Value Collection JY79772687 1/2-14 Bspt Pipe Tap Bottoming

Product Description

The VALUE COLLECTION JY79772687 is a straight-flute British Standard Pipe Tap designed to cut 1/2-14 BSPT internal threads in through-holes and blind holes requiring a bottoming chamfer. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this tap delivers reliable thread-forming performance in ferrous and non-ferrous metals. With 4 flutes and a right-hand thread direction, it suits standard tapping operations where chip evacuation is manageable and thread accuracy is critical. Plumbers, pipefitters, and machinists working with BSPT fittings and pipe assemblies will find this tap a dependable shop-floor tool.

This tap is intended for use in applications requiring British Standard Pipe Taper threads, commonly encountered in fluid system assemblies, hydraulic fittings, and pipe connections that follow BSP standards rather than NPT. The bottoming chamfer allows threading closer to the bottom of a blind hole, making it suitable for tight-tolerance installations where thread engagement depth matters. It is appropriate for use in both production and maintenance environments where BSPT threaded ports or fittings must be tapped or rethreaded.

Key Features

• 1/2-14 BSPT thread size with right-hand thread direction
• Bottoming chamfer for threading near the base of blind holes
• 4-flute straight flute geometry for controlled chip flow
• High-speed steel (HSS) construction for durability across common metals
• Bright, uncoated finish suitable for use with standard cutting fluids
• Shank diameter of 0.7874 inches with a square drive size of 0.515 inches for standard tap wrenches and holders

Compatibility

Designed for cutting 1/2-14 BSPT internal threads in materials compatible with HSS tooling. Fits standard tap wrenches and machine holders accepting a 0.7874-inch shank diameter.

Installation Notes

This tap should be installed by a qualified machinist, pipefitter, or plumber with experience in pipe thread tapping. Always secure the workpiece and use appropriate cutting fluid to extend tool life and improve thread quality. Ensure the pilot hole is drilled to the correct tap drill diameter for 1/2-14 BSPT threads before beginning the tapping operation. Do not force the tap; back off periodically to break chips and prevent tap breakage.
