It carries manufacturer grade TM3501 and is designed for general-purpose metal cutting operations including turning, facing, and boring. The insert features an 80-degree diamond shape, a neutral hand orientation, and a chamfered and honed cutting edge style with a negative rake angle of 18 degrees. With four usable cutting edges and compatibility with clamp, pin, and lever lock holding methods, it is suited for high-productivity machining environments. Machinists and CNC lathe operators working in job shop and production settings are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered for primary use on stainless steel workpieces (ISO material code M, grade M30 and M40) and secondary use on steel (ISO material code P). Its M3 chip breaker geometry is optimized for medium to heavy cutting conditions where chip control and edge stability are critical. The insert meets both ANSI and ISO standards and carries ISO designation CNMG120408-M3 alongside the ANSI industry standard number CNMG432-M3. Multi-use capability across boring, facing, and turning operations makes it a versatile choice for shops running varied workpiece profiles in stainless and carbon steel materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDuratomic CVD multilayer coating (TiCN, Al2O3, Cr) for wear resistance on stainless and steel\u003c\/li\u003e\n  \u003cli\u003eM3 chip breaker geometry optimized for medium to heavy cutting depths\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges for extended insert life and lower per-edge cost\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape with chamfered and honed cutting edge for edge strength\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp, pin, and lever lock toolholding systems\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards; dual-coded CNMG432-M3 and CNMG120408-M3\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNMG-style indexable toolholders that accept CNMG432 (ISO: CNMG120408) inserts with clamp, pin, or lever lock holding methods.
