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. Retighten 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

Rotary Tool Introduction
The Rotary Tool has a small, powerful electric
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 30,000 revolutions
per minute. The typical electric drill is a low-
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, snap it
back into place so it will be out of the way while
the tool is in use.

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 differ-
ent 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

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.
