The OSG UNC A-Spiral Point threading tap is engineered for precision through-hole threading in UNC applications. Built for professional shops, it combines a powder-metal body with a TiCN coating to deliver fast cutting, clean finishes, and long tool life.

• Thread form: UNC A-Spiral Point design enables efficient chip evacuation and reliable through-hole threads.
• Material: Powder-metal construction delivers enhanced durability and wear resistance under demanding cutting conditions.
• Coating: TiCN coating provides elevated heat resistance and extended tool life in high-speed operations.
• Size / pitch: 1/2-13 UNC per DIN2184-1, for standard coarse threading in through-holes.
• Direction: Right-hand threading, suitable for most common production setups.
• Application: Optimized for through-hole tapping to achieve consistent thread quality.

With this tap, you’ll experience faster material removal, cleaner threads, and greater process stability. The spiral point pushes chips forward, reducing clogging and tool wear, while the TiCN coating stands up to higher cutting speeds and heat. The powder-metal core provides toughness without sacrificing precision, making it a reliable choice for manufacturing, automotive, and general metalworking tasks that require durable, accurate UNC threads.
