Carmex External Right Hand UN Unified Thread Turning Insert 16mm / 18 TPI / 16 ER 18 UN BMA

External Thread Turning Insert – UN Full Profile 60°

The UN Full Profile External Thread Turning Insert is designed for high-precision threading of Unified thread forms (UNC, UNF, UNEF, UNS). With a 60° profile and 18 TPI pitch, this insert forms the full thread geometry—crest, root, and flanks—in a single operation, delivering accuracy and strength in external threading applications.

Manufactured from robust BMA-grade carbide, this insert provides a strong balance of wear resistance and toughness, making it suitable for machining steel and alloy components. The refined X and Y dimensions contribute to smooth chip evacuation, stable cutting action, and long tool life in high-volume or high-precision environments.
