These taps are amongst the top quality on the market. This tap is designed for difficult jobs including

the stainless steel family of materials as well as alloy steels, high carbon steel and ductile irons.

Spiral point makes it ideal for through hole applications.

These taps come in packs of 12, however due to the cost per tap, I am selling the taps individually.
