Westward 5PXH2 NPT Pipe Tap

The Westward 5PXH2 is a new pipe tap designed to cut internal NPT threads in pipe and conduit. It uses high-speed steel with a bright uncoated finish and a right-hand semi-bottoming chamfer. Four flutes provide chip clearance for general-purpose threading work.

Suits plumbers and mechanics cutting 1/4"-18 NPT

This tap suits plumbers and mechanics who need to create standard NPT threads in pipe or conduit. It is not for buyers who need a different thread form, a different pitch, or a coated tool for high-volume production.

Thread size 1/4"-18 NPT

The single specification that decides fit is the 1/4"-18 NPT thread size. The tap produces a Class 3B fit with a 75 percent thread depth when used with the specified drill size.
