft lock engaged use the wrench
or the EZ Twist Nose Cap to loosen the
chuck and open the jaws. Remove the
accessory from the chuck. If necessary,
continue loosening the chuck so that the new
accessory fits between the jaws. Insert the
new accessory into the chuck far enough so
that there is approximately 1/4” between the
end of the chuck and the beginning of the
working part of the accessory (drill bit flutes,
sand paper, engraving end, etc.). With the
shaft lock engaged, tighten the chuck using
the EZ Twist Nose Cap or wrench to secure
the accessory.

Helpful Tips when using the

Dremel Chuck

• The Dremel Chuck and the collet and collet
nut system are interchangeable on this tool.
While the chuck will provide you with the best
experience for changing accessories, the
collet and collet nut will provide a more
precise accessory holding solution especially
in heavier side load applications. If you will be
using your rotary tool for routing, heavy wood
or metal cutting, heavy sanding, or carving
you will probably have a better experience
using the collet and collet nut.

• The Dremel Chuck needs to be securely
tightened in order to retain the accessory
during use. If you find the accessory slipping
in the chuck, use the included EZTwist Nose
Cap or wrench to tighten the chuck around
the bit. If further slippage persists, switch to
using the collet and collet nut.

• The jaws of the chuck can become displaced
if dropped, pried against, or filled with dust
causing the accessory to no longer run true
and concentric. This is often called run-out.
To reset the jaws, apply the following
procedure:

1. Remove the accessory from the chuck.

2. Clean the chuck if necessary using

compressed air.

3. Press shaft lock button and tighten the chuck
until the jaws extend past the outer surface of
the chuck, approximately 1/8".

4. Push the end of the chuck firmly against a
hard flat surface to be sure the jaws are all
seated axially.

5. Continue to hand tighten the chuck until the
jaws completely close.

6. Loosen the chuck, and reinsert a straight
accessory.

7. Turn the tool by hand and observe if there is
any run-out. If there is obvious run-out,
repeat the procedure.

8. With the shaft lock engaged, tighten the
chuck using the EZ Twist Nose Cap or
wrench to secure the accessory.

9. Turn the tool on to the lowest speed setting
and observe for run-out. If there is obvious
run-out, check that the accessory is straight
before repeating the procedure.

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
chuck or collet nut and give the accessory or
collet a 1/4 turn. Re tighten the chuck or 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.

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.

Dremel 4300 is equipped with a quick shaft lock
mechanism. This mechanism engages the
output shaft in 8 separate locations on the shaft
for easier operation.

Do not engage lock while
the Rotary Tool is running.

With the shaft lock engaged use the collet
wrench to loosen the collet nut if necessary. The
collet nut must be loosely threaded on when
inserting an accessory. Change accessories by
inserting the new one into the collet as far as
possible to minimize runout and unbalance.
With the shaft lock engaged, use collet wrench
or EZ Twist Nose Cap to securely tighten the
collet nut. (Fig. 5). Avoid excessive tightening

of the collet nut whe n the re is no bit
inserted.

Operating Instructions

Thank you for purchasing the Dremel 4300.

Dremel 4300

This product was designed by the many
Dremel users who passionately use their rotary
tools daily. This tool was designed to give you
the ultimate performance when working on
projects.

The Dremel 4300 is the MOST versatile rotary
tool available today. It has a wide speed range
including a high performance motor with
electronic feedback that allows the tool to
maintain its speed under load. The design of
the tool is symmetrical and contains plenty of
soft grip so the tool can be held comfortably in
many positions. The inclusion of the Dremel
Chuck allows you to use any shank size
accessory from 1/32” to 1/8” so that you don’t
have to change collets when you change to a
different size accessory. In addition, the
included worklight will help you see every detail
as you work on your project. You will appreciate
the many applications that the Dremel 4300
can easily tackle.

Rotary Tool Introduction

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, polishing accessories, 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 chuck or 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.

14

It is this high speed, along with its compact 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
hardened steel, en graving glass, etc.

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

for you.

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. Feel
the taper of the housing. This taper permits

common, but it does happen.

cover the air vents with your hand. This
blocks the air flow and causes the motor to
overheat.

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.

For best control in close or detailed work, grip
the Rotary Tool like a pencil between your
thumb and forefinger (Fig. 7).

