Just looked it up. 350RPM is recommended speed. sounds perfect to me.


The forces which are trying to tear the cutter apart go up with the square of
the speed. Thus at 20,000 rpm, the forces are over 3265 times what they
would be at 350 rpm.




And I worry about the forces my arm exerts on a case cutter when slicing
open those damn blister packs! Every time I wield the CC, I think of
the stats of ER visits due to injuries suffered while opening such packages.
