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 con-
trol.
Electrical safety
Power tool plugs must match the outlet. Never mod­ify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified
plugs and matching outlets will reduce risk of electric shock.
Avoid body contact with earthed or grounded sur-
faces 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 suit-
able 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.
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.

Personal safety
Stay alert, watch what you are doing and use com­mon sense when operating a power tool. Do not use a power tool while you are tired or under the 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 switch is in the off-position before connecting to power source and / or 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.
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 not force the power tool. 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 differ-
ent 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 bat-
tery 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 cre-
ate 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 objects 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 power 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 use accessories 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 accessory 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 spindle or col­let of the power 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 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 accessory, position yourself and bystanders away from the plane of the rotating accessory and run the power tool at maxi-
mum no-load speed for one minute. Damaged
accessories will normally break apart during this test time.
Wear personal protective equipment. Depending on application, use face shield, safety goggles or safe­ty glasses. As appropriate, wear dust mask, hear­ing protectors, gloves and workshop apron capable of stopping small abrasive 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 power tool by insulated gripping surfaces only, when performing an 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 accesso-
Safety Rules for Rotary Tools
1600A012FR_7000 2/1/17 10:10 AM Page 4

ry 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 adjust-
ment 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 not operate the power tool 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 modifica-
tion 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, sharp edges etc. Avoid bouncing and snagging the acces­sory. Corners, sharp edges or bouncing have a ten-
dency 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 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 cutting-off operations:
Use only wheel types that are 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.
1600A012FR_7000 2/1/17 10:10 AM Page 5

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 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 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 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. 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 bris-
tles 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.

Battery Care
When batteries are not in tool, keep them away from metal
objects. For example, to protect terminals from short-
ing DO NOT place batteries in a tool box or pocket with nails, screws, keys, etc. Fire or injury may result.
DO NOT PUT BATTERIES INTO FIRE OR EXPOSE TO HIGH HEAT. They may explode.
Alkaline Battery Disposal
Commercially available alkaline cells can be dis­posed of in a municipal solid waste stream.
Additional Safety Warnings
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 tool since internal wires may be misplaced or pinched or safety guard return springs may be improperly mounted. Certain cleaning agents
such as gasoline, carbon tetrachloride, ammonia, etc. may damage plastic parts.
Ensure the switch is in the off position before insert­ing battery pack. Inserting the battery pack into
power tools that have the switch on invites accidents.
Some dust created 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.
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.

COLLET NUT— To loosen, first press shaft lock button
and rotate the collet nut by hand until the lock engages the shaft preventing further rotation.
Do not engage lock while the
Tool is running.
With the shaft lock engaged, loosen the collet nut by hand. Change accessories by inserting the new one into the collet as far as possible to minimize runout and unbalance. With the shaft lock engaged, finger tighten the collet nut until the accessory shank is gripped by the collet. Avoid excessive tightening of the collet
nut when there is no bit inserted. COLLETS — Four different size collets (see illus -
tration), to accommodate different shank sizes, are avail able for your Cordless Rotary Tool. 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 which matches the shank size of the accessory you plan to use. Never force a larger diameter shank into a collet.
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.
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 Cordless 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,
COLLET IDENTIFICATION CHART — Collet sizes can be identified by the rings on the back end of collet.

Operation Instructions
Introduction
The Cordless Rotary Tool is a handful of high-speed power. It serves as a carver, a grinder, polisher, sander, cutter, power brush, drill and more.
Your Cordless Rotary Tool has a small, powerful elec tric 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, and cutting wheels. Accessories come in a variety of shapes and permit you to do a num ber of different jobs. As you be come familiar with the range of accessories and their uses, you will learn just how versatile your Cordless Rotary Tool is. You’ll see dozens of uses you hadn’t thought of before now.
The real secret of the Cordless 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 typical electric drill is a low-speed, high torque tool; the Cordless Rotary Tool is just the opposite — a high-
speed, low torque tool. The chief 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 pres sure to it, as you do, for example, when drilling a hole.
It is this high speed, along with its compact size and wide variety of special accessories, that makes your Cordless Rotary Tool differ ent from other power tools. The speed enables it to do jobs low speed tools cannot do, such as en graving glass, etc.
Getting the most out of your Cordless Rotary Tool is a matter of learning how to let this speed work for you.
with the wheel point secured in the collet, turn on the Cordless Rotary Tool and run the 415 Dressing Stone (not included, available as accessory) lightly against the revolving wheel point. This removes high spots and trues up the wheel point for good balance.
Remember, your new Dremel Cordless Rotary Tool is the finest power tool of its kind. But its performance
is only as good as the accessories with which it is used. We recommend only Dremel accessories be used. Use of any other accessories may create a haz­ard. We hope you’ll enjoy many years of trouble free pleasure from your Dremel Cordless Rotary Tool.

