Will a .750" 10 flute end mill have enough flute clearnce to use for some hsm tool paths, I currently use a 5 flute for the job that works very well, the material is 17-4ph H1150, up untill now the quanties have been small, but we have an order coming up for 5 times as many as we have ever made before. I asked my tooling guy to get me this 10 flute tool and he was concerned that the chips would plug the flutes and the tool would break. I plan to run it at 1680rpm with a .475 doc and between 10% and 15% stepover starting with a chip thinkness of .004, using radial chip thining so with adjusted feed rates.
