Rotary Tool Introduction
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.
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.
Whenever you hold the
tool, be careful not to cover
the air vents with your hand. This blocks
the air flow and causes the motor to
overheat.
narrow end of the new collet completely into the
EZ Change™ chuck. The fingers of the collet
must be aligned with the detents of the EZ
Change™ chuck to be fully inserted.
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 by pulling
back on the EZ Change™ levers and give the
accessory a 1/4 turn. Release EZ Change™
levers 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.
