The TiCN coating on these taps protects them from wear and is harder and more wear-resistant than a TiN coating. These taps meet DIN length standards and have a longer overall length than taps that meet ISO, ANSI, and JIS length standards. They also meet ANSI shank standards, which means they measure their shank diameter in inches and fit in standard tools used in the U.S. This listing is for each.
