Use recommended coolants and direct flow to the point of cutting.
Consult the coolant suppliers for specific recommendations.
Adequate cooling is essential to prevent overheating of the cutter
and failures associated with overheating.
Always use drive keys between the cutter and the arbor; friction
between the cutter and the arbor bushes is seldom sufficient
when cutters are under correct load.
Never force a cutter onto a arbor or over an ill-fitted key. Protect
your hands by wrapping the cutter in a soft material when fitting
or removing it from the arbor.
Due to the brittle nature of hardened tool steels it is not advisable
to “remove” a cutter with a mallet once it has been tightened onto
the arbor.
Maintain cutters in sharp condition. Regrind as soon as wear
becomes apparent.
Store cutters carefully when not in use, using a light film of oil to
prevent rusting.
Cleanliness of cutters and arbors is essential.
Use helically fluted cutters wherever possible to minimise shock
as teeth contact the workpiece.
