Interrupted thread pipe taps are a type of tap specifically designed for use on external threads on pipes or tubing. This particular interrupted thread pipe tap is made of high-speed steel, featuring five flutes, a bright finish, and complying with the NPT thread standard. It's available in 1 to 11-1/2 inches size increments. The interrupted thread design provides better cutting performance compared to conventional taps due to its self-cleaning action that minimizes clogging caused by chip buildup on the threads. As such, it's ideal for use in oilfield, construction, automotive repair, and many other industries where quality pipe threads are critical.
