Value Collection MSC-04662136 Pipe Tap 2-11-1/2 Npt Hss

Product Description

The VALUE COLLECTION MSC-04662136 is a standard pipe tap designed to cut NPT (National Pipe Taper) internal threads in metal workpieces. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers reliable thread-cutting performance on ferrous and non-ferrous materials. The 2-11-1/2 thread size designation indicates a 2-inch nominal pipe thread with 11.5 threads per inch, conforming to NPT standards. Seven flutes provide efficient chip evacuation during tapping operations. With a shank diameter of 1.875 inches and a square drive size of 1.406 inches, this tap is sized for use in heavy-duty manual or machine tapping setups. Machinists, pipefitters, and maintenance technicians use this tool when threading large-bore pipe connections in industrial, mechanical, and plumbing applications.

This tap is suited for creating NPT-threaded connections in pipe flanges, fittings, manifolds, and heavy-wall pipe sections requiring a 2-inch nominal thread. It is appropriate for use in industrial maintenance, fabrication shops, and commercial plumbing installations where large-diameter pipe threads must be cut on-site or in a machine shop environment. The 1.75-inch thread length accommodates standard engagement depth for 2-inch NPT connections. Operators typically run this tap by hand with a large tap wrench or under controlled machine tapping conditions to maintain thread accuracy.

Key Features

• 7 flutes for effective chip clearance during deep or production tapping
• Bright, uncoated finish allows visual wear inspection and broad material compatibility
• Shank diameter of 1.875 inches with 1.406-inch square drive for secure tap wrench or machine chuck engagement
• 1.75-inch thread length meets standard NPT engagement depth requirements

Compatibility

Designed as a standard NPT pipe tap for cutting 2-11-1/2 internal pipe threads in compatible metal workpieces, pipe fittings, and flanges.

Installation Notes

This tap is installed and operated by machinists, pipefitters, or maintenance technicians familiar with large-diameter threading procedures. Always secure the workpiece firmly and apply a suitable cutting fluid to reduce heat and extend tool life. Power down any connected machinery and relieve system pressure before tapping into existing pipe assemblies or fittings. Do not force the tap if resistance increases sharply, as this risks tap breakage in large-diameter threads that are difficult to recover.
