The OSG BA Spiral Flute Threading Tap is a precision tool designed for creating British Association (BA) threads in blind holes with consistent, accurate results. It’s ideal for small-part assembly and maintenance tasks where reliable, repeatable thread formation matters.

• Thread Size: 6BA
• Thread Type: BA (British Association) thread for compact, delicate assemblies
• Flute Design: Spiral flute geometry engineered for efficient chip evacuation in blind holes
• Material: Powder metal body delivering durable wear resistance
• Coating: TiCN coating reduces friction and enhances heat resistance for longer tool life
• Cutting Direction: Right-hand (clockwise) threading for standard BA tapping applications
• Application: Specifically optimized for tapping BA threads in blind-hole scenarios

The combination of spiral flutes and TiCN-coated powder metal construction means cleaner thread formation, fewer breakages, and extended tool life even when tapping into tougher or deeper blind holes. The TiCN coating lowers surface friction, allowing higher cutting speeds without sacrificing precision, while the powder metal core provides durability for repeated uses in production or maintenance environments. This tap is well-suited for precision enclosures, instrument panels, and small hardware assemblies where BA threads are required but access is limited by a blind hole.
