33ZH74 Spiral-Flute STI Taps

$59.99

Bulk orders will be discounted, please contact us.

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. Cobalt taps are harder and provide more wear resistance when tapping hard materials at high speeds than high-speed steel taps.
