Cobalt steel is a type of high-speed alloy steel used primarily for cutting tools. Introduced to manufacturers in 1900, high-speed steel, containing a mixture of tungsten, chromium, and trace amounts of carbon, enabled manufacturers to double or even triple their production.
Titanium nitride (TiN) coating is wear resistant, inert & reduces friction. Used on cutting tools punches etc improving tool life 2-10x over uncoated tools
