Carmex Internal Right Hand UN Unified Thread Turning Insert 16 mm / 10 TPI / 16 IR 10 UN P25C

Internal Thread Turning Insert – UN Full Profile 60°

The Carmex 16 IR 10 UN P25C is a precision internal thread turning insert designed for cutting Unified (UN) 60° thread profiles with a 10 TPI pitch. It accurately produces the full thread form—including crest, root, and flank geometry—in a single pass, ensuring excellent dimensional accuracy, superior surface quality, and consistent thread engagement in internal applications.

Manufactured from high-quality P25C-grade carbide, this insert offers a perfect combination of toughness, wear resistance, and heat stability. It is ideal for threading steels and alloy steels under medium cutting conditions, providing smooth chip flow, stable performance, and extended tool life for precision production threading.
