The Rotary Tool is a handful of high-speed power. It
serves as a carver, grinder, polisher, sander, cutter,
power brush, drill and more.
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, and cutting wheels. 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 33.000 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 chief 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, that makes the
Rotary Tool different from other power 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.
