Value Collection JY79772570 Bsp Pipe Tap 1-11 5 Flute Hss

Product Description

The VALUE COLLECTION JY79772570 is a straight-flute British Standard Pipe tap designed to cut 1-11 G(BSP) internal threads in metal workpieces. Built from high-speed steel (HSS) with a bright, uncoated finish, this tap delivers consistent thread geometry in ferrous and non-ferrous materials. The plug chamfer style provides a gradual thread lead-in, making it well-suited for through-holes and moderately deep blind holes. At 3.75 inches overall length with a 0.7874-inch shank diameter and a 0.8430-inch square drive size, the tool is proportioned for use in a standard tap wrench or machine holder. Right-hand cutting direction follows standard BSP thread convention.

This tap is used wherever G(BSP) parallel pipe threads are required — common in hydraulic fittings, pneumatic assemblies, fluid-power manifolds, and plumbing connections that follow British Standard specifications. It is appropriate for job-shop machining, maintenance and repair operations, and production threading on manual or CNC equipment. The 5-flute geometry provides additional cutting edges compared to standard 4-flute designs, which can improve thread finish and tool life in moderate-hardness materials. Applications span industrial maintenance facilities, machine shops, and trade fabrication environments.

Key Features

• G(BSP) 1-11 thread form for British Standard parallel pipe thread applications
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• Plug chamfer with approximately 3-5 lead threads for controlled thread engagement
• 5-flute straight design increases cutting edge count for improved finish and tool stability
• Bright, uncoated finish suitable for use with standard cutting fluids
• Right-hand thread direction; 0.7874-inch shank and 0.8430-inch square for standard drive compatibility

Compatibility

Designed for cutting 1-11 G(BSP) parallel pipe threads in through-holes and suitable blind holes; fits standard tap wrenches and machine holders accepting a 0.7874-inch round shank with a 0.8430-inch square drive.

Installation Notes

Threading operations should be performed by a machinist or qualified trade technician following standard tapping procedures. Secure the workpiece fully before beginning and use an appropriate cutting fluid to reduce heat and extend tool life. For machine tapping, verify spindle speed is matched to the material and tap diameter per standard feeds-and-speeds references. Inspect the tap for wear or chipping before each use; a damaged tap should not be used, as it can seize in the workpiece.
