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

back into place so it will be out of the way while
the tool is in use.

Thank you for purchasing the Dremel 8220.
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 8220 is one of the MOST
versatile cordless rotary tool available today. t
has a wide speed range including a high
performance motor that allows the tool to
maintain its speed under load. The design of
the tool also contains plenty of soft grip so the
tool can be held comfortably in many
positions. The quick collet lock mechanism
makes locking the output shaft easier for
changing accessories. You will appreciate the
many applications that the Dremel 8220 can
easily tackle.
)@E2CJ+@@= ?EC@5F4E:@?
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, drill bits, wire
brushes, polishers, engraving cutters, router
bits, cutting wheels and attachments.
Accessories come in a variety of shapes and
permit you to do a number of different jobs. As
you be come familiar with the range of
accessories and their uses, you will learn just
how versatile the Rotary Tool is. You’ll see
dozens of uses you hadn’t thought of before.
The real secret of the Rotary Tool is its speed.
To understand the advantages of its high
speed, you have to know that the standard
portable electric drill runs at speeds up to 2,800
revolutions per minute. The Rotary Tool
operates at speeds up to 30,000 revolutions
per minute. The typical electric drill is a low-
speed, high torque tool; the Rotary Tool is just
the opposite – a high-speed, low torque tool.
The major difference to the user is that in the
high speed tools, the speed combined with the
acces sory mounted in the collet does the work.
You don’t apply pressure to the tool, but simply
hold and guide it. n 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.
t 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. 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.

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

Your tool is equipped with a variable speed
adjuster. The speed may be adjusted during
operation by sliding the adjuster back or forth
between any one of the settings.
You can refer to the charts on page 22, 23,
24 and 25 to determine the proper speed,
based on the materi al 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.
&A6C2E:?8*A665D
For best control in close work, grip the Rotary
Tool like a pencil between your thumb and
forefinger (Figure A).
The “Golf Grip” method of holding the tool can
be used for more aggressive operations such
as grinding a flat surface or using cutoff
wheels (Figure B).
Practice on scrap materials first to see how the
Rotary Tool's high speed action performs. Keep
in mind that the work is done by the speed of
the tool and by the accessory in the collet. You
should not lean on or push the tool during use.
nstead, lower the spinning accessory lightly to
the work and allow it to touch the point at which
you want cutting (or sanding or etching, etc.) to
begin. Con centrate on guiding the tool over the
work using very little pressure from your hand.
Allow the accessory to do the work.
Usually, it is best to make a series of passes
with the tool rather than attempt to do all the
work in one pass. To make a cut, for example,
pass the tool back and forth over the work,
much as you would a small paint brush. Cut a
little material on each pass until you reach the
desired depth. For most work, the gentle touch
is best. With it, you have the best control, are
less likely to make errors, and will get the
most effi cient work out of the accessory.

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. ==3CFD9:?82AA=:42E:@?DC6BF:C6

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.
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 construct ed a
series of tables that appear on page 22, 23, 24
and 25. 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.
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. ron or steel should be cut at high speed. f
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.
ncreasing 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.

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. f 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.
