The OSG Threading Tap BA A-Spiral Point is engineered for precise tapping of British Association (BA) threads in through-holes. Built for machinists and precision assemblers, it delivers fast, clean threads with reliable tool life.

• Thread Type: BA (British Association) threads designed for through-hole tapping
• A-Spiral Point Design: Spiral-point geometry pushes chips forward to prevent clogging and improve chip evacuation
• Material: Powder-metal core delivering enhanced durability, heat resistance, and wear resistance
• Coating: TiCN coating extends tool life and improves cutting efficiency
• Direction: Right-hand threading for standard BA applications
• Through-Hole Optimization: Specifically engineered for tapping through-holes with consistent performance
• Size designation: 11BA for precise, small-diameter BA threading

With its combination of a powder-metal core and TiCN coating, this tap is built to withstand demanding production environments while maintaining tight tolerances. The spiral-point geometry reduces chip buildup, enabling faster threading cycles and less downtime due to tool wear or clogging. It’s a reliable choice for high-speed BA-threading tasks across a range of common materials, helping you achieve repeatable results in electronics housings, instrumentation components, and other precision assemblies where BA threads are standard.
