The OSG BA A-Spiral Point Threading Tap is engineered for precise tapping of British Association threads in through holes, delivering reliable performance for both professional shops and precision hobbyists.

• Threading standard: British Association (BA) threads, 7BA size
• Geometry: A-Spiral Point design to push chips forward and maintain consistent cutting action
• Material: Powder metal construction for strong wear resistance and long tool life
• Coating: TiCN coating to reduce friction, extend tool life, and improve cutting efficiency
• Direction: Right-hand threading for standard through-hole operations
• Through-hole suitability: Specifically optimized for tapping through holes with clean, accurate thread formation
• Application benefits: Designed for high-speed threading with robust heat resistance in demanding materials
• Brand: OSG, a trusted name in high-performance tapping solutions

This tap combines a durable powder-metal body with a TiCN coating to deliver steady performance under load. The spiral point helps evacuate chips efficiently, reducing clogging and improving thread quality in through-hole applications. Ideal for metalworking setups where BA threads are required, the 7BA size provides precise, consistent threads with reduced insert wear and longer tool life, even at higher cutting speeds.
