Approved to ISO 9001 standards, M.R. Machine Knives’ TiN Coating (Titanium Nitride) is a cost-effective way of increasing the life of the tool that is coated. TiN coating adds a thin film of approximately 2-4 micrometers to the surface of the blade, with a hardness of above 70Hrc, leaving the coating effective to most materials, including:

  • Stainless Steel
  • Tool Steel
  • Carbon Steel
  • High Speed Steel
  • Chrome/Nickel Plated Steels

Serviced at around 500ºc, the coating adds an aesthetically pleasing gold colour to the surface of the steel.

Benefits of TiN coating include:

  • Increased life of cutting tool
  • Decreased downtime on cutting lines
  • Can be re-coated after regrinding or repolishing.
