The OSG BSW Spiral Point Threading Tap is a high-performance tool designed for precise through-hole threading in British Standard Whitworth (BSW) sizes. Built for professional machinists and job shops, it delivers clean, accurate threads with long tool life under demanding tapping tasks.
- Size & Thread: 9/16" diameter, 12 TPI BSW thread for through-hole applications
- Material: HSS-E (high-speed steel with cobalt) for enhanced heat resistance and durability
- Coating: Steam oxide coating to improve wear resistance and lubricity during tapping
- Design: Spiral point geometry facilitates efficient chip evacuation and forward-plowing action in through-holes
- Application: Optimized for through-hole tapping, delivering consistent thread quality in common machine components
This tap is engineered to maintain form and precision even in tougher materials, reducing cycle time and rework. The cobalt-enriched HSS-E construction stands up to heat generated during tapping, while the steam oxide coating provides protection against wear and corrosion. The spiral point design channels chips away from the thread crest, helping prevent built-up burrs and improving surface finish on each part. Ideal for maintenance, repair, and production environments where reliable through-hole threads are essential.
