My mill has a top speed of 2500RPM and with the specs on the new cutters that arrived today they have a much shorter flute length. The specs say that HRC60 speed(mm1) is 20000 Feed mm/min 200 I am guessing that the mm1 refers to the speed per tooth and this gives me a chip load of that should mean 25mm/min feed and /min plunge.
