I am going to be cutting some 718 inconel soon and I am needing some info on endmills. I am only cutting 12pcs that reqiure some roughing/finishing (about .400dp cut) of a profile and some roughing/finishing of some internal pockets with .250 radi. Should I just use regular old HSS endmills or some coated ones. Any ideas about feeds and speeds with them? Is there a better brand of endmill to use? Lee
