Operating Instructions
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
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. Sharpen Tools Drilling
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 Shape Wood Carve Wood
operates at speeds up to 35,000 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. Deburr Metal Cut Metal
