ANEWJN-PTI-PTHSS N-Type Pipe Interrupted Tap PT N-PT-INTSold0pcsThe WJ HSS N-Type Pipe Interrupted Tap PT N-PT-INT is the interrupted-thread version of the N-type pipe tap: the crest is deliberately broken up, turning a continuous thread into segments to reduce tapping torque. Whether the crest is continuous is the difference: interrupting it reduces the number of engaged threads and noticeably lowers torque, which matters most in large pipe sizes or hand tapping. The trade-off is less flank contact, so entry and concentricity need more care. Substrate is the same uncoated HSS rated to HRC30; if torque is not a problem go back to the N-type pipe tap N-PT; for better chip evacuation choose the N-type spiral pipe tap N-PT-SFT. Substrate HSS, uncoated, rated to HRC30. It cuts PT/Rc tapered pipe threads, in sizes covering nominal size 1/16"~1", 7 variants. Made in Taiwan. Does an interrupted tap leave an incomplete thread? No - the thread in the workpiece is a full pipe thread; it is the crest on the tool that is interrupted, not the thread in the part. When is it most useful? Large pipe sizes, machines short on torque, or hand tapping that is simply too hard. Typical applications: threading large pipe sizes, tapping where machine torque is limited, and hand-tapped pipe threads.
