Operating Instructions
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 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 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
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 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

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.

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 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
storage. If you do not use the hanger, remove it
from the tool and snap it back into place
underneath the cord so it will be out of the way
while the tool is in use.
