Bulk orders will be discounted, please contact us.

The TiAlN coating on these taps withstands high temperatures and protects the taps from wear. It allows the taps to be used at faster speeds than taps with a bright finish, and it resists cracks and oxidation better than TiN or TiCN coatings. 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.