For best control in close work, grip the Rotary Tool like a pencil between your thumb and forefinger.
The “handgrip” method of holding the tool is used for operations such as grinding a flat surface or using cutoff wheels.
Using the Cordless Rotary Tool
The first step in learning to use the Cordless 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 the tool to be grasped much like a pen or pencil.
When you turn on the tool for
the first time, hold it 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. Practice on scrap materials first to see how the Cordless
Rotary Tool cuts. 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 into the work.
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 deft, 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 For Accessories
Set the speed indicator to fit the job to achieve the best job results when working with different ma te rials.
To select the right speed for each job, use a practice piece of material. Vary speed to find the best speed for the accessory you are using and the job to be done.
On the Model 7000, there is a LO and HI switch. When the switch indicator is in position 1 or LO, the tool runs at about 7,000 RPM. When the switch indicator is in position 2 or HI, the tool runs at about 16,000 RPM.
You can refer to the charts on pages 16 and 17 to deter­mine the proper speed, based on the materi al being worked and the type of cutter or other accessory being used. These charts enable you to select both the cor­rect acces sory and the optimum speed at a glance.
Needs for Slower Speeds
Certain materials, however, (some plastics, for ex ­ample) require a relatively slow speed because at high speed the friction of the tool generates heat and caus­es the plastic to melt.
Most work is done at high speed on your Cordless Rotary Tool. Lower speeds are needed only for certain tasks.
The speed of Model 7000 is controlled by setting this indicator on the housing.

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 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
The Dremel EZ Lock makes accessory changes easy as PULL - TWIST - RELEASE. The one-piece mandrel design simplifies the process of changing cutting wheels, buffs and detail abrasive brushes (EZ Lock compatible accessories).
EZ Drum™ Mandrel No EZ407SA
The Dremel EZ Drum makes accessory changes easy as PULL - INSERT - PRESS DOWN. The one-piece mandrel design simplifies the process of changing sanding bands.
Use only Dremel®, high-performance accessories. Other accessories are not designed
for this tool and may lead to personal injury or property damage.
Store accessories in a dry and temperate environment to avoid corrosion and deterioration.
The number and variety of accessories for the Rotary Tool are almost limitless. There is a category suited to almost any job you might have to do and a variety of sizes and shapes within each category which en ables you to get the perfect accessory for every need.

High Speed Cutters
Available in many shapes, high speed cutters are used in carving, cutting and slotting in wood, plastics and soft metals such as aluminum, copper and brass. These are the accessories to use for freehand routing or carving in wood or plastic, and for precision cut­ting. Made of high quality steel. 1/8" shank.
Tungsten Carbide Cutters
These are tough, long-lived cutters for use on hard ­ened steel, fired ceramics and other very hard ma ­terials. They can be used for engraving on tools and garden equipment. 1/8" shanks.
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 resharp­ened 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 materi-
als: stainless steel, brass and carbon wire. The stain­less steel perform well on pewter, aluminum, stain­less steel, and other metals, without leaving "after­rust". 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.
INCORRECT:
Excessive pressure can cause wire breakage.
CORRECT: Wire tips doing the work.

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 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 makes it possible to shape wood, smooth fiberglass, sand inside curves and other diffi 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 sold together. All buffs are sold individually. Do not
exceed 15,000 RPM in speed. 1/8" shank.
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.

Replacing Screw Mandrel Accessories
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.
Mandrel No. 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.
