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. 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.
Switch Setting Speed Range
0 OFF Position
2 5,000 – 10,000 RPM
* 4 10,000 – 14,000 RPM
6 14,000 – 18,000 RPM
8 18,000 – 22,000 RPM
10 22,000 – 25,000 RPM
*4 is the maximum speed setting for wire brushes.
Ultimately, the best way to determine the correct speed
for work on any material is to practice for a few min-
utes 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.)
