Work area safety
Keep w o r k area c l e a n and w e l l 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
use an y a d a p t e r plugs with earthed
(grounded) power tools. Unmodified plugs
and matching outlets will reduce risk of
electric shock.
Avoid body contact wi t h 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 da m p
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
use c ommon sense w h e n operating 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 p r o t e c t i v e 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.
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

Prevent unintentional starting. Ensure the
switch is in the o f f - p o s i t i o n b e f o r e
conn e c t i n g to p o w e r source a n d / o r
battery pack, picking up or carrying the
tool. Carrying power tools with your finger
on the switch or energizing power tools that
have the switch on invites accidents.
Remo v e any a djusting ke y or w r e nch
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 not forc e the powe r tool . Use the
correct power tool for your application.
The correct power tool w ill 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
adjustme nts, 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 an d do not allow pe r s o n s
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.
Proper ly m aintained cut ting tools with
sharp cutting edges are less likely to bind
and are easier to control.
Use the power tool, accessories and tool
bits et c . i n accordance with these
instr u c t i o n s , taking i n t o account t he
working conditions and the work to be
perf o r m e d . U s e of t h e power t o ol for
operations different from those intended
could result in a hazardous situation.
Battery tool use and care
Recharge only with the charger specified
by the manufacturer. A charger that is
suitable for one type of battery pack may
create a risk of fire when used with another
battery pack.
Use power tools only with specifically
designated battery packs. Use of any other
battery packs may create a risk of injury and
fire.
When battery pack is not in use, keep it
away from other metal objects like paper
clips, coins, keys, nails, screws, or other
small metal ob j e c t s that can make a
connection from one terminal to another.
Shorting the battery terminals together may
cause burns or a fire.
Under abusive conditions, liquid may be
ejected from the battery, avoid contact. If
contact accidentally occurs, flush with
water. If liquid contacts eyes, additionally
seek medical help. Liquid ejected from the
battery may cause irritation or burns.
Service
Have your po w e r tool serviced by a
qualified repair person using only identical
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 grinder, sander, wire brush, polisher,
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 us e access ories 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 RATED SPEED of the accessories must
be at least equal to the operating speed
setting ma r k e d on the power to o l .
Accessories running faster than their RATED
SPEED can break and fly apart.
The outside diameter and the thickness of
your accessory mu s t be wi t h i n the
capacity rating o f your p o w e r tool.
Incorrectly sized accessories cannot be
adequately controlled.
The arbor size of wheels, sanding drums or
any other accessory must properly fit the
spindle or collet of the po w e r tool.
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 collet or chuck. If the
mandrel is insufficiently held and/or the
ov erhan g of the wheel i s to o lo ng, 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 cr acks ,
sanding drum for cracks, tear or excess
wear, wire brush for loose o r cracked
wires. If power to o l or accessory is
dropped, inspect for damage or install an
undamaged accessory. After inspecting
and i nstalling an a c c e s s o r y , position
yourself and bystanders away from the
plane of the rotating accessory and run the
power tool at maximum no-load speed for
on e mi nute. D amage d accessor ies will
normally break apart during this test time.
We a r per s onal p r otective equip ment.
Depending on application, use face shield,
safety goggles or sa f e t y glasses. As
ap propr iate, wea r du st mask, heari ng
protectors, gloves and workshop apron
capabl e of st opping small abrasive or
workpiece fragments. The eye protection
must be capable of stopping flying debris
generated by various operations. The dust
mask o r respirator must be ca pable of
filtrating particles generated by yo u r
operation. Prolonged exposur e 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 power tool by insulated gripping
surfaces on l y , w h e n p e r f o r m i n g a n
operation where the cutting accessory may
contact hidden wiring. 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
se c urely t ightened . L oose a d justment
devices can unexpectedly shift, causing loss
of control, loose rotating components will
be violently thrown.
Safety Rules for Rotary Tools

Safety Rules for Rotary Tools
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 not op e r a t e the power to o l near
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 for 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 th e
rotating accessory which in turn causes the
uncontrolled power tool to be forced in the
direction opposite of the accessory’s
rotation.
For ex a m p l e , if an ab r a s i v e 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 k i c k b a c k forces, if proper
precautions are taken.
Use special care when working corners,
sha r p edges etc. Avoid bo u ncing an d
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
sa me directio n as the cut ting edge is
exiting from the material (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
clamped. 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 cuttingoff operations:
Use only wheel types that a r e
recommended for your power tool and
only for recommended applications. 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
unrelieved shoulder flange 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 c u t .

