Value Collection JY79772661 Bspt Pipe Tap 1-1/4-11

Product Description

The VALUE COLLECTION JY79772661 is a straight-flute British Standard Pipe Tap designed to cut 1-1/4-11 BSPT internal threads in metal workpieces. Built from high-speed steel (HSS) with a bright, uncoated finish, this tap delivers consistent thread geometry in both production and maintenance environments. The bottoming chamfer allows threading to run close to the bottom of a blind hole, making it suited for tight-tolerance pipe fitting applications. With 5 flutes and a right-hand thread direction, this tap is handled by machinists, pipefitters, and maintenance technicians working with BSPT-threaded components.

This tap is used wherever British Standard Pipe Taper threads are required, most commonly in fluid, hydraulic, and pneumatic systems that follow BSP thread standards. Typical applications include cutting threads into pipe fittings, manifold blocks, valve bodies, and equipment housings that accept BSPT-threaded connectors. The bottoming chamfer design is especially useful in blind-hole situations where full thread depth near the bottom of the bore is required. It is appropriate for use in both light industrial maintenance settings and dedicated machine shop operations.

Key Features

• 1-1/4-11 BSPT thread size for British Standard Pipe Taper applications
• Bottoming chamfer for threading close to the bottom of blind holes
• 5-flute straight-flute design for stable cutting and chip control
• High-speed steel (HSS) construction for durability in metal threading
• Bright, uncoated finish suitable for use with standard cutting fluids
• Right-hand thread direction, standard for BSPT applications

Compatibility

Designed for cutting 1-1/4-11 BSPT internal threads in ferrous and non-ferrous metals; compatible with standard tap holders and machine spindles accepting a 0.9843-inch shank diameter.

Installation Notes

This tap is installed and operated by machinists or qualified maintenance technicians using a tap wrench, tapping head, or CNC machine with appropriate tap holder. Before tapping, ensure the workpiece is securely fixtured and the correct pilot hole diameter for 1-1/4-11 BSPT threads has been drilled. Apply cutting fluid throughout the tapping operation to reduce heat and extend tool life. Do not force or back-drive the tap without periodically clearing chips, especially in blind-hole applications.
