Hertel R127164-S Pipe Tap 1/8-27 Nps 4 Flutes Hss

Product Description

The HERTEL R127164-S is a standard pipe tap designed to cut National Pipe Straight (NPS) threads in metal workpieces. It produces a 1/8-27 thread form with four flutes, providing clean chip evacuation and consistent thread quality in a range of materials. The tool is manufactured from high speed steel (HSS) and carries a bright, uncoated finish. With a shank diameter of 0.4375 inches and a square drive size of 0.328 inches, it fits standard tap wrenches and tapping heads used in machining, pipefitting, and plumbing fabrication shops.

This tap is suited for creating straight pipe threads in pipe fittings, manifolds, valve bodies, and hydraulic or pneumatic components. The 1/8-27 NPS thread size is a common specification in light-duty fluid and gas line assemblies. It is typically used by machinists, pipefitters, and plumbers who need to produce or restore threaded ports in metal parts. The 3/4-inch thread length accommodates full thread engagement in standard-depth pipe tap applications.

Key Features

• 1/8-27 NPS thread form for straight pipe thread applications
• Four flutes for efficient chip removal during tapping
• High speed steel construction for durability across common metals
• Bright, uncoated finish suitable for use with cutting fluid
• 0.4375-inch shank diameter fits standard tap wrenches and chucks
• 3/4-inch thread length for full engagement in typical port depths

Compatibility

Designed as an OEM-style replacement or standard tooling option for applications requiring 1/8-27 NPS straight pipe threads in metal components.

Installation Notes

Pipe taps should be installed and operated by qualified machinists or pipefitters familiar with proper tapping procedures. Always use an appropriate cutting fluid to extend tool life and improve thread quality. Secure the workpiece firmly before tapping and align the tap perpendicular to the entry surface to avoid thread misalignment or tap breakage. Back the tap out periodically to clear chips, especially in blind-hole applications.