Safety Rules for Rotary Tools
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 wheel 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 a n y o v e r s i z e d
workpiece to minimize the risk of wheel
pinching and kickback. Large workpieces
tend to sag under th e i r own weight.
Supports m u s t be p l a c e d under t h e
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
excessi ve l oad to the brush. T he 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.

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.
Develop a periodic maintenance schedule
for your tool. When cleaning a tool be
careful not to disassemble any portion of
the to o l since internal wires may be
mi splaced or pin ched or safety gua rd
return s p r i n g s may be i m p r o p e r l y
mounted. Certain cleaning agents such as
gasoline, carbon tetrachloride, ammonia,
etc. may damage plastic parts.
Some d ust creat ed by
power sanding, sawing,
grinding, drilling, and other construction
activities contains chemicals known to
cause cancer, birth defects 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.
Yo ur r isk from these exp osure s va ries,
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.

Collet Nut
To loosen the collet nut, first press shaft
lock button and rotate the shaft by hand
until th e l o c k e n g a g e s the shaft
preventing further rotation. Your Dremel
Lite 7760 is equipped with a shaft lock
mechanism. This mechanism engages
the output shaft in 4 separate locations
on the shaft for easier operation.
Do not engage lock
while the Rotary Tool
is running.
With the shaft lock 7 engaged, use the
EZ TWIST™ integrated wrench / nose cap
3 (or collet wrench 15) to loosen the
collet nut 1. 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 7 engaged, tighten the
collet nut 1 securely with EZ TWIST™
integrated wrench/nose cap 3 or collet
wrench 15 (Fig. 2). Avoid excessive
tightening of the collet nut when there
is no bit inserted.
Collets
Four d i f f e r e n t size c o l l e t s , to
accommodate different shank sizes, are
avail able for your Rotary Tool. Collet
sizes can be identified by the rings on
the back end of collet. 1/8" Collet has
no rings and is included in most tool
kits.
To install a different collet, remove the
collet nut and remove the old collet.
Insert the unslotted end of the collet in
the hole in the end of the tool shaft.
Replace collet nut on the shaft.
Always use the collet
wh ich matches the
shank size of the accessory you plan to
use. Never force a larger diameter shank
into a collet.
Note: M o s t rotary tool kits d o not
include all four collets sizes.
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.
Assembly
Always be sure the tool is turned “OFF” before changing accessories,
changing collets or servicing your cordless rotary tool.

Rotary Tool Introduction
The Rotary Tool has a small, powerful
electric motor, is comfort able in the
hand, and is made to accept a large
variety of accessories including abrasive
wheels, d r i l l bits, w i r e brushes,
polishers, engraving cutters, cutting
wheels. 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 25,000 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
Introduction
Balancing Accessories
For precision work, it is important that
all accessori e s be i n good b a lance
(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
so und a nd fe el if you r acc essory is
running in balance. Continue adjusting
in this fashion until best balance is
achieved. To m a i n t a i n 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.

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.
It is thi s hi gh s peed, along with its
compact size and wide variety of special
accessories, 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. To learn about more
uses and the versatility of Dremel
accessories and attachments refer to
this Owner's Manual or check our
website at www.Dremel.com.
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 b a l a n c e . Feel t h e taper of t h e
housing.
Alw a y s hold t he
tool aw a y from
your face.
Accessories c a n
be damaged
du ring handli ng,
and can fly apart
as they come up to speed. This is not
common, but it does happen.
Whenever you hold
the tool, be careful
not to cover the air vents with your
ha nd. T his b locks the a ir 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 (Fig. 4).
The “Golf Grip” method of holding the
tool can be used for more aggressive
operations such as grinding a flat
surface or using cutoff wheels (Fig. 5).
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 o r etching, e t c . ) to b e g i n .
Concentrate 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.

