One of the more recent developments in coatings for High Speed Steel is Titanium Nitride is a bright gold ceramic coating applied to metallic surfaces by the physical vapour deposition (PVD) process. Titanium Nitride is widely used to extend the life of a cutting tool, significantly improve the tool life and performance of cutting tools, where a cost effective reduction in tool wear is required. This coating is known to allow the tool to be used at higher operating speeds. Cutting tool life can be extended by as much as three times, and operating speeds can be increased up to 50%.
