It carries a CVD-applied Duratomic multilayer coating of TiCN, Al2O3, and Cr for extended tool life under high-heat cutting conditions. The insert features an 80-degree diamond shape, a 0.5 inch inscribed circle, and a 1\/64 inch (0.0157 inch) corner radius. With a negative rake angle of 18 degrees and a honed cutting edge, it delivers controlled chip formation through the MF1 chip breaker geometry. Four cutting edges are available per insert, reducing per-edge tooling cost. This insert is installed by machinists and CNC operators in production turning environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is rated for boring, facing, and turning operations. Its primary workpiece material is stainless steel (ISO material group M), with steel (group P) as the secondary application. Material grades M30 and M40 apply. The MF1 chip breaker geometry is suited for light to medium finishing cuts where controlled chip evacuation is critical. The neutral hand orientation makes it compatible with both right- and left-hand toolholders designed for CNMP-style inserts. ISO equivalent designation is CNMG120404-MF1.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD Duratomic multilayer coating: TiCN, Al2O3, and Cr for high wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape with negative rake for rigidity and edge strength\u003c\/li\u003e\n  \u003cli\u003eMF1 chip breaker geometry optimized for stainless steel and steel finishing cuts\u003c\/li\u003e\n  \u003cli\u003eFour usable cutting edges per insert for cost-effective tooling\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style reduces microchipping on difficult-to-machine alloys\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp, pin, and lever lock insert holding methods\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNMP-style toolholders accepting a 0.5 inch inscribed circle, 3\/16 inch thick diamond insert with clamp, pin, or lever lock holding.
