FIXING STUCK COLLETS – It is possible for a
collet to get stuck within the collet nut especially if
a collet nut is tightened onto the tool without a bit
in place. If this happens, the collet can be
removed from the collet nut by pushing the shank
of an accessory into the hole in the collet nut.
This should cause the collet to pop out of the
collet nut.
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

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

its weight and balance. Feel the taper of the
housing.
