Cleveland C56703 Npt Pipe Tap 1/4-18 4 Flute Hss Tin

Product Description

The CLEVELAND C56703 is a standard NPT pipe tap designed to cut 1/4-18 tapered pipe threads in ferrous materials. Made from high speed steel with a titanium nitride (TiN) coating, it produces accurate, clean threads suited for pipe fitting and fluid system connections. The 4-flute geometry provides balanced cutting action and chip evacuation during tapping operations. With an overall length of 2.4375 inches and a thread length of 1.0625 inches, the C56703 is built for production and maintenance tapping in metalworking and mechanical trade environments. It is installed by machinists, pipefitters, and HVAC or plumbing technicians threading pipe ports in metal components.

This tap is intended for threading 1/4-18 NPT tapered pipe ports in cast iron, stainless steel, and carbon steel workpieces. Typical applications include creating threaded ports in manifolds, valve bodies, pump housings, and mechanical equipment enclosures where NPT pipe fittings must be installed. The TiN finish reduces friction and extends tool life in repetitive tapping cycles. The Series 965TN designation identifies it within the Cleveland standard pipe tap product line.

Installation Notes

Pipe taps should be installed by qualified machinists or trade professionals using appropriate tap wrenches or machine tapping fixtures. Ensure the workpiece is securely fixtured and the tap is started straight and perpendicular to the drilled pilot hole to prevent thread damage or tap breakage. Apply cutting fluid appropriate for the workpiece material to reduce heat and extend tool life. Follow applicable shop safety practices when operating tapping equipment.
