Spiral Flute Tap, 5/8"-18, Bottoming, 4 Flutes, UNF

These taps are designed for tapping alloy steel. They have a TiCN coating that 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. This listing is for each.
