Carmex Thread Turning Internal Insert is a metric, left-hand, laydown triangular cutting insert designed for precise internal threading. It’s ideal for engineers, machinists, and shops that work with metric threads, enabling reliable performance across a wide range of applications—from routine maintenance to production runs.

- Broad metric and left-hand compatibility: Designed to cover a wide range of metric thread standards and left-hand threads, reducing the need for multiple tools and speeding up setups.
- Three-edge laydown geometry for longer life: The triangular, laydown design allows you to index to fresh edges, extending tool life and lowering replacement frequency in busy environments.
- Consistent internal thread performance: Precise geometry delivers uniform thread form and smooth surface finish across standard and demanding applications, helping you meet tight tolerances with less rework.
By choosing this insert, you streamline internal threading work, reduce downtime from tool changes, and achieve reliable, repeatable thread quality across various metric left-hand tasks. Its robust design supports both routine maintenance and production runs, delivering predictable results and an efficient workflow.
