The bright finish on these taps provides a smooth, polished surface.

The black-oxide finish on these taps retains lubricants to improve the taps' wear resistance and chip flow. Black-oxide taps should only be used on ferrous metals.

The TiCN coating on these taps protects them from wear and is harder and more wear-resistant than a TiN coating. Non-coolant-through taps do not have coolant holes, so a separate hose is required to bring coolant to the cutting area if it is needed.

The TiN coating on these taps protects them from wear and allows them to be used at higher speeds than taps with a bright finish. Coolant-through taps have holes that allow coolant to flow to their tip to reduce heat and friction during threading tasks.

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. Coolant-through taps have holes that allow coolant to flow to their tip to reduce heat and friction during threading tasks.
