It carries the ANSI designation CNMP431-MF1 and ISO code CNMP120404-MF1, with a CVD-applied Duratomic multilayer coating of TiCN, Al2O3, and Cr for extended tool life. The insert features an 80-degree diamond (rhombic) shape, a 0.5-inch inscribed circle, a 1\/64-inch corner radius, and a neutral hand orientation. With 4 usable cutting edges and a honed cutting edge style, it delivers consistent performance in finishing passes on steel and stainless steel workpieces.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for finishing applications including boring, facing, and turning on CNC turning centers handling steel (ISO P) and stainless steel (ISO M) workpieces. The MF1 chip breaker geometry is optimized for finishing cuts with light depths of cut and controlled chip formation. Material grades M25, M30, and M35 cover a broad range of stainless steel and steel machining scenarios, making this insert a practical single-choice solution across moderate-wear and high-toughness cutting conditions. It is installed by machinists and CNC operators in job shop and production environments.\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 steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape with 4 cutting edges for efficient edge utilization\u003c\/li\u003e\n  \u003cli\u003eMF1 chip breaker geometry optimized for finishing operations\u003c\/li\u003e\n  \u003cli\u003eNegative rake, negative side clearance (N clearance code) for rigid, stable clamping\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp, pin, and lever lock insert holding methods\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style reduces micro-chipping during stainless steel finishing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct equivalent for toolholders accepting CNMP431 or CNMP120404 geometry inserts with clamp, pin, or lever lock holding methods.
