Carmex Internal Right Hand NPT Thread Turning Insert 22 mm / 22 IR N55 BMA
Internal Thread Turning Insert – Whitworth 55° Partial Profile
The Carmex 22 IR N55 BMA is a precision internal thread turning insert designed for cutting Whitworth (BSW/BSF) 55° thread profiles. As a partial-profile insert, it accommodates a wide pitch range (5.5–8.0 TPI), making it ideal for large-diameter and coarse-thread internal applications. The insert accurately forms the 55° thread flanks, ensuring excellent surface finish, high accuracy, and consistent thread quality for British Standard threading operations.
Manufactured from premium BMA-grade carbide, this insert provides exceptional wear resistance, edge strength, and thermal stability. It performs reliably on steels, stainless steels, and alloy materials, delivering consistent cutting performance, efficient chip control, and long tool life in both manual and CNC operations.
