Speed Control Buttons; Settings For Approximate Revolutions; Needs For Slower Speeds - Dremel Micro Original Instructions Manual

Your tool is equipped with an internal electronic
monitoring system that helps to maximize motor
and battery performance by limiting the current to
the tool when overload and stall conditions occur.
If you stall the tool for too long, or bind the bit in a
work piece, especially at high speeds, the tool will
automatically turn itself off thanks to the fallback
built into it. Once this happens, simply take the
tool out of the material you were stalled in, turn
it back on again, adjust the speed if necessary,
and continue using it. When the battery
becomes close to empty, the tool may shut down
automatically more frequent than normal. If this
happens, it is time to recharge the tool.
SPEED CONTROL BUTTONS
Your Dremel Micro is equipped with speed
control buttons. The speed may be adjusted
during operation by pressing on the plus )+( or
)-( minus blue buttons located on the topside
of the battery housing. Speed will increment or
decrement by 5,000 rpm from a minimum of
5,000 to a maximum of 28,000 rpm. The LED
lights located alongside the blue buttons will
illuminate according to the chosen speed. Every
time the tool is turned off the speed set goes
back to the medium level )15,000 rpm( so it might
be necessary to increase/decrease the speed to
the level that it was being used )e.g. 28,000 rpm(
before the tool was turned off to keep working on
the same application.
You can refer to the charts on pages 4-7 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.
The speed of Rotary Tool is controlled by setting
the blue speed control buttons.

Needs for Slower Speeds
Certain materials, however, )some plastics and
precious metals, for example) 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 accessories. They may also be best for
working on delicate projects as "eggery" work,
delicate wood carving and fragile model parts.
ALL BRUSHING APPLICATIONS
WARNING
!
REQUIRE LOWER SPEEDS TO
AVOID WIRE DISCHARGE FROM THE HOLDER.
Higher speeds are better for carving, cutting,
shaping, cutting dadoes or rabbets in wood.
Hardwoods, metals and glass require high speed
operation, and drilling should also be done at high
speeds.
Many applications and accessories in our line will
provide the best performance at full speed, but for
certain materials, applications, and accessories,
you need slower speeds, which is the reason our
variable speed models are available.
To aid you in determining the optimum operational
speed for different materials and different
accessories, we have constructed a series of
tables that appear on page 4, 5, 6 and 7. 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 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 other materials that melt at low
2. Polishing, buffing and cleaning with any type
3. Wood should be cut at high speed.
4. Iron or steel should be cut at high speed. If a

Increasing the pressure on the tool is not the
answer when it is not performing as you think it
should. Perhaps you should be using a different
accessory, and perhaps an adjustment in speed
would solve the problem. Leaning on the tool
does not help.
Your Dremel Micro 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 Micro tool cannot be used with
any of the Dremel line of attachments )attachments
screw on to the nose of a rotary tool.)

greater than 15,000 RPM to prevent damage

normally means it is running too slow.
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.
