INSTALLING AND REMOVING
ACCESSORIES FROM HAND PIECE WITH
COLLETS
(Not included in all kits)
COLLETS — Four different size collets (see
illustration), to accommodate different shank
sizes, are available for your Rotary Tool. To
install a different collet, remove the collet nut
and remove the old collet. Insert the unslotted
end of the collet in the hole in the end of the
tool shaft. Replace collet nut on the shaft.
Always use the collet which

matches the shank size of
the accessory you plan to use. Never force a
larger diameter shank into a collet.
Note: Most rotary tool kits do not include all four
collets sizes.

Operating Instructions
Rotary Tool Introduction
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 23,000 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 differ-
FIG. 8
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
check our website at www.Dremel.com.
BIT
Do not operate the flexible shaft with a
sharp bend. Over bending the shaft can
generate excessive heat on the jacket or hand
piece. The recommended minimum is 5"
radius.
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.
For best control in close work, grip the Rotary
Tool like a pencil between your thumb and
forefinger (Figure 9).
