Rotary Power

Too

The Rotary Toot is a handful of high-speed

power It serves as a carver, a grinder,

polisher, sander, cutter, power brush, drilt and

The Rotary Tool has a small, powerful electric

motor, is comfortable in the hand, and is

made to accept a targe 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 ust how versatile the

Rotary Tool is You f 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 dril 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 electdc drill is a low-

speed, high torque too!; the Rotary Tool is ust

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 appty pressure to the tool, but

simply hold and gu{de it tn 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

culling hardened steel, engraving gtass, etc

Getting the most out of your Rotary Tool is a

ma_ter of learning how to let this speed work

for you

Using the

Rotary Power

TooN

Read the next sections carefully They will

hetp you use your Rotary Tool correctly and

hetp 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. Feel 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 face. Accessories can

be damaged during handling, and can fly

apart as they come up to speed This is net

common, but it does happen

Practice on scrap materials first to see how

the Rotary Tool cuts Keep in mind that the

work is done by the speed of the tool and by

the accessory in the coltet. You should not

tean on or push the tool into the work

Instead, lower the spinning accessorylightly

to the workand 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 little pressure from

your hand Aitow the accessory to do the

work

Usually, it is best to make a series of passes

with the tool rather than attempt to do alt 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 small paint brush Cut a

little material 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

For best control in close work, grip the Rotary

Tool fike a pencil between your thumb and

forefinge_

This is the "handgrip" method of holding the

tool used for operationssuch as grinding a flat

surface or using cutoff wheels

_ When using the steel

saws, cutoff wheels, high

speed cutters or tungsten 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 kickback

causing loss of control resulting in

serious injury. Your second hand should

be used to steady and guide the hand

holding the tool. 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 Too_ should be regulated. Only a full

wave output speed control such as the Sears

Model 2514 (available from catalog only)

shoutd be used with the Modet 572.610520

Models 572610530 & 572610720 Rotary

Tools have an integral speed control and an

external speed control should never be used

with these tools

To select the right speed for each job, use a

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:

singte speed, two-speed and variable speed

models On the single speed model, there is

an ON-OFF switch_ When the switch is on,

the toot 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 too] runs at about 20,000 RPM

When the switch indicator is on the high

setting, the toot 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 seiect 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

or 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, all models of

the Rotary Tool should be used at top speed

Needs for Slower Speeds

Certain materials, however, (some plastics,

for example) require a retatively slow speed

because at high spend the friction of the tool

generates heat and causes the plastic to melt

Slow speeds (15,000 RPM or less) usually

are best for polishing operations employing

the felt polishing accessories They may also

be best for working on de_icate projects as

"eggery" 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 controlted by

setting this indicator on the housing
