Hello all, I have a LC4896 with the 5hp HSD ATC. I have broken 2- 1/4" single flute compression spirals, solid carbide. One was and Amana the other a Freud. They both broke 1/8" in side the collet. I am using 18000RPM, 150imp with .25" pass depth in hard maple. They were in two seperate collets any ideas? I can't afford to go through $150 worth of tooling a day. These collets (and the machine for that matter) are just over a month old. Any ideas?!? Thank you.
