The type of tooling you would use is dependent on the material. HSS will work on most steel in the soft form, carbide for hard and tough alloys. HSS can be ground to a sharper tool. We never went finer than a 60 grit wheel for grinding them, less heat problems and faster stock removal. The best holder by far is the Aloris equivalent quick-change post and holder. You can set up a few different tools on advance and just do a quick change. Hope it helps a little
