Cleveland C64041 Npt Pipe Tap 1/2-14 4 Flute Hss

Product Description

The CLEVELAND C64041 is a standard NPT pipe tap designed to cut internal 1/2-14 National Pipe Taper threads in metal workpieces. With 4 flutes and a high-speed steel (HSS) construction, it delivers consistent thread engagement for pipe and fitting connections. The bright, uncoated finish suits a range of cutting applications without the added cost of specialty coatings. Overall length is 3.125 inches with a thread length of 1.375 inches, making it sized for typical hand-tap or machine-tap use in trade and shop environments. Licensed plumbers, pipefitters, and maintenance machinists are the primary users of this tap.

This tap is suited for threading 1/2-14 NPT connections in non-ferrous materials such as aluminum and in steel. It is commonly used in plumbing, HVAC piping, and industrial maintenance work where NPT-threaded pipe connections are required. The regular hook geometry and 4-flute design support use in both through-hole and blind-hole tapping operations on a bench or in a drill press setup.

Installation Notes

NPT pipe taps should be installed and operated by qualified plumbers, pipefitters, or machinists following applicable shop and trade safety practices. Always apply a suitable cutting fluid when tapping steel or aluminum to reduce heat and extend tool life. Secure the workpiece firmly before tapping to prevent movement under torque. Inspect tap flutes for chips and wear regularly; a damaged tap should not be used as it may seize or break in the hole.
