Carmex External Right Hand UN Unified Thread Turning Insert 14 TPI / 16 ER 14 UN P25C

External Thread Turning Insert – UN Full Profile 60°

The UN Full Profile External Thread Turning Insert is designed for cutting Unified thread forms (UNC, UNF, UNEF, UNS) with maximum precision and consistency. With a pitch of 14 TPI and a 60° profile, this insert forms the complete thread geometry—crest, root, and flanks—in a single pass, ensuring strong, reliable threads in external machining applications.

Manufactured from high-performance P25C-grade carbide, this insert delivers excellent wear resistance, edge stability, and thermal control. It is ideal for threading challenging materials such as stainless steel and hardened alloys. The precise X and Y dimensions enable smooth chip evacuation and consistent cutting engagement.
