I have 2 double ended lathe cutters that came in a lot I bought. The only markings are to identify each end & read: UNDER 1/2" DIA., 1/2" TO 1 1/4" DIA., 1 1/4 TO 3 DIA., 3" DIA & OVER.
The only difference I can find in comparing all 4 ends is in the rake of the angle leading to the tip. Sorry for the pics as I could not capture the marking with my camera.
