Carmex Internal Right Hand ISO Metric Thread Turning Insert 16 mm / 3.5 mm Pitch / 16 IR 3.5 ISO P25C

Internal Thread Turning Insert – ISO Metric 60°

The Carmex 16 IR 3.5 ISO P25C is a high-performance internal thread turning insert designed for producing ISO metric (60°) thread profiles with a 3.5 mm pitch. It forms the complete thread geometry—crest, root, and flanks—in one precise operation, ensuring exceptional dimensional accuracy, smooth surface finish, and reliable performance in internal threading applications.

Manufactured from durable P25C-grade carbide, this insert provides excellent wear resistance, heat stability, and edge strength. It is ideally suited for threading steels and alloy steels under medium-speed cutting conditions, offering stable cutting action, effective chip evacuation, and long tool life even under heavy-duty machining environments.
