The OSG BA A-Spiral Point Threading Tap is a precise, right-hand tool designed for tapping British Association (BA) threads in through holes. Built for reliability in small-thread applications, it delivers clean, consistent threads in a compact, demanding workspace.

• Size: 9BA
• Thread Type: British Association (BA) threads
• Geometry: A-Spiral Point to push chips forward and improve evacuation
• Material: Powder Metal for enhanced hardness, heat resistance, and wear life
• Coating: TiCN coating to extend tool life and boost cutting efficiency
• Drive/Orientation: Right-Hand threading for standard BA applications
• Hole Type: Designed for tapping BA threads in through holes

With its spiral-point design and durable powder-metal substrate, this tap maintains consistent performance under high-speed threading and challenging materials. The TiCN coating minimizes wear and reduces friction, helping you achieve reliable thread quality, longer service life, and reduced downtime in precision assemblies such as instrumentation, electronics enclosures, and small mechanical components.
