Carmex Thread Turning Internal Insert is a versatile tool for internal threading on standard UN thread profiles. Designed for right-hand applications, it works with UNC, UNF, UNEF, and UNS threads to cover a wide range of jobs with a single insert.

These laydown triangular inserts are built for reliability across basic to demanding tasks, delivering consistent start-to-finish thread quality while helping you minimize setup time and tool changes on busy shop floors.

  • Broad UN thread compatibility: Works with UNC, UNF, UNEF, and UNS right-hand threads, letting you tackle most internal threading jobs with one insert and reducing tool changes.
  • Laydown triangular geometry for stable cutting: The triangular laydown design provides solid support, improved chip control, and smoother thread profiles, even in deep or interrupted cuts.
  • Reliable performance across a wide range of applications: Delivers consistent thread quality across basic to demanding tasks, helping you maintain tight tolerances and predictable outcomes.

By consolidating multiple UN thread standards into a single insert, this tool speeds up setups, reduces downtime, and helps you consistently achieve accurate, smooth internal threads across batches. It’s a practical, long-term addition to any turning operation that handles UNC, UNF, UNEF, or UNS profiles on right-hand threads.
