Compared to UNF taps, UNC taps perform better in threading applications on brittle materials and are less likely to cross thread. Coarse threads can also withstand more physical abuse than fine threads. The TiCN coating on these taps protects them from wear and is harder and more wear-resistant than a TiN coating.
