Description
The Carmex Thread Turning Internal Insert - UN (UNC, UNF, UNEF, UNS) Left Hand (22IL5UNBMA) is a precision cutting insert designed to form internal threads to the common UNC/UN standards. This left-hand variant is suited for a wide range of internal threading tasks, making it a versatile choice for machinists and manufacturers.
These high-quality laydown triangular inserts can provide a solution for the majority of the thread standards available today and they can handle a wide range of applications: From the basic, to the most demanding ones.
- Broad thread-standard compatibility: Covers UNC, UNF, UNEF, and UNS with a single insert family, simplifying stocking and reducing tool changes in mixed-thread environments.
- Laydown triangular geometry for stable cutting: The triangular laydown form provides robust support and predictable chip control, delivering consistent internal threads across a variety of hole sizes.
- Left-hand orientation for versatile threading: The left-hand configuration enables reliable internal threading on left-handed builds and specific machining setups, expanding your tooling options without swapping inserts.
Designed for reliability and versatility, this insert helps you complete internal threads with clean finishes, reduces downtime by staying in use across multiple thread standards, and supports a smooth workflow from setup to production—whether you’re tackling basic tasks or demanding threading jobs.
