I have been searching on here and centurion cutters seem to be very poplular. I want to try some just cant decide on the plunge end or the FEM(flat end mill) end. Any suggestions? I have been using whiteside 1/4" compression bits in my 2.2kw spindle so far but want some 3/8" cutters.

On a side note what would be a suggested feed/rpm, cut depth for a 2.2kw spindle on a machine similar to a prt standard? Its actually a cnc routerparts pro with nema 34s and an atc spindle. Right now I can run a single pass in 3/4" maple plywood at 350ipm and 13,500rpm with the 1/4" compression. I want the 3/8" for a better edge finish.
