Carmex Carmex Internal Right Hand UN Unified Thread Turning Insert 16 mm / 13 TPI / 16 IR 13 UN P25C

Internal Thread Turning Insert – UN Full Profile 60o

The Carmex 16 IR 13 UN P25C is a high-precision internal thread turning insert engineered for producing Unified (UN) 60o thread profiles with a 13 TPI pitch. It forms the complete thread geometry-crest, root, and flanks-in a single operation, ensuring superior dimensional accuracy, clean thread form, and excellent surface finish for internal threading applications.

Constructed from premium P25C-grade carbide, the insert offers an ideal combination of wear resistance, edge toughness, and heat stability. It performs exceptionally on steels and alloy steels under medium-speed cutting conditions, providing smooth chip control, reduced vibration, and reliable performance over extended tool life.
