The OSG UNC A-Spiral Point Threading Tap is a right-hand, through-hole tap engineered for reliable Unified National Coarse threading. Built for precision and durability, it’s ideal for production environments that demand fast, clean threads in through-holes.

• Thread type: UNC A (Unified National Coarse) threading tap designed for through-hole applications.
• Point style: Spiral point for efficient chip evacuation and smooth entry in through-holes.
• Material: Powder metal construction delivers enhanced durability and wear resistance in demanding use.
• Coating: TiCN coating increases heat resistance, helping maintain sharpness and extend tool life under heavy cutting.
• Through holes: Specifically optimized for clean, consistent threading in through-holes.
• Shank and size: Right-hand tap, No. 3 size with a 48 mm length for precise, scalable threading runs.
• Standard: DIN 2184-1 compliance to ensure compatibility with established UNC threading specifications.
• Performance: Designed for high cutting speeds, excellent finish, and dependable threading results across a variety of base materials.

This tap is built to deliver consistent threads where reliability matters most—production lines, assemblies that require through-hole fasteners, and applications that benefit from efficient chip control and extended tool life. The combination of powder metal toughness and TiCN coating means fewer tool changes and sustained performance, even under demanding threading workloads.
