Cutting Tools All-purpose coating that significantly improves tool life by 2 – 7x over uncoated tools. Can be applied to all types of tools, including drills, taps, end mills, reamers, inserts, dovetails, etc. Materials that can be coated include HSS, M2, M4, T15, tool steels, carbide, stainless steels and other materials. Punching and Forming Tools, Stamping Applications On punches, TiN provides 2 to 10x tool life over uncoated punches. In forming applications, TiN improves tool life and lubricity, reduces friction, and reduces or eliminates galling. Injection Molding TiN-coated mold components last 2 – 8x longer than uncoated. Improved lubricity for faster cycle times. Better abrasion resistance when using glass-filled plastics. Corrosion resistance when corrosive gases are formed in the molding process. Reduces or eliminates galling between sliding mold components. Medical Components Biocompatible, FDA approved for use on medical devices. Use TiN for edge retention on surgical instruments. Improve device aesthetics to differentiate products from those of competitors. Wear Components Use TiN to extend the product life, improve performance and enhance the appearance of a product. Typical applications would be firearm components, knife blades, bicycle parts, etc.
