anyone using the tormach modular insert end mills? particularly interested in the 25mm 3 flute using the aluminum specific inserts on 6061 for general stock removal and maybe pocketing. can they take a decent cut? i currently run a cobalt 3 flute 3/4" rougher full slot .25" doc at 4000rpm and 20ipm on my series 1 nm200. i have tried lower doc and high feed rates, but all seem to give about the same MRR. looking for something maybe a little faster, and primarily with a repeatable z height and i think these would be the easiest way of doing that. i know tolsa has the press on sleeves for 3/4" tooling, but not crazy about that plan, plus i have a whole 10 pack of the mitsubishi aluminum specific inserts that will fit the tormach stuff and they are just sitting here doing nothing.