Operating Speeds
To select the right speed for each job, use a
practice piece of material.
“On/Off” / Speed Switch
The tool is controlled by the blue
“On/Off” / Speed Switch 8 located on
the topside of the recessed part of the
housing (Fig. 6).
TO TURN THE TOOL “ON” gently slide
the switch 8 up with your thumb. The
tool will start working at a speed of
8,000 RPM.
The speed may b e adjusted d u r i ng
operation by continuing to gently slide
the switch 8 up with your thumb.
Settings for Approximate
Revolutions:
You can refer to the charts on pages
28–31 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
correc t accessory and the optim um
speed at a glance.
Electronic Monitoring
Your tool is equipped with an internal
electronic monitoring system that helps
to maximize m o t o r an d battery
performance by limiting the current to
the tool when overload and stall
conditions occur. If you stall the tool for
too long, or bind the bit in a work piece,
especially at high speeds, the tool will
automatically turn itself off thanks to
th e fal lback bui lt in to it. On ce th is
ha ppens , sl ide speed switch to “0”
position, simply take the tool out of the
material you were stalled in, turn it back
on again, adjust the speed if necessary,
and continue using it. When the battery
is close to empty, the tool may shut
down automatically more frequently
than normal. If this happens, it is time
to recharge the tool.
Needs for Slower Speeds
Certain m a t e r i a l s , however, ( s o m e
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 ( 1 5 ,000 RPM o r less)
usually are best for polishing operations
employing the felt polishing ac ces sories.
They may also be best for working on
de li cate pro jects as “eggery” work,
delicate wood carving and fragile model
parts. All brushing applications require
lower speeds to avoid wire discharge
from the holder.
Higher speeds are better for carving,
cu tting, sha ping, cutting dad oes o r
rabbets in wood.
Hardwoods, metals and glass require
high speed operation, and drilling
should also be done at high speeds.
Many applications and accessories in
our line will provide th e best
performance a t full speed, b u t for
certai n materials, applica tions, 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
an d diffe r ent ac c essories, we have
co n s tructed a s e ries o f table s that
appear on page 28–31. By referring to
these tables, y o u can d i s c o v e r the
recommended speeds for each type of
accessory. Look these tables over and
become familiar with them.

Operating Speeds
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 ra t e of speed an d
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.
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
start s to chatter — thi s 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 o f cutting being d one. 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 w h e n it is n o t
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.
Your Dremel Lite 7760 can be used with
all of the Dremel accessories, except
router bits. While the tool will work with
cut-off wheels, the reduced speed of
this tool will not allow them to perform
optimally. They can be used to cut soft
materials such as wood or plastic, but
cutting metals is not recommended.
Let speed do the work!

Dremel Accessories
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 t o use. Currently, t h e 1/8",
3/32",1/32" and 1 / 1 6 " 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"

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
cov e r virt u a l ly ev e r y pos s i ble ki n d of
gri n d ing a pplication. 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 cu t te rs normally are ground wi t h
aluminum oxide wheels. 1/8" shank.
Silicon Carbide Grinding Stones
(blue/green)
Tougher than aluminum oxide points, these
are ma d e e s pecially fo r u s e o n h a r d
mat e r i als suc h as glass an d ce r a m i cs.
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 g old, cooper and brass. The
carbon wire brushes are good for general
purpose cleaning.

Bristle Brushes
These a r e excellent cleaning t o o l s on
silverware, jew elry and antiques. The three
shapes make it possible to get into tight
corners and other difficult places. Bristle
brushes c a n be used with po l i s h i n g
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 br u s h f a c e 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 polishi ng wheel , all u sed for
polishing plastics, metals, jewelry and small
pa r ts. Al s o inc l uded i n this grou p is a
polishing compound (No. 421) for use with
the felt and cloth polishers.
Polishing points ma k e a very sm o o t h
surface, but a high luster is obtained using
felt or c l o t h wheels and polishing
co m pound. For be st re s ults p o lishing
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 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

Mandrel No. 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.
Ma ndrel No. 4 01 is used with the fel t
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.
