To select the right speed for each job, use a
practice piece of material.
NOTE: Speed is affected by voltage
changes. A reduced incoming voltage will
slow the RPM of the tool.
(MODEL 100)
On the single speed model, there is an ON-
OFF switch. When the switch is on, the tool
runs at 35,000 RPM.
(MODEL 200)
On the two-speed model, there is a LO and HI
switch. When the switch indicator is on the low
setting, the tool runs at about 15,000 RPM.
When the switch indicator is on the high
setting, the tool runs at about 35,000 RPM.
(MODEL 3000)
On the vari able speed model, there are
switch setting in dicators marked with a line.
Slide to the number on the housing to select
the operating speed needed from 5,000 –
35,000 RPM.
You can refer to the charts on page 24, 25,
26 and 27 to determine the proper speed,
based on the material being worked and the
type of accessory being used. These charts
enable you to select both the correct acces -
sory and the optimum speed at a glance.
The speed of Rotary Tool is controlled by
setting this indicator on the housing.

Needs for Slower Speeds
Certain materials, however, (some plastics and
precious metals, for ex ample) require a
relatively slow speed because at high speed
the friction of the accessory generates heat
and may cause damage to the material.
Slow speeds (15,000 RPM or less) usually are
best for polishing operations employing the felt
polishing ac ces sories. They may also be best
for working on deli cate projects as "eggery"
work, delicate wood carving and fragile model
parts. All brushing applications require
lower speeds to avoid wire discharge from
the holder.
If you need it, single-speed models also
can have speed control by using a Model
221 foot control unit.
Not for use with two
speed or variable speed
models 200 or 3000. Use with external
speed control will damage the variable/two
speed electronics.
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.
You can do the great majority of work with the
single speed at its regular speed of 35,000
RPM. But for certain materials and types of
work, you need slower speeds — which is the
reason the variable speed models are
available.
To aid you in determining the optimum
operational speed for differ ent materials and
different accessories, we have constructed a
series of tables that appear on page 24, 25, 26
and 27. By referring to these tables, you can
discover the recommended speeds for each
type of accessory. Look these tables over and
become familiar with them.
Ultimately, the best way to determine the
correct speed for work on any material is to
practice for a few minutes on a piece of scrap,
even after referring to the chart. You can
quickly learn that a slower or faster speed is
more effective just by observing what hap pens
as you make a pass or two at different speeds.
When working with plastic, for example, start at
a slow rate of speed and increase the speed
until you observe that the plastic is melting at