The “Golf Grip” method of holding the tool is
used for more aggressive operations such as
grinding a flat surface or using cutoff wheels
(Fig. 8).

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.

storage. If you do not use the hanger, snap it
back into place so it will be out of the way while
the tool is in use (Fig. 1).

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.

SLIDE "ON/OFF" SWITCH

The tool is switched "ON" by the slide switch
located on the topside of the motor housing.

TO TURN THE TOOL "ON", slide the switch
button forward.

TO TURN THE TOOL "OFF", slide the switch
button backward.

HIGH PERFORMANCE MOTOR

Your tool is equipped with a high performance
rotary tool motor. This motor expands the
versatility of the rotary tool by driving additional
attachments such as the Dremel Right Angle
Attachment and Dremel Flex Shaft.

ELECTRONIC FEEDBACK

Your tool is equipped with an internal electronic
feedback system that provides a “soft start”,
which will reduce the stresses that occur from
a high torque start. The system also helps to
keep the preselected speed virtually constant
between no-load and load conditions.

VARIABLE SPEED DIAL

Your tool is equipped with a variable speed
dial. The speed may be adjusted during
operation by presetting the dial on or
between any one of the settings.

You can refer to the charts on pages 27–30
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 dial on the housing (Fig. 9).

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.)

Needs for Slower Speeds

www.GlobalTestSupply.com

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.

The point to remember is this: Many
applications and accessories in our line will
provide the best performance at full speed, but
for certain materials, applications, and
accessories, you need slower speeds, which is
the reason our 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 pages 27–30.
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.

Some rules of thumb in regard to speed:

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

Use only Dremel®, high-performance accessories.

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.

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!

Maintenance Information

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

Service

Preventive maintenance

pe r form e d by
unau thorize d per so n nel m ay resu lt in
mis p l acin g of i n t erna l wire s and
components which could cause serious

hazard. We recommend that all tool service

be performed by a Dremel Service Facility.

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 MODEL 4300

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 ontinue using the

too l i n t h is c ondi t ion

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 (Fig. 10).

17

Find Quality Products Online at: [e-mail]

www.GlobalTestSupply.com

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 (Fig. 11).

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. Also check that the brush caps
sit flush with the tool housing.

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

Model 4300 has ball bearing construction.
Under normal use no additional lubrication is
required.

, high-performance accessories. Other accessories are

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

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)

section for proper tool speed setting.
Three different shapes of wire brushes are

available. 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, copper 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.

INCORRECT:

Excessive pressure can cause wire breakage.

CORRECT: Wire tips doing the work.

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.

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.

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 bands in fine, medium and coarse
grades are made to fit mandrel No. 402 and
EZ407. They can be used for nearly any
small sanding job you might have, from
model making to fine furniture finish ing. In
addition, there is the drum sander, a tiny
drum which fits into the Rotary Tool and

cult places, and other sanding jobs. You
replace the sanding bands 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.
Buffs are a great finishing accessory for
cleaning and light sanding. They work
effectively on metal, glass, wood, aluminum
and plastics. Coarse and medium buffs are

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

EZ Drum™Operating Instructions

EZ Drum™ Mandrel No. EZ407SA has a

spring loaded sleeve and is used with
sanding bands.

Always make sure the

rotary tool is “OFF” and
dis c o nnec t the p l ug f r o m t h e powe r
source or the battery pack from the tool

bef o r e cha n ging a c cesso r i es. Such

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

Always make sure accessory is properly

seated on mandrel before use. Incorrect

seating of accessory on mandrel may lead to
personal injury or property damage.

To load accessory:

1. As indicated, place two fingers underneath

the mandrel and pull firmly up. This will
place the EZ Drum™ in the "unlocked"
position (Fig. 1).

2. Keeping two fingers beneath the mandrel,

slide the sanding band down until the
entire blue mandrel is covered (Fig. 2).

3. To return to "locked" position, press firmly

down on the top of the mandrel (Fig. 3).

Removing the sanding band on

the mandrel:

1. Place two fingers underneath the mandrel

and pull firmly up. This will place the EZ
Drum™ in the "unlocked" position (Fig. 1).

2. Sanding band will now easily slide off

mandrel (Fig. 2). Do not squeeze sanding
band when removing from EZ Drum™
mandrel. This can lead to rubber band
pulling off mandrel and becoming
inoperable.

