Carmex Carmex Internal Right Hand UN Unified Thread Turning Insert 11 mm / 12 TPI / 11 IR 12 UN P25C

Internal Thread Turning Insert – UN Full Profile 60o

The Carmex 11 IR 12 UN P25C is a precision-engineered internal thread turning insert designed for producing Unified (UN) 60o thread profiles with a pitch of 12 TPI. It forms the complete thread geometry-crest, root, and flanks-in a single pass, ensuring high thread accuracy and a smooth surface finish in internal threading operations.

Manufactured from robust P25C-grade carbide, this insert provides an excellent combination of toughness and wear resistance, ideal for threading operations on steels and alloy steels. Its advanced chipbreaker geometry enhances chip control, stability, and heat dissipation, ensuring consistent performance and long tool life during medium-speed cutting.
