The OSG Threading Tap BSW A-Spiral Point is a high-performance tapping tool designed to cut British Standard Whitworth threads in through-holes with precision and efficiency. Built for machinists and production environments, it combines durable powder-metal construction with a TiCN coating to deliver reliable results at speed.

• Size and thread: 3/16 in diameter, 24 TPI (BSW); DIN2184-1 through-hole design.
• A-Spiral Point geometry: Pushes chips forward for smooth, efficient tapping in through-holes.
• Material: Powder metal body delivering excellent wear resistance and heat tolerance for long life.
• Coating: TiCN coating reduces friction and extends tool life for high-speed cutting.
• Through-hole suitability: Specifically optimized for through-hole tapping to produce consistent thread depth and profile.
• Right-hand tapping: Standard orientation for most BSW applications.

When you pair this tap with a quality tapping setup, you’ll achieve precise, clean threads with minimal rework. The spiral point design helps keep chips moving forward, reducing the risk of tool clogging and thread defects. The TiCN coating withstands higher speeds and tougher materials, while the powder-metal core provides dependable durability for production runs. Ideal for fabrication, maintenance, and repair tasks that require reliable BSW threads in through-holes.
