Been having trouble threading I.D. > 304L stainless vim/var <,keeps chipping tip of insert. Using ic 528 grade Iscar I.D. insert .The thread is 1-16 tried all the recommended sfpm.Only getting about 4 parts/per insert.Using a g76 cycle
depth of .005 to .008 on first pass..005 seems to do best but takes alot of passes at that depth.
Any recommendations, on SFPM or I.D. inserts and grades or cutting oils,best suited?
Thanks ,
