We are looking at turning and broaching some 660D round bar for a 3/4" in hex head specialty cap screw and the tool suppliers haven't been terribly excited about the longevity of their tools in this stuff. We planned to run a rotary broach in a live tool lathe, but we're starting to have second thoughts. Has anyone out there broached 660D? If so, any feedback on the to-do's and to-don'ts would be much appreciated. Thanks.
...but in stainless ?
