It features an 80-degree diamond (rhombic) shape with a neutral hand orientation and a negative rake and relief angle geometry. The inscribed circle measures 0.5 inches, the corner radius is 0.0157 inches (1\/64 inch), and the insert thickness is 0.1875 inches (3\/16 inch). The WSM30 grade substrate is finished with a multilayer PVD coating  -  TiAlN, Al2O3, and ZrCN  -  engineered for wear resistance and thermal stability in demanding cutting operations. Licensed HVAC techs and machinists in precision metalworking rely on this insert for roughing and medium machining applications.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed primarily for turning, facing, and boring of stainless steel and superalloys and titanium (ISO material codes M and S). It also performs in steel applications (ISO code P), making it a versatile choice for shops working across multiple workpiece materials. The NM4 chip breaker geometry is optimized for roughing and medium machining passes, and the four available cutting edges allow rotation to extend tooling life before replacement. The insert is held in place using a clamp or pin method and fits standard CNMG-style toolholders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMultilayer PVD coating (TiAlN, Al2O3, ZrCN) for thermal and wear resistance in stainless steel and superalloy cuts\u003c\/li\u003e\n  \u003cli\u003eNM4 chip breaker geometry suited for roughing and medium machining operations\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert for extended tooling economy\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape provides a strong cutting edge with a 20-degree rake angle\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style reduces chipping risk at entry and exit of cut\u003c\/li\u003e\n  \u003cli\u003eCompatible with both clamp and pin holding methods in standard CNMG toolholders\u003c\/li\u003e\n  \u003cli\u003eDual standards compliance: ANSI (CNMG431) and ISO (CNMG120404)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard CNMG-style toolholders accepting a 0.5-inch inscribed circle insert.
