The OSG BSF Spiral Point Threading Tap in 7/32 x 28 is designed for through-hole BSF tapping, delivering precise thread form and reliable performance in metal parts. Built with HSS-E and a Steam Oxide coating, it stands up to demanding machining tasks with extended tool life.

• Material: HSS-E (high-speed steel with cobalt) for increased hardness and heat resistance.
• Coating: Steam Oxide finish to enhance wear resistance and durability in tough cutting conditions.
• Thread type: BSF (British Standard Fine) spiral point geometry for accurate threads and efficient chip evacuation.
• Design: Spiral point pushes chips forward, reducing clogging in through-hole applications and improving cycle times.
• Through-hole compatibility: Optimized for through-hole tapping, delivering consistent thread quality from start to finish.
• Size: 7/32 x 28, providing a precise BSF thread pitch for compatible components.

With the OSG BSF Spiral Point Threading Tap, you can achieve clean, accurate BSF threads in through-holes while benefiting from extended tool life and better heat resistance. The cobalt-infused core handles tougher materials and higher cutting speeds, making it suitable for automotive brackets, machinery frames, and fabrications requiring dependable BSF threads. The combination of spiral point geometry and steam oxide coating helps minimize chatter and wear, supporting repeatable results across production runs and repairs alike.