Safety Rules for Flex Shaft

Re ad the too l m anu al

for the use of this accessory with your tool.

Failure to follow all instructions listed below
may result in serious personal injury.

Wear ANSI compliant eye protection. The
operation of any powe r tool can result in
foreign objects being thrown into the eyes.

Do not operate the
flexible shaft with a
sharp or multiple
bends. Ensure that
there are no sharp
residual bends or
kinks in the flexible
shaft before operation. Over bending the

shaft can generate excessive heat on the
jacket or h and pi ec e and may caus e the
flexible shaft to disengage from tool. The
minimum recommended bend radius is 6”.

Always hold the hand piece firmly in your
hands during the start-up. The reaction

and these instructions

6" RADIUS

torque of the motor, as it accelerates to full
speed, can cause the shaft to twist.

No t for use wit h r o uter bit s o r oth er
large diameter (1” or larger) bits. Large

diameter bits can cause kickback and loss
of control when used with the flexible shaft.

Do not remove end ferrule while tool is
running. The cable will become loose from the

jacket and will uncontrollably whip or lash
around.

Installation Instructions

It is extremely important to carefully read and
follow the directions to assemble the flexible
shaft to your rotary tool below to ensure the
tool will function properly.

To pro perly a ttach t he Flex S haft to th e
rotary tool, THREE items must be removed

driver cap. Tighten the driver cap finger tight

and then tighten an additional 1/3 turn with the
wrench or nose cap. (Wrench included with
your rotary tool kit)

5. Attach by screwing the collar of the Flex

Shaft 7 to the rotary tool. Make sure the
square end of the center core engages the
sq uar e hol e socket in th e driv e r ca p
(Fig. A5).

6. Refer to “Dremel Chuck” and “Collets”
se ction s of th e rotar y tool manua l for
instructions on how to change accessories.

Do no t pull out center

co re to e nga ge in to

driver cap. This could cause disengagement

of center core from handpiece. If tool stops
when shaft is bent, center core may be lodged
in driver cap. Loosen shaft and remove core
from driver cap. Then screw flexible shaft onto
rotary tool housing again.

Operating Instructions

Run-In before Operation

For optimum performance, allow your new flex
shaft attachment to run at high speed on your
rotary tool in a vertical position for 2 minutes
before use (Fig. A7).

Disengagement of the Flex Shaft

The flexible shaft may become disengaged if
the motor of your rotary tool is not elevated
higher than the working end of the Flex Shaft.

Collet Removal and Replacement

Four different size collets to accommodate
different shank sizes, are sold separately for
your Flex Shaft. To install a different collet,
remove the collet nut 2 and remove the old
collet 4. Insert the unslotted end of the collet in
the hole in the end of the Flex Shaft 8. Replace
collet nut on the shaft (Fig. A5).

Flexible Shaft Lubrication

The Flex Shaft should be lubricated after every
25-30 hours of use. To lubricate, unscrew the
Flex Shaft assembly from the motor housing.
Pull the center core out of the Flex Shaft
assembly. Wipe a very thin film automotive
wheel bearing grease on to the center core and
reinsert it back into the shaft. To prevent

damage to tool do not over grease shaft.

To o m uch gr ease will ca use th e u nit to
overheat.

Reattach the Flex Shaft to the rotary tool.

Drywall Cutting Bit – For use in drywall.

Use with 1/8" (3.2 mm) collet #480 and collet
nut.

When inserting the #560 bit into your rotary
tool, it is very important that at least 1/16” (1.6
mm) and no more than 1/8" (3.2 mm) of
smooth shank remains visible above the collet.
Leaving too much shank out of the tool can
cause the bit to spin unevenly and make the
tool difficult to control. The guide has a "0"
depth marking on it, however, when inserted
properly, the bit will stick out from the end of
the guide by 1/16” (1.6 mm) – 1/8" (3.2 mm).
The depth can be adjusted from that point on a
continuous slide up to 3/4" (19 mm).

When making freehand cuts in drywall – e. g.
Repairing a hole in drywall, you may use the
#560 Drywall Cutting Bit (cutting in a counter
clockwise direction) or the #561 Multipurpose
Cutting Bit (cutting in a clockwise direction).

When using a template (like an outlet box)
behind the drywall, use the drywall bit #560,
cutting in a counter clockwise direction. When
