I have been getting along with the above material because it's been easy to get. All turning is done in a split bed Hardinge with sound bearings, tight ways with little wear and very sharp HSS cutters with 1/32 radius tips.

Hardened steel prevents knife blades from dulling and tools from bending and breaking. With a simple heating and quenching process, you can make your steel Machinability of tool steels - slideshare.netNov 22, 2014 · Tool steel Gears Gear that function in a hot or abrasive environment are sometimes made of a hot-work tool steel such as H11, H12, or H13. Milling is the gear production process most used. One of three procedures is followed, the choice of procedure depending largely on whether the primary requirement is abrasion resistance or heat
