Cleveland C64117 Pipe Tap 1/4-18 Nps 4 Flute Hss

Product Description

The CLEVELAND C64117 is a standard pipe tap designed to cut National Pipe Straight (NPS) threads in a range of common materials. With a 1/4-18 thread size, four flutes, and a high speed steel (HSS) construction, this tap produces clean, accurate threads in cast iron, non-ferrous metals including aluminum, and steel. The bright, uncoated finish is suited for general-purpose tapping applications where a coating is not required. Thread length measures 1.063 inches and overall length (OAL) is 2.438 inches. Plumbers, pipefitters, and mechanical tradespeople rely on this style of tap when threading pipe fittings and connections to NPS standards.

This tap is used in residential and commercial plumbing, HVAC piping, and general mechanical installations wherever a 1/4-18 NPS threaded connection is required. It is appropriate for threading ports, fittings, and pipe connections in cast iron, aluminum, and steel workpieces. The regular hook geometry provides consistent cutting action across these material types, making it a practical shop and field tool for licensed plumbers and pipefitters handling threaded pipe work.
