Engineered for precision threading in blind holes, the OSG BSW Spiral Flute Threading Tap delivers clean, accurate threads with extended tool life. Built for professional shops, it combines cobalt-enhanced HSS-E with a durable Steam Oxide coating to withstand demanding tapping tasks.

  • Thread size: BSW 9/16"-12 tapping size for accurate British Standard Whitworth threads in blind holes
  • Flute design: Spiral flute for efficient chip evacuation and reduced binding in deep, blind-hole applications
  • Material: HSS-E (high-speed steel with cobalt) for improved wear resistance and heat tolerance
  • Coating: Steam oxide finish to enhance durability and provide lubricity during tapping
  • Precision and reliability: OSG’s advanced threading technology delivers high-quality, consistent threads and longer tool life

This tap is ideal for production runs and maintenance work where reliable, repeatable performance matters. The spiral flute helps keep chips moving away from the cutting edge, minimizing re-cutting and tool stress in blind-hole situations. The combination of HSS-E and steam-oxide coating supports tougher materials and higher-speed tapping while maintaining accurate thread form and finish.
