Value Collection JY79772604 Bsp Pipe Tap 1/8-28 Plug 4 Flute

Product Description

The VALUE COLLECTION JY79772604 is a straight-flute British Standard Pipe tap designed for cutting 1/8-28 G(BSP) internal threads in ferrous and non-ferrous materials. Built from high speed steel (HSS) with a bright, uncoated finish, it delivers reliable cutting performance in hand-tapping and low-speed machine-tapping operations. The plug chamfer configuration — with 3 to 5 chamfered threads — provides a balance between starting ease and thread engagement, making it a practical choice for through-hole and shallow blind-hole pipe thread applications. At 2.125 inches overall length and a 0.8661-inch shank diameter, this tap fits standard tap wrenches and holders sized for its shank.

This tap is intended for cutting G(BSP) straight pipe threads commonly found in hydraulic fittings, pneumatic systems, fluid-power components, and plumbing assemblies that follow British Standard specifications. It is suited for use in maintenance, repair, and fabrication environments where BSP-threaded connections must be tapped into new or existing components. Machinists, pipefitters, and millwrights typically use this tap when working with imported equipment or instrumentation ports that require BSP rather than NPT threads.

Key Features

• 1/8-28 G(BSP) thread form for British Standard straight pipe thread applications
• High speed steel construction for durability across a range of workpiece materials
• Plug chamfer for versatile use in through-holes and shallow blind holes
• 4 straight flutes provide chip clearance in standard cutting conditions
• Bright, uncoated finish suitable for use with cutting oils and standard tapping fluids
• Right-hand thread direction; regular hook geometry for general-purpose cutting

Compatibility

Designed for cutting 1/8-28 G(BSP) straight pipe threads in components requiring British Standard Pipe thread form. Fits standard tap wrenches and machine holders accepting a 0.8661-inch round shank with a 0.3280-inch square drive.

Installation Notes

Secure the workpiece firmly before tapping and ensure the starting hole is drilled to the correct tap-drill diameter for 1/8-28 G(BSP) thread. Apply an appropriate cutting fluid or tapping oil throughout the operation to extend tool life and improve thread quality. Use a calibrated tap wrench or low-speed machine spindle and back off periodically to break chips. Do not force the tap if resistance increases suddenly — back out, clear chips, and re-lubricate before continuing.
