Each can dramatically increase roughing metal removal rates yet provide significantly longer tool life. Highefficiency milling uses solid carbide end mills with small stepovers, but faster feed rates and deeper depths of cut. Highfeed milling is pretty much the opposite. It uses an indexable cutter with a shallow depth of cut, high feed rates ...
