Precision Twist Drill 1010522 Pipe Tap 1/2-14 Npt

Product Description

The PRECISION TWIST DRILL 1010522 is a straight flute pipe tap from the 1541 Series, designed to cut internal NPT threads in pipe fittings, valves, and threaded ports. It features a 1/2-14 NPT thread profile and a 1.5-inch depth of cut, making it suitable for through-hole and blind-hole tapping in metal pipe and fitting applications. The medium hook geometry promotes controlled chip flow and consistent thread engagement. This tap is a hand and machine tool used by plumbers, pipefitters, HVAC technicians, and maintenance trades working with threaded pipe connections.

The 1010522 is appropriate for tapping 1/2-inch NPT threads in ferrous and non-ferrous metals commonly found in plumbing, HVAC piping, and industrial pipe assemblies. Its 1541 Series straight flute design suits lower-ductility materials where a spiral flute is not required. The overall length of 3.125 inches provides adequate shank engagement in standard tap handles and machine tool holders. This tap is sold individually.

Installation Notes

Pipe taps are installed by licensed plumbers, pipefitters, and qualified HVAC technicians working with threaded pipe systems. Always apply cutting fluid appropriate for the workpiece material to extend tap life and improve thread quality. Secure the workpiece and use a calibrated tap handle or tapping machine to maintain axial alignment and prevent tap breakage. Follow applicable codes such as the IPC or IFGC when creating threaded connections in pipe systems.
