The OSG BSP Spiral Point Threading Tap is a precision tapping tool built for through‑hole BSP threading. Designed for machinists and fabrication professionals, it combines durability with reliable performance for demanding tapping tasks.

• Thread type: BSP (British Standard Pipe) spiral point design optimized for efficient through‑hole tapping.
• Material: HSS‑E (high‑speed steel with cobalt) for enhanced heat resistance and extended tool life.
• Coating: Steam oxide coating minimizes friction and provides additional wear and corrosion resistance.
• Size: 1/2" nominal diameter, 14 TPI (1/2 x 14) for BSP thread applications.
• Flute geometry: Spiral point (gun‑type) flute promotes forward chip evacuation, reducing clogging in through holes.
• Applications: Ideal for through‑hole BSP thread tapping in metal fabrication, plumbing, hydraulic, and mechanical assemblies.
• Brand: OSG, a trusted leader in precision threading tools and inserts.

This tap delivers precise BSP threads with consistent quality and longer tool life thanks to its cobalt‑alloy substrate and steam oxide finish. The spiral point design helps push chips out of the hole, enabling faster tapping cycles and minimizing the risk of jammed threads. Ideal for production runs and maintenance tasks that require reliable BSP threading in through‑hole components, it’s a robust choice for professional workshops and job sites alike.
