The Carmex Thread Turning Internal Insert – NPTF, Right Hand, 16IR18NPTFBMA is a high-performance internal threading insert designed for precision work on lathes and turning centers. Its laidown triangular geometry provides stable engagement, clean thread profiles, and long tool life across a wide range of thread standards.

Designed for versatility, this insert handles everything from common, lightweight threads to more demanding applications, helping shops reduce tool changes and maintain consistent results on mixed jobs.

  • Broad thread compatibility: Covers a wide range of thread standards, reducing the need for multiple tools and speeding up setups on diverse jobs.
  • Durable laydown triangular geometry: The laydown shape distributes cutting forces evenly, improves chip control, and extends tool life in challenging materials and deeper thread depths.
  • Easy mounting for reliable results: Right-hand orientation and standardized seating simplify integration into existing toolholders, delivering consistent threads with minimal rework.

This insert helps you streamline threading operations: fewer tool changes, reduced downtime, and more consistent thread quality across parts. By delivering stable performance from basic to demanding applications, it supports higher throughput, tighter tolerances, and an improved overall workflow in your shop.
