I have a set of M42 0.500" shank Borite bars like these. I'm happy with how they cut. They can be dressed on the flat for sharpness. But I'm curious why they don't make a flat on the shank so the set screw has something to register on vs. obliquely tangent to the shank. This has always bugged me. Yes, I suppose it gives you 'adjustability', but I would prefer 'repeat ability'. They have a similar boring bar set with carbide inserts, same deal, no flats. Dumb question but why?
On a side note I bought an offshore conventional boring bar with CCMT, turned the shank down to 0.500" & preserves the flat so the insert is maintained at correct angle. I'm seriously thinking of just buying more & making my own set at various lengths & shanks.
Any other brands out there I should consider
