With HSC machining, the centrifugal forces produce consid-
erably more stress on the tool than the cutting forces.

Note safety rules enclosed to the tool. Centrifugal forces generated are dependant
upon tool diameter and rotational speed
Milling / Technical information Revolutions per minute increase times two =
(rpm), example: indexable insert of 12g.

centrifugal force increase times four.
