Speed Controller - Dremel 1100 Operating/Safety Instructions Manual

Adjust the speed of the tool by turning the
speed control dial located at the rear of the
tool. To turn the tool off, press the on/off
button.
You can refer to the charts on page 15, 16,
and 17 to determine the proper speed, based
on the material and 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
example) require a relatively slow speed
because at high speed the friction of the tool
generates heat and causes the plastic to melt.
Most work is done at high speed. Lower
speeds are needed only for certain tasks.
The speed of the tool is controlled by
rotating the speed dial at the back of the
tool.

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 happens
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
the point of contact. Then reduce the speed
slightly to get the optimum working speed.
Some rules of thumb in regard to speed:
1. Plastic and materials that melt at low
temperatures should be cut at low speeds.
2. Polishing, buffing and cleaning with a wire
brush must be done at speeds below
15,000 RPM to prevent damage to the
brush.
3. Wood should be cut at high speed.
4. Iron or steel should be cut at top speed if
using tungsten carbide accessory, but at
slower speeds if using high speed steel
cutters. If a high speed steel cutter starts to
chatter — this normally means it is running
too slow.
5. Aluminum, copper alloys, lead alloys, zinc
alloys and tin may be cut at various speeds,
depending on the type of cutting being
done. Use paraffin or other suitable
lubricant on the cutter to prevent the cut
material from adhering to the cutter teeth.
Increasing the pressure on the tool is not the
answer when it is not cutting as you think it
should. Perhaps you should be using a
different cutter, and perhaps an adjustment in
speed would solve the problem. But leaning on
the tool seldom helps.
Your Dremel Stylus can be used with all of the
Dremel accessories, except router bits. While
the tool will work with cut-off wheels, the
reduced speed of this tool will not allow them
to perform optimally. They can be used to cut
soft materials such as wood or plastic, but
cutting metals is not recommended. The
Stylus tool cannot be used with any of the
Dremel line of attachments (attachments screw
on to the nose of a rotary tool.)
