To my newly ground MoMax flycutter bit, I added a chipbreaker groove. It does work, but the air die grinder was a bit awkward to use, and the groove wasn't quite right. Not deep enough, and the groove encroached upon the edge in one place. Practice makes perfect.
Harold V - I read your very informative article on chipbreakers, which spoke of some photos. What happened to these photos?
Thanks,
Joe
