Cleveland C64116 Pipe Tap 1/8-27 Nps 4 Flute Hss

Product Description

The CLEVELAND C64116 is a standard pipe tap designed to cut internal NPS (National Pipe Straight) threads in a range of common materials encountered in plumbing and mechanical trade work. Ground from high speed steel (HSS) with a bright, uncoated finish, this tap features 4 flutes and a regular hook geometry for controlled cutting action. It threads to a 1/8-27 specification, with a thread length of 0.75 inches and an overall length of 2.125 inches. Plumbers, pipefitters, and mechanical contractors use this tap to thread fittings, couplings, and ported components where a standard pipe thread engagement is required.

This tap is suited for use in residential and commercial plumbing, HVAC piping connections, and general mechanical assembly. It is rated for use in cast iron, non-ferrous metals including aluminum, and steel. The 1/8-27 NPS thread size is commonly found on small-diameter pipe fittings, pressure ports, gauge ports, and instrumentation connections. Single-piece packaging makes it appropriate for job-site use or shop inventory.

Installation Notes

This tap is installed by a plumber, pipefitter, or machinist using a standard tap wrench or machine tapping setup. Always apply an appropriate cutting fluid for the material being threaded to extend tool life and improve thread quality. Secure the workpiece firmly before tapping to prevent movement and thread misalignment. Follow applicable code requirements for pipe thread engagement depth on pressure-bearing connections.
