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 12,000 revolu-
tions 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 mount-
ed 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, that makes the Rotary Tool differ ent from
other tools. The speed enables it to do jobs low speed tools can-
not 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

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 han-
dling, and can fly apart as they come up to
speed. This is not common, but it does hap-
pen.
blocks the air flow and causes the motor to overheat.
For best control in close work, use the "Pencil Grip" method by
gripping the rotary tool like a pencil between your thumb and
forefinger (Fig. 5).
The "Golf Grip" method of holding the tool can be used for more
aggressive operations such as grinding a flat surface or using cut-
off wheels (Fig. 6).
Practice on scrap materials first to see how the Rotary Tool's high
speed action performs. Keep in mind that the work is done by the
speed of the tool and by the accessory in the collet. You should
not lean on or push the tool during use.
Whenever you hold the tool, be careful not
to cover the air vents with your hand. This
