Pipe/Conduit Thread Tap 1/4 -18 HSS MPN:385789

Interrupted-thread taps provide more space for chip evacuation than taps with a standard thread pattern, which allows large chips to be cleared from the taps during threading applications. They have an interrupted thread pattern in which every other tooth has been removed from the cutting edge.
