Value Collection CNMG120408SPB15 Carbide Turning Insert

Product Description

The VALUE COLLECTION CNMG120408SPB15 is a CNMG-style carbide turning insert designed for metal cutting operations on CNC lathes and turning centers. It carries the ANSI designation CNMG432 and the ISO designation CNMG120408, with a manufacturer grade of ICP22 and an aluminum oxide (Al2O3) coating. The insert features an 80-degree diamond (rhombic) shape, a negative side clearance, and a G-style chip breaker. With a 0.5-inch inscribed circle and a 0.0315-inch corner radius, it is suited for general-purpose turning where controlled chip formation and surface finish consistency are priorities.

This insert is intended for use in standard CNMG toolholders that accept the 432 size code and are configured for clamp-and-pin holding. It is applicable to workpiece material codes K and N, indicating suitability for cast iron, non-ferrous metals, and similar materials. Material grades C5 and C6 align it with finishing to semi-finishing turning applications. Licensed machinists and CNC turning technicians are the primary installers in production and job-shop environments.
