The OSG BSP Spiral Point Threading Tap is a high-performance tool built for professionals who need fast, accurate BSP threads in through-hole components. Crafted from HSS-E with cobalt and finished with a Steam Oxide coating, it blends durability with reliable cutting performance for demanding machining tasks.

• Material: HSS-E (high-speed steel with cobalt) for exceptional hardness and heat resistance in tough tapping applications.
• Coating: Steam oxide coating enhances wear resistance and lubricity, helping extend tool life during continuous production.
• Threading geometry: BSP Spiral Point design directs chips forward, enabling efficient chip evacuation in through-holes and reducing the risk of clogging.
• Application: Specifically engineered for BSP threading in through-hole work, delivering precise thread profiles for plumbing, hydraulic, and mechanical assemblies.
• Size: 1 x 11, aligning with common BSP through-hole specifications for reliable compatibility.
• Manufacturer advantage: Part of OSG’s advanced threading technology lineup, designed to maintain consistent pitch accuracy and extended tool life in production environments.

This tap enables quick, clean BSP thread generation with minimal rework. The spiral-point geometry keeps through-holes clear, reducing downtime in production runs. The HSS-E cobalt composition and steam-oxide finish resist heat and wear, helping you achieve more holes per tool and consistent thread quality across batches. Ideal for plumbing, pneumatic, and hydraulic components where reliable BSP connections matter.
