Carmex Internal Right Hand ISO Metric Thread Turning Insert 22 mm / 4.0 mm Pitch / 22 IR 4.0 ISO BMA

Internal Thread Turning Insert – ISO Metric 60°

The Carmex 22 IR 4.0 ISO BMA is a precision internal thread turning insert designed for producing ISO metric (60°) thread profiles with a 4.0 mm pitch. This full-profile insert forms the complete thread geometry—crest, root, and flanks—in a single pass, ensuring accurate thread form, consistent quality, and smooth surface finish in coarse-pitch internal threading applications.

Manufactured from premium BMA-grade carbide, it provides excellent wear resistance, edge stability, and thermal strength. The insert performs reliably on stainless steels, hardened alloys, and other difficult-to-machine materials, delivering smooth chip flow, reduced cutting forces, and long-lasting tool life in both general-purpose and precision threading operations.
