Hertel R127700C-S Pipe Tap 3/4-14 Npt 5 Flute Hss Ticn

Product Description

The HERTEL R127700C-S is a standard pipe tap designed to cut 3/4-14 NPT internal threads in metal workpieces. Built from high speed steel (HSS) with a titanium carbonitride (TiCN) coating, this tap delivers improved wear resistance and longer tool life compared to uncoated HSS. The 5-flute design provides more cutting edges per revolution, which promotes smoother thread formation and better chip management. At 3.25 inches overall length, it fits standard tap wrenches and machine setups used in pipe threading operations. Plumbers, pipefitters, HVAC technicians, and machinists use this tap when threading pipe fittings, manifolds, valves, and other components requiring NPT connections.

This tap is suited for creating NPT tapered pipe threads in ferrous and non-ferrous metals across residential and commercial piping, HVAC refrigerant line components, hydraulic systems, and general industrial fabrication. The NPT thread form is a tapered standard widely used in North American plumbing and gas piping applications. The TiCN finish makes this tap well-suited for production environments and repeated use in harder materials where uncoated taps would wear prematurely.

Key Features

• 3/4-14 NPT thread size for standard American tapered pipe thread applications
• High speed steel construction provides toughness and resharpening capability
• TiCN coating improves surface hardness and reduces friction during cutting
• 5-flute design increases cutting edges for smoother thread form and improved chip evacuation
• 3.25 inches overall length fits standard tap wrenches and CNC tapping setups
• Regular hook geometry for general-purpose through and blind hole tapping

Compatibility

Designed for use wherever 3/4-14 NPT internal threads are required. Suitable for hand tapping with a tap wrench or machine tapping in drill presses and CNC machining centers capable of tapping operations.

Installation Notes

This tap should be installed and operated by a qualified machinist, pipefitter, or tradesperson familiar with pipe thread cutting procedures. Always ensure the workpiece is securely clamped and the tap is properly aligned before beginning the cut. Use appropriate cutting fluid for the material being tapped to extend tool life and produce clean threads. Follow applicable facility safety procedures and relevant codes such as ASME B1.20.1 for NPT thread specifications.
