The OSG UNF A-Spiral Point threading tap is engineered for precise through-hole UNF threading, delivering durable, reliable performance for machining shops that demand clean, accurate threads. Built with a powder-metal body and TiCN coating, this right-hand tap combines toughness with exceptional wear resistance for demanding applications.

• Thread form and geometry: UNF thread with A-Spiral Point geometry designed to push chips forward and improve chip control in through-holes.
• Material: Powder-metal construction for enhanced toughness, wear resistance, and heat tolerance compared to traditional steels.
• Coating: Multilayer TiCN coating reduces friction and extends tool life under high-speed cutting conditions.
• Through-hole DIN 2184-1: Specifically designed to meet DIN2184-1 through-hole specifications for reliable threading quality.
• Shank and drive: Right-hand threading compatible with standard machining setups for straightforward integration into existing processes.
• Size: 1 x 8 tapping size, suitable for UNF through-hole applications.

This tap helps you achieve consistent, tight UNF threads with minimal burrs and longer tool life. The spiral-point design promotes efficient chip removal, reducing the risk of clogging in through-holes and supporting higher feed rates. The combination of powder-metal construction and TiCN coating delivers durable performance across a range of materials, making it well suited for high-volume production and precision projects where through-hole UNF threads are required.
