Because ferritic grades machine like traditional steels, an insert with a chipbreaker designed for general steel turning will suffice. Martensitic stainless steels, which contain 11.5% to 18% chromium and more than 0.013% carbon, are heat-treated for high strength and toughness. They, too, machine like steels but with much higher cutting forces.
When grinding 55A to 80A durometer polyurethanes, use a tool post grinder in an engine lathe. Low turning speeds (below 150 rpm), with the lathe running in reverse will yield the best results. If you're removing lots of material, first turn the piece down with a cutting tool to within .020 of the finished dimension before grinding.
