A die grinder
also commonly called a Dremel (a brand name) or tooth doctor
is a hand held tool equipped with various dies used for
trimming, cutting, and shaping objects. Often when
used in an automotive purpose the die grinder is equipped
with a metallic cone shaped die and is primarily used in
de-burring metal. These tools are useful when cutting
pipe and fabricating steel objects. Other dies can
include various stones, polishing dies, and sandpaper grits.

Die
grinders are rated usually on their unloaded speed
and air CFM. These tools can draw a lot of air
so make sure your air compressor can handle the
required air volume and pressure.
When running a die
grinder, it is important to follow some simple
safety rules. Never wear loose jewelry while
operating the grinder. Neck chains can easily become
caught in the die grinder and cause strangulation.
Safety goggles
should also be worn at all times.
The operator must keep a
strong hold on the die grinder at all times. Similarly, the
component being ground should be held in a bench-top vice or
clamp. Fingers should be kept out of range of the die
grinder.
Recommendation
If you have a
capable
air compressor and
fabricate your own stuff you will use one of these.
The straight models are easiest to hold on to but an angled
one will save the day.
