Four straight flutes are ground for rapid chip removal and efficient hand threading in a variety of materials. The tap produces a class 2B thread, has a straight shank, right-hand threading, 3 to 5 chamfered threads, and is intended for routine maintenance, repair, and rethreading where extremely high thread accuracy is not critical. Material: HCS.
