Value Collection MSC-04676052 Extension Pipe Tap 1/2-14 Npt

Product Description

The VALUE COLLECTION MSC-04676052 is a 1/2-14 NPT extension pipe tap designed for cutting internal pipe threads in metal workpieces where standard-length taps cannot reach. Built from high-speed steel with a bright uncoated finish, this tap features 4 flutes and a plug chamfer that distributes cutting load across the leading threads for controlled thread entry. The 6-inch overall length and 0.6875-inch shank diameter make it suited for deep or recessed tapping applications common in plumbing, HVAC, and industrial piping fabrication. Installed by machinists and pipefitters working on threaded pipe fittings and manifold assemblies.

This extension pipe tap is used in applications requiring NPT-standard internal threads in ferrous and non-ferrous metals, including steel pipe fittings, cast iron bodies, aluminum housings, and fabricated manifolds. The plug chamfer style makes it a practical choice for through-holes and semi-blind tapping where a starting chamfer is preferred over a bottoming style. It fits standard tapping machines, drill presses, and tap wrenches equipped to accept the 0.6875-inch shank diameter.

Key Features

• 1/2-14 NPT thread form for standard tapered pipe thread applications
• 4-flute design promotes chip evacuation and balanced cutting action
• Plug chamfer distributes cutting load over the leading threads for controlled entry
• High-speed steel construction provides durability across a range of metals
• 6-inch overall length allows access to recessed or deep tapping locations
• Bright uncoated finish suitable for use with standard cutting fluids

Compatibility

Designed as a standard NPT pipe tap compatible with manual tap wrenches, tapping machines, and drill press setups that accept a 0.6875-inch shank diameter.

Installation Notes

Pipe taps should be installed by qualified machinists or pipefitters familiar with NPT thread standards and proper tapping procedure. Always apply a suitable cutting fluid appropriate for the workpiece material, and ensure the tap is aligned perpendicular to the hole before starting. Back the tap out periodically to clear chips and prevent tap breakage. De-energize and lock out any powered tapping equipment before changing or inspecting the tap.
