The OSG Threading Tap BA A-Spiral Point is a precision tapping tool engineered for British Association (BA) threads in through holes. Its spiral-point design pushes chips forward for cleaner cuts and faster material removal, delivering dependable performance in compact, high-precision applications.

• Thread Type: BA (British Association) threads for accurate, miniature internal threading
• A-Spiral Point Design: Efficient chip evacuation that minimizes clogging and improves cutting consistency
• Material: Powder metal substrate delivering durability, heat resistance, and wear longevity
• Coating: TiCN coating to extend tool life and enhance cutting efficiency
• Through Hole Compatibility: Specifically built for tapping through-hole workpieces
• Drive/Direction: Right-hand threading for standard assembly workflows
• Size: 10BA, suited for fine-pinish BA applications
• Brand: OSG, a recognized name in precision tapping tools

This combination of design, materials, and coating translates to reliable thread formation, reduced chip buildup, and longer tool life in demanding tapping jobs. The TiCN coating lowers friction and heat generation at the cutting edge, while the powder-metal body provides the toughness required for repeated use at higher speeds. Ideal for precision instruments, miniature components, and tight through-hole assemblies where consistent BA threads and clean finishes matter.
