The OSG Threading Tap UNC A-Spiral Flute is a high-performance right-hand tap designed for reliable tapping of UNC threads in blind holes. Crafted for demanding machinists, it combines durable powder metal construction with a hard TiCN coating to enhance tool life and cutting efficiency.

• Thread Type: UNC A (Unified National Course) threading for standard coarse-thread applications
• Flute Design: A‑spiral flute for efficient chip evacuation in blind-hole tapping, helping maintain smooth operation
• Material: Powder metal construction for durability, wear resistance, and strength in tough materials
• Coating: TiCN coating to increase surface hardness, reduce friction, and improve cutting performance
• Hand: Right-hand tap suitable for clockwise threading
• Application: Optimized for blind holes, compliant with DIN2184-1 standards
• Size: 3/4 x 10, designed for medium to larger UNC threads in production or precision environments

This tap is engineered to deliver dependable performance across repeated production runs. The combination of powder-metal body and TiCN coating provides a balance of toughness and low friction, while the spiral flute aids chip removal in blind-hole scenarios. Practically, you can expect clean threads, reduced tool wear, and consistent results during high-speed or high-precision tapping tasks.
