8. Speed selection also depends
on the material being cut, so
trials are suggested on scrap material first.
If material is burning, reduce speed and also pressure on
the tool.
Faster speeds are also suggested for grinding as slower
speeds have a tendency to clog the wheel.
Sanding is performed as fast as possible without burning
the surface of the material.

Holding the tool

1. For jobs such as milling or engraving where precision is
required, hold the mini-drill like a pen.
2. For heavier work like cutting or grinding hold the machine
in the palm of your hand.
