Rotary Power
Tool
The Rotary Tooi is a handful of high-speed
power !t serves as a carver, a grinder,
polisher,
Sander, cutter, power brush, dril! and
more
The Rotary Tool has a smali, poweriul elsclrfc
motor, is comfortable in the hand, and is
made to accept a large variety of accessories
including abrasive wheeis, drill bits, wire
brushes, polishers, engraving cutters, router
bits, and cutting wheels Accessories come irt
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 now
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 driit 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 eiectric drill is a iow-
speed, high torque too!; 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 doss the
work. You don’t appiy pressure to the tool, but
simply hold and guide it In the iow speed
tools, you not only guide the toot, 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 toots cannot do, such as
cutting hardened steel, engraving glass, etc.
Getting the most out of your Rotary Tod Is a
matter of learning how to let this speed work
for you
Using the
Rotary Power
Too!
Read the next seciions carefully They will
help you use your Rotary Tool correctly and
help you
Select the correct accessory for your
job
..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. Feet the
taper of the housing. This taper permits the
Rotary Tool to be grasped much like a pen or
pencil
When you turn on the tool for the first time,
hold it away from your lace. Accessories can
be damaged during handling, and can fly
apart as they come up to speed This is not
common, but it does happen
Practice on scrap materiats first to see how
the Rotary Tooi cuts. Keep in mind that the
work is done by the speed of the tool and by
the accessory in the coitet. You should not
lean on or push the tool into the work
Instead, lower the spinning accessory lightly
to the work and allow it to touch the point at
which you want cutting (or sanding or etching,
etc) to begin. Concentrate on guiding the tool
over the work using very iittie pressure from
your hand- Allow the accessory to do the
work-
Usually, it is best to make a series of passes
with the tooi rather than attempt to do all the
work In one pass To make a cut, for example,
pass the tool back and forth over the work,
much as you would a smali paint brush Cut a
little materiai on each pass until you reach the
desired depth. For most work, the deft, gentle
touch is best With it, you have the best
control, are less likely to make errors, and will
get the most efficient work out of the
accessory.
Tooi like a pencil between your thumb and
forefinger.
This is the "handgrip" method of holding the
tool used for operations such as grinding a flat
surface or using cutoff wheels.
SitIWftHNJNGi
When using the steel
saws, cutoff wheels, high
speed cutters or tungstett carbide cutters,
always have the work securely clamped.
Never attempt to hold the work with one
hand
while using any of these
accessories. The reason is that these
wheels will grab if they become slightly
canted in the groove, and can kfckback
causing loss of control resoiting in
serious injury. Your second hand should
be used to steady and guide the hand
holding the took When a cutoff wheel
grabs, the wheel itself usually breaks.
When the steel saw, high speed cutters or
tungsten carbide cutter grab, it may Jump
from the groove and you could lose
control of the tool

Operating Speeds
& Accessories
Set the speed indicator to fit the job; to
achieve the best job results when working
with different materials, the speed of the
Rotary Toot should be regulated. Only a full
wave output speed control such as the Sears
Model 2514 {available from catalog only)
should be used with the Model 572.610520,
Models 572.610530
& 572.610720 Rotary
Tools have an integral speed control and an
external speed control should never be used
with these tools

practice piece of material. Vary speed to find
the best speed for the accessory you are
using and the Job to be done
There are three basic types of Rotary Tools:
single speed, two-speed and variable speed
models On the single speed model, there is
an ON-OFF switch. When the switch is on,
the tool runs at 28,000 RPM On the two-
speed-mode!, there Is a LO and H! switch.
When the switch indicator Is on the low
setting, the tool runs at about 20,000 RPM.
When the switch indicator is on the high
setting, the tool runs at about 30,000 RPM,
On the variable speed model, there is a
switch indicator with a white line on it. Slide to
the number on the housing to select the
operating speed needed from 5,000 - 30,000
RPM You can refer to the charts on page 5 to
determine the proper speed, based on the
material being worked and the type of cutter
Of other accessory being used These charts
enable you to select both the correct acces­
sory and the optimum speed at a glance
If you have a single-speed or two-speed
model, you will be able to use many
accessories to do a wide assortment of Jobs.
For the majority of applications, ai) models of
the Rotary Tool should be used at top speed
Needs for Slower Speeds
Certain materials, however, (some plastics,
for example) require a retativeiy slow speed
because at nigh speed the friction of the tool
generates heat and causes the plastic to meit
Slow speeds (15,000 RPM or iess) usually
are best for polishing operations employing
the felt polishing accessories. They may also
be best for working on deticate projects as
"eggsry" work, delicate wood carving and
fragile model parts You should always do
polishing with wire brush accessories at
slower speeds and never higher than 15,000
RPM
Higher speeds are better for carving, cutting,
routing, shaping, cutting dadoes or rabbets In
wood
Hardwoods, metals and glass require high
speed operation, and drilling should also be
done at high speeds
The speed of the Rotary Tool is cortlrolled by
setting this indicator on the housing,
