The UNC A-Spiral Point threading tap from OSG is designed for precise through-hole threading, delivering dependable results for machinists and engineers who demand accuracy and durability in UNC applications.

• Thread Type: UNC A (Unified National Coarse) with a spiral point for efficient, plug-style threading and positive chip evacuation
• Material: Powder metal body for enhanced durability and wear resistance in demanding work environments
• Coating: TiCN coating increases heat resistance, extending tool life and maintaining cutting performance
• Direction: Right-hand threading, suitable for standard UNC through-hole applications
• Size: 7/16" x 14 UNC, optimized for through-hole tap operations
• Through-Hole Design: Specifically engineered for through-hole tapping with efficient chip removal and reduced friction
• DIN Standard: DIN2184-1 compatible geometry and shank design for reliable seating and alignment
• Performance: Supports higher cutting speeds, clean thread finish, and consistent threading results across a range of materials

This tap combines a robust powder metal core with a TiCN coating to deliver long tool life, steady performance, and a high-quality thread finish in through-hole assemblies. Its spiral point geometry promotes quick chip clearance, which helps reduce tapping time and minimizes the risk of built-up material in the threads. Ideal for production environments and reliable repairs alike, it’s a trusted choice for creating durable UNC threads that you can depend on.
