The OSG Threading Tap, BSW A-Spiral Point, is a right-hand through-hole tap engineered for accurate British Standard Whitworth threads. Designed for reliable production and repair work, it delivers clean, consistent threads in through-holes with every cut.

• Thread size and standard: 1/8 in diameter, 40 TPI BSW, engineered for through-hole DIN 2184-1 tapping.
• A-Spiral Point geometry: Improves chip evacuation and enables fast, smooth thread start-up.
• Material: Powder Metal substrate for enhanced wear and heat resistance under demanding machining conditions.
• Coating: TiCN coating reduces wear and lowers friction for longer tool life and better cutting performance.
• Direction: Right-hand threading suitable for clockwise tapping operations.
• Application: Optimized for through-hole tapping across a range of common metals with consistent results.

This tap helps you achieve precise, clean BSW threads efficiently, with reduced downtime and fewer reworks. The combination of powder metal durability, TiCN-coated cutting edges, and spiral-point design ensures reliable performance in production runs and maintenance work alike. Ideal for shops that handle standard through-hole fastener threads and require dependable tooling that maintains edge precision over multiple uses.
