Value Collection JY79772562 Bsp Pipe Tap 1-1/4-11 Plug 5 Flute Hss

Product Description

The VALUE COLLECTION JY79772562 is a straight-flute British Standard Pipe tap designed to cut internal G(BSP) threads in metal workpieces. Sized at 1-1/4-11 — meaning a 1-1/4-inch nominal diameter with 11 threads per inch — this tap features a plug chamfer for general-purpose through-hole and blind-hole threading. Constructed from high-speed steel (HSS) with a bright, uncoated finish, it delivers reliable cutting performance across a range of ferrous and non-ferrous materials. The 5-flute design provides additional cutting edges for a cleaner thread form, making it a practical choice for machinists and pipefitters working to BSP thread standards.

This tap is suited for threading pipe fittings, manifolds, hydraulic blocks, and other components that require G(BSP) internal threads. The plug chamfer — typically 3 to 5 threads of taper — allows the tap to start easily in a pre-drilled hole and is the most common choice for general shop use. It is appropriate for both manual tapping with a tap wrench and machine tapping on a drill press or CNC setup where rigid tapping is supported. Applications span industrial maintenance, plumbing fabrication, and fluid-power component repair.

Key Features

• 1-1/4-11 G(BSP) thread form for British Standard Pipe compatibility
• Plug chamfer for easy starting in through-holes and moderate-depth blind holes
• 5-flute straight-flute geometry for clean thread cutting and added cutting edges
• High-speed steel (HSS) construction for durability across a wide range of materials
• Bright, uncoated finish — suitable for use with cutting fluid on most common metals
• Right-hand thread direction, standard for BSP pipe thread applications

Compatibility

Designed for cutting 1-1/4-11 G(BSP) internal threads in pre-drilled holes sized to the appropriate tap drill diameter for British Standard Pipe thread specifications.

Installation Notes

Tapping operations should be performed by a qualified machinist or pipefitter using a properly sized tap wrench or rigid tapping setup. Always use an appropriate cutting fluid for the workpiece material to reduce friction and extend tap life. Ensure the tap is started perpendicular to the workpiece surface to avoid cross-threading or tap breakage. Back the tap off periodically to break chips, especially in blind-hole applications.
