Yes, pneumatic die grinders are essential, for
detailing, texturing, and finishing, or for
shaping small pieces. Most run at 24,000 rpm.
This is fine for using very small burrs, or
medium burrs when you want to move a lot of
material, or to run SiC sanding discs on
marble for a glazed finish. But most of the
time I find myself turning down the air and
rpm considerably with a valve in the air line,
to maximize control. The problem is when you
do this, you also lose power and torque, which
can cause the wheel to simply stop. If, like
me, you like to do a lot of careful shaping
work with a 2" or 3" diamond grinding wheel,
consider buying a 12,000 rpm angle head die
grinder instead (or in addition). You won't
find one by any cheapie brand that I am aware
of; you'll have to go to an ARO or Dotco etc.
Expensive, but it will last you a lifetime.
With the slower grinder, you retain twice as
much torque at the lower speeds.
