Some more CCMT lathe tools, now I think I have the entire 5/8″ shank “collection” – left hand, neutral, chamfer and boring bar (3/4″). I have commercial right hand tools and 1/2″ boring bar.
It was bugging me that I couldn’t figure out how to make these without clamping more than once. Then I got the idea that I could use the insert corner relief as a reference point and if I drilled it all the way through, a mounting and reference point. So I made the set to test the idea and it worked great.
