The Carmex Spiral Flute UNF Supercut Tap in 9/16 x 18 is a precision threading tool built for machinists, fabricators, and workshops that demand accurate UNF threads in demanding materials. With HSS-E construction and a spiral flute, it’s engineered for durability and efficient chip evacuation during high-speed threading tasks.

• Thread Type & Size: UNF threading tap, 9/16-18, designed for clean, fine-pitched internal threads.
• Flute Design: Spiral flute geometry ensures continuous chip removal and reduces the risk of clogging during deep cuts.
• Material: High-Speed Steel with cobalt content (HSS-E) for improved heat resistance and longer tool life.
• Geometry & Construction: UNF Supercut geometry helps deliver smooth, accurate threads and extended cutting performance.
• Applications: Optimized for challenging materials and high-speed threading operations in UNF applications.

Whether you’re producing tight-tolerance parts or performing on-demand repairs, this tap helps you achieve reliable UNF threads with consistency. The spiral flute reduces chip buildup and heat, enabling faster, smoother threading while preserving thread accuracy. The durable HSS-E composition withstands demanding machining conditions, reducing tool changes and downtime in production environments.
