16ER20UNK20 - Carmex Thread Turning External Insert - UN (UNC,UNF,UNEF,UNS) - Right Hand

The Carmex Thread Turning External Insert is a precision cutting insert engineered for external threading on lathes. This laydown triangular insert is compatible with UN thread standards—UNC, UNF, UNEF, and UNS—and is designed for right-hand turning. The 16ER20UNK20 code identifies its size and geometry, helping you match it with standard holders and feeds across a wide range of applications.

• Broad UN-thread compatibility: Enables threading across UNC, UNF, UNEF, and UNS with a single insert, reducing tool changes and increasing productive time.
• Durable laydown triangular geometry: Provides stable cutting action and efficient chip control for clean thread surfaces and longer tool life.
• Right-hand orientation for predictable results: Consistent turning direction with standard tooling setups, helping maintain accuracy and reduce setup errors.

With this insert in your toolkit, you’ll simplify thread turning workflows, cut threads with confidence in a single setup, and maintain consistent dimensional accuracy across basic to demanding applications. Its versatile UN-thread coverage and robust geometry help you minimize downtime, reduce rework, and deliver reliable, repeatable results on every job—from prototype runs to high-volume production.
