The OSG Threading Tap BSW A-Spiral Point is a precision through-hole tapping tool designed for British Standard Whitworth threads. Built for professional machinists, it combines robust powder-metal construction with a TiCN coating to deliver clean, accurate threads in demanding through-hole applications.
- Size & Thread: 5/16 x 18 BSW through-holes for standard Whitworth threading, optimized for through-hole tapping.
- A-Spiral Point Design: Spiral-point geometry pushes chips ahead of the tap, promoting smooth cutting and reducing clogging during tapping.
- Material: Powder-metal substrate that delivers enhanced wear resistance and toughness under high-speed cutting conditions.
- Coating: TiCN coating lowers friction and improves heat resistance, extending tool life and maintaining sharpness between regrinds.
- Through-Hole Compatibility: Specifically engineered for through-hole applications per DIN2184-1, ensuring reliable engagement and consistent thread quality.
- Drive Direction: Right-hand thread configuration, suitable for the majority of standard tapping tasks.
- Construction & Finish: Precisely ground flute geometry and robust build provide stable performance across materials commonly encountered in metalworking.
This tap is designed to deliver precise, clean threads with minimal burr and reliable repeatability, even at higher tapping speeds. The combination of powder-metal substrate and TiCN coating helps resist wear and heat, making it well-suited for a range of materials encountered in fabrication and repair work. Ideal for workshops that require consistent thread quality in through-holes without sacrificing tool life or performance.
