Carmex Thread Turning Internal Insert - UNJ (UNJC UNJF UNJEF UNJS) - Left Hand - 11IL16UNJBMA

Carmex Thread Turning Internal Insert is a precision cutting insert designed for internal threading on CNC lathes and manual machines. This Left Hand version supports UNJ thread standards (UNJC, UNJF, UNJEF, UNJS) with a versatile geometry that covers a wide range of applications.

Engineered for reliability, its laydown triangular geometry delivers stable engagement, clean chip control, and consistent thread form from basic holes to the most demanding production tasks.

• Broad UNJ compatibility: The insert supports UNJC, UNJF, UNJEF, and UNJS thread standards in a single geometry, reducing tool changes and inventory for shops that run multiple thread types.
• Left-hand threading optimization: Specifically designed for left-hand threads, delivering consistent starts, controlled depth, and reliable form across parts.
• Durable triangular laydown geometry: Precision-ground carbide with a robust cutting edge for long tool life and repeatable, high-quality threads across a range of applications.

This insert helps you streamline internal threading workflows by offering a single, ready-to-use solution for multiple UNJ standards, enabling faster setups and reduced downtime. Its durable carbide construction and geometry maintain thread accuracy and surface finish over many cycles, delivering reliable performance from simple holes to demanding production runs.
