I have a lathe job, 17-4 PH. 1 5/8 turned down to 5/8, 3" long. Anybody have recommendations for insert grade, speeds, feeds doc? I have made this part in the past using Sandvik 2025, 375 SFM, .011 feed, .1 doc. The problem is the insert life varies so much, may get 50 pcs per edge or 15. Any ideas?
