I understand the ribbing, but I guess none of you understand the basis of the question.
Unlike the brazed carbide tool shown, a CCGT/CCMT insert with it's 80º included angle and be used for turning and facing without rotating the tool 90º. It cuts EXACTLY the same going along a face as it does turning along a diameter.
The only use I'd have for a left hand tool that holds a "C" shape-designation insert is if I was doing a lot of large diameter but shallow I.D. work, or had some very heavy-duty back-turning task that I couldn't handle with the left hand DNMG and VNMG holders I have.
