The TiCN coating on these taps protects them from wear and is harder and more wear-resistant than a TiN coating. These taps are made from powdered metal, which has a uniform microstructure and grain distribution that gives the material a similar strength as carbide. Powdered-metal taps are tougher and less likely to break than cobalt and high-speed steel taps. They are used for tapping highly abrasive materials such as high-silicon aluminum.
