The OSG Threading Tap is a right-hand, spiral-point tool crafted for cutting British Standard Whitworth (BSW) threads in through holes. Built with a powder-metal substrate and a TiCN coating, it delivers durable performance and reliable thread quality in a variety of materials.

• Thread type: BSW A-Spiral Point design to aid rapid chip evacuation and smooth alignment in through-holes.
• Material: Powder metal construction for enhanced wear and heat resistance across demanding tapping tasks.
• Coating: TiCN coating to extend tool life and improve cutting performance at higher speeds.
• Holes compatibility: Optimized for through-hole tapping with DIN2184-1 specification for consistent thread form.
• Size: 3/8 x 16 standard for Whitworth applications.
• Direction: Right-hand threading, suitable for common clockwise tapping operations.
• Chip evacuation: Spiral point geometry directs chips forward, reducing chip packing and improving finish.
• Applications: Ideal for precision BSW thread creation in metalwork, repair, and maintenance projects dealing with Whitworth fasteners.

This tap is designed to deliver clean, accurately formed threads with minimal deflection and consistent results, even at higher feed rates. The combination of powder-metal substrate and TiCN coating supports longer tool life, better wear resistance, and steadier performance when tapping through holes in steel, cast iron, and other common machine shop materials.
