Single tooth, fully formed for some arbitrary thread I've never been made privy too, so I'm doing SWAG's, Andy. I might be able to define the flat on the tip if I had a calibrated microscope. But I don't. From looking at it, I get the impression it would clean the tops of the cut thread if driven to anything coarser than a 2mm pitch. IMO driving it deep enough to clean the tops of the thread would be abusive, so I use it for finer stuffs.
