Meet the OSG Threading Tap UNC A-Spiral Point — a powder-metal, TiCN-coated threading tap designed for through-hole UNC applications. Built for seasoned machinists and production environments, it delivers reliable, precise threads with durable performance.

• Thread Type: UNC A (Unified National Coarse) specification for standard coarse-thread tapping
• Geometry: Spiral Point design to efficiently push chips forward in through-holes and improve tapping speed
• Material: Powder Metal construction for enhanced toughness and wear resistance
• Coating: TiCN coating provides improved heat resistance and extended tool life under demanding cuts
• Direction: Right-Hand thread for common rotation and compatibility with typical machines
• Through-Hole Optimization: Specifically suited for through-holes, promoting cleaner threads and faster chip evacuation
• Size: 3/8 x 16 (8.0 mm nominal diameter with 16 threads per inch), a common UNC coarse size
• Standard: DIN2184-1 compatibility ensures consistent geometry and interchangeability
• Material Versatility: Suitable for a variety of metals, enabling broad application across projects

This tap is engineered to deliver dependable, high-quality threads with minimal deflection and excellent finish. The TiCN coating reduces wear in high-speed cuts, while the spiral point geometry keeps chips moving out of the hole for consistent results. With its durable powder-metal core and DIN2184-1 standards, it’s a reliable choice for production tapping, maintenance, and repair work where 3/8-16 UNC threads are required.
