Takes a beating in tough stainless without chipping, and the 8% cobalt content really seems to extend the tool life compared to standard HSS. The center-cutting design is a nice bonus for plunge roughing work.

Jacob F. ★★★★★ Oct 20, 2026

Finally, a roughing end mill that doesn't chatter through tough stainless. The M42 cobalt holds an edge noticeably longer than my usual HSS ones. These center-cutting flutes clear chips fast, too.

I was tired of end mills chipping out on tough stainless jobs, but this M42 cobalt roughing mill handles it beautifully. The center-cutting design and uncoated surface let me run at higher feeds without any binding issues.
