Insert end mills have numerous advantages over solid carbide including price, ability to swap inserts while retaining Z and multiple cutting edges per insert! This one also features through-spindle coolant (!) and the ability to cut square shoulders (e.g. 90 degrees).
The question is can we make this larger diameter insert cutting work on the Tormach PCNC 1100? How will it perform compared to the 1/4" Solid Carbide tooling we've been using from LakeShore Carbide?
