Value Collection JY79772703 Bspt Pipe Tap 1/8-28

Product Description

The VALUE COLLECTION JY79772703 is a 1/8-28 BSPT straight-flute pipe tap designed for cutting British Standard Pipe Taper threads in ferrous and non-ferrous materials. Manufactured from high-speed steel (HSS) with a bright uncoated finish, this tap delivers reliable thread-cutting performance in production and maintenance environments. The bottoming chamfer allows threading close to the bottom of a blind hole, making it suitable for tight-clearance fittings. With 4 straight flutes and a right-hand thread direction, it is a direct-application tool for machinists, pipefitters, and maintenance technicians working with BSPT-standard pipe connections.

This tap is used when creating internal 1/8-28 BSPT threads in pipe fittings, manifolds, hydraulic blocks, and fluid-system housings that follow British Standard Pipe Taper specifications. The bottoming chamfer style is selected when thread engagement must extend to the full depth of a shallow or blind hole. Typical applications include industrial maintenance, fluid power, and instrumentation work where BSPT connections are specified. It is not intended for Unified National or NPT thread forms.

Key Features

• 1/8-28 BSPT thread form for British Standard Pipe Taper applications
• Bottoming chamfer for threading to near-full depth in blind holes
• 4 straight flutes with regular hook for controlled chip formation
• High-speed steel construction for durability across a range of workpiece materials
• Bright uncoated finish suitable for use with cutting fluids
• Right-hand thread direction, standard orientation

Compatibility

Designed for cutting internal 1/8-28 BSPT threads per British Standard Pipe Taper specifications. Compatible with standard tap wrenches and holders sized for a 0.7874-inch shank diameter and a 0.3280-inch square drive.

Installation Notes

This tap is installed by a machinist or pipefitter using a calibrated tap wrench or machine tool holder. The workpiece should be secured and the correct pilot hole diameter for 1/8-28 BSPT threads must be drilled before tapping. Apply an appropriate cutting fluid throughout the operation to reduce heat and extend tool life. Do not force the tap if resistance increases unexpectedly — back off to clear chips and inspect the hole.
