Looking for suggestions for tnmg or tngg for turning a2 tool steel. Or maybe I dont need a 0⁰ angle...I really dont know. Also 331 or 332? I have a few lathe projects I want to work on, involving A2, and I've never turned it before, so all suggestions are welcome. One of the projects will have interrupted cuts, the other will not. The A2 is annealed. That's about all the info I can think of, at this time...so....ideas??
