For best control in close work, grip the Rotary Tool
like a pencil between your thumb and forefinger.
The “handgrip” method of holding the tool is used for
operations such as grinding a flat surface or using
cutoff wheels.
Operating Speeds For Accessories
Set the speed indicator to fit the job to achieve the
best job results when working with different
materials.
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.
Your Cordless RotaryTool is equipped with a variable
speed control dial. To turn the tool ON, rotate dial to
desired number to select the operating speed needed
from 5,000 – 35,000 RPM. To turn tool OFF, rotate
dial to the “0” off position.
You can refer to the charts on page 13, 14, and 15 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
accessory and the optimum speed at a glance.
Needs for Slower Speeds
Certain materials, however, (some plastics, for ex-
ample) require a relatively slow speed because at high
speed the friction of the tool generates heat and caus-
es the plastic to melt.
Most work is done at high speed on your Cordless
Rotary Tool. Lower speeds are needed only for certain
tasks.
Using the Cordless Rotary Tool
The first step in learning to use the Cordless 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 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 not common, but it does happen.
Practice on scrap materials first to see how the Cordless
Rotary Tool cuts. Keep in mind that the work is done by
the speed of the tool and by the accessory in the collet.
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. Con-
centrate on guiding the tool over the work using very lit-
tle pressure from your hand. Allow the accessory to do
the work.
Usually, it is best to make a series of passes with the
tool 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 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.
