Value Collection MSC-04662110 Pipe Tap 1-1/2 Npt Hss

Product Description

The VALUE COLLECTION MSC-04662110 is a standard NPT pipe tap designed to cut internal tapered pipe threads in metal workpieces. Sized at 1-1/2 to 11-1/2 NPT, it produces threads that conform to National Pipe Taper standards, making it suitable for creating leak-resistant pipe connections in plumbing, HVAC, and mechanical piping systems. The tap is manufactured from high-speed steel (HSS) and features a bright, uncoated finish. With 7 flutes and a thread length of 1.75 inches, it is built for use in production and maintenance tapping operations. Licensed machinists, pipefitters, and mechanical contractors are the primary users of this tool.

This pipe tap is used when threading holes that will receive tapered NPT fittings in ferrous and non-ferrous metals. Typical applications include threading pipe flanges, manifolds, valve bodies, and mechanical housings that require NPT-threaded ports. The 1-1/2 to 11-1/2 NPT size is common in larger-diameter piping installations found in commercial HVAC systems, industrial fluid handling, and heavy plumbing rough-in work. The regular hook geometry suits general-purpose machine and hand tapping in a range of materials.

Key Features

• 1-1/2 to 11-1/2 NPT thread size for standard tapered pipe thread applications
• High-speed steel construction provides durability across a range of metal workpiece materials
• 7-flute design distributes cutting load and helps maintain thread form accuracy
• Bright, uncoated finish is suitable for use with cutting fluids and oils
• 1.75-inch thread length accommodates standard NPT engagement depth
• Regular hook geometry supports both machine tapping and hand tapping operations

Compatibility

Designed as a standard replacement or production pipe tap for use in any machine or hand tapping setup that accepts a 1.5000-inch shank diameter with a 1.1250-inch square drive, producing 1-1/2 to 11-1/2 NPT threads per ANSI pipe thread standards.

Installation Notes

Pipe taps of this size are typically operated by machinists or pipefitters using a tap wrench, drill press, or tapping machine. Always ensure the workpiece is securely clamped and the pilot hole is drilled to the correct tap drill size for 1-1/2 NPT before beginning the tapping operation. Apply an appropriate cutting fluid throughout the process and back off periodically to clear chips. Power down any machine tooling completely before installing or removing the tap from its holder.
