Use the highest speed when working on steel
or iron with the milling bits.
Use a short trial on a test piece to determine the
optimum rotational speed range for working on
zinc, zinc alloy, aluminium, copper and lead.
Use the low speed range for working on plastics
and low-melting point materials.
Use high speeds on wood.
Use the medium speed range for cleaning,
polishing and buffing.
