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

Internal Thread Turning Insert – UN Full Profile 60o

The Carmex 16 IR 16 UN P25C is a precision internal thread turning insert designed for machining Unified (UN) 60o thread profiles with a 16 TPI pitch. It forms the complete thread geometry-crest, root, and flanks-in one operation, ensuring excellent thread accuracy, consistent form, and smooth surface finish for internal threading applications across various industries.

Manufactured from advanced P25C-grade carbide, this insert provides an ideal balance of wear resistance, toughness, and heat stability. It is particularly effective when threading steels and alloy steels at medium cutting speeds, delivering smooth cutting action, excellent chip control, and long-lasting tool life in both general-purpose and precision threading operations.
