The smaller ones get wiped out by the backside of the threading insert I'm using. We've clearanced the backside quite a bit, and are working on even more but I don't think the tip will hold up. Has anyone here done something similar? What tools have you seen/used to make grooves like this. I'm pulling my hair out on this one. Any help would be greatly appreciated.
