The Rotary Tool is a handful of high-speed
power. It serves as a carver, grinder, polisher,
sander, cutter, power brush, drill and more.
The Rotary Tool has a small, powerful electric
universal motor, is comfortable 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 become 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 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
accessory 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 this high speed, along with its compact
size and wide variety of special accessories
and attachments, that makes the Rotary Tool
different from other tools. The speed enables it
to do jobs low speed tools cannot do, such as
cutting hardened steel, engraving 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

Using the Rotary Tool

The first step in learning to use the Rotary Tool
is to get the "feel" of it. Hold it in your hand and
feel its weight and balance. Feel the taper of
the housing. This taper permits the Rotary Tool
to be grasped much like a pen or pencil
(Figure A).
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.
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. 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
