The OSG UNC A-Spiral Flute Threading Tap is a high-performance solution for tapping Unified National Course threads in blind holes. Designed for machinists and production environments, it blends durability with precise chip control to deliver clean, accurate threads.

• UNC A-Spiral Flute design: Spiral flutes provide efficient chip removal in blind-hole tapping, helping prevent clogging and promoting smooth, stable cutting.
• Powder metal body: Robust construction offers enhanced toughness, wear resistance, and strength for demanding tapping tasks.
• TiCN coating: Hardness and reduced friction extend tool life and improve cutting performance in repetitive, high-speed applications.
• Right-hand thread: Standard orientation for most UNC threading operations, ensuring compatibility with common tooling setups.
• Size: 7/16 x 14, suitable for mid-range UNC fastener threads common in many assemblies.
• DIN2184-1 compliance: Built to DIN2184-1 specifications for reliable interchangeability in professional shops.
• Application focus: Specifically engineered for blind holes, where effective chip evacuation and thread quality matter most.

This tap supports high-speed, high-precision tapping workflows, delivering repeatable results with durable wear resistance and smoother thread production. Its TiCN coating and powder-metal construction work together to minimize downtime, extend tool life, and produce clean, consistent UNC threads in challenging blind-hole applications.
