  • Size & Thread: 7/32" cutting size with 28 threads per inch, BSF (British Standard Fine) thread for precise fit in blind holes.
  • Material: High-Speed Steel with cobalt (HSS-E) for increased hardness and wear resistance.
  • Coating: Steam oxide coating provides durable wear protection and heat resistance.
  • Flute Design: Spiral flutes optimize chip evacuation, reducing binding in blind-hole threads.
  • Application: Specifically designed for blind hole threading, delivering clean, accurate BSF threads.
  • Brand & Technology: Part of OSG’s precision threading range, built for reliability and long tool life.

With this combination, you’ll achieve consistent, accurate BSF threads in demanding materials while extending tool life and minimizing downtime. The spiral flute and HSS-E cobalt chemistry work together to handle heat and abrasion, helping you complete critical tapping tasks with confidence.
