The OSG UNC A-Spiral Point Threading Tap is a precision tool designed for through-hole UNC threading. Built for metalworking professionals and production environments, it delivers reliable performance with clean, accurate threads.

• Thread type: UNC A (Unified National Coarse) with spiral-point geometry for efficient through-hole tapping
• Material & coating: Powder-metal body with TiCN coating for enhanced wear resistance and heat tolerance
• Cutting direction: Right-hand thread to suit common machining setups
• Through-hole design: Optimized for through-hole applications with effective chip evacuation
• Standard: DIN 2184-1 compatible for consistent tooling integration
• Size & length: No. 2 size x 56 mm overall length

With TiCN coating, the tap maintains cutting efficiency under higher speeds and feeds, extending tool life and reducing downtime. The spiral-point design directs chips away from the cutting zone, promoting smoother cuts and faster cycle times. The powder-metal construction provides durable performance without compromising precision, making it well-suited for a variety of materials and production demands. This tap is an ideal choice for shops needing dependable UNC threading with a consistent finish on through-hole components.
