Hertel R867371-S Bsp Pipe Tap 1-11 G Plug 5 Flute Hss

Product Description

The HERTEL R867371-S is a British Standard Pipe tap designed for cutting G(BSP) internal pipe threads in metal workpieces. This plug-chamfer tap features 5 flutes and is manufactured from high speed steel with a bright finish, making it suited for general-purpose threading in a range of ferrous and non-ferrous materials. With a thread size of 1-11 and an overall length of 3.75 inches, it fits standard tap wrenches and machine setups used in plumbing fabrication, industrial maintenance, and mechanical assembly shops. Machinists, pipefitters, and maintenance technicians are the primary users of this tool.

This tap is used when cutting G(BSP) parallel pipe threads, which are common in British Standard plumbing fittings, hydraulic systems, and pneumatic assemblies. The plug chamfer style provides a moderate lead-in, typically 3 to 5 threads of taper, making it suitable for through-holes and moderately deep blind holes. It is well matched to manual tapping operations as well as light-duty machine tapping in shop and field environments where BSP-threaded connections are specified.

Key Features

• G(BSP) thread standard for British Standard Pipe parallel thread applications
• 1-11 thread size with 1.75-inch thread length for adequate thread engagement
• Plug chamfer provides moderate lead-in suitable for through-holes and most blind-hole applications
• 5-flute design promotes chip clearance and consistent thread form
• High speed steel construction offers durability across a range of workpiece materials
• Bright finish with regular hook geometry for general-purpose threading operations

Compatibility

Designed for use in applications requiring G(BSP) parallel pipe thread tapping at 1-11 thread specification. Compatible with standard tap wrenches and machine tap holders sized for the shank dimensions of this tool.

Installation Notes

This tap should be installed and operated by a qualified machinist or pipefitter familiar with thread-cutting procedures and appropriate cutting fluids for the workpiece material. Always secure the workpiece fully before beginning tapping operations and ensure the tap is started square to the hole to avoid thread damage or tap breakage. Do not force the tap against the bottom of a blind hole without confirming adequate chip clearance. Follow shop safety practices and applicable workplace codes when operating cutting tools.
