It features an 80-degree diamond shape with a 0.5 inch inscribed circle, a 1\/64 inch (0.0157 inch) corner radius, and a neutral hand orientation. The insert carries a CVD-applied Duratomic multilayer coating of TiCN, Al2O3, and Cr, engineered to extend tool life and maintain edge integrity under the thermal and mechanical demands of stainless steel and steel turning operations. Four cutting edges are available per insert, improving cost-per-edge efficiency in production environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for general turning, facing, and boring operations on stainless steel (ISO material code M) and steel (ISO material code P). It fits into toolholders accepting CNMP-style inserts with clamp, pin, or lever-lock holding methods. The MF1 chip breaker geometry is optimized for medium finishing passes, making this insert appropriate for shops running close-tolerance work on stainless alloys, carbon steels, and similar materials. It conforms to both ANSI and ISO standards, with the equivalent ISO designation CNMG120404-MF1.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD Duratomic coating (TiCN, Al2O3, Cr) for thermal resistance and extended tool life on stainless and steel\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape with negative rake angle for strong, stable cutting geometry\u003c\/li\u003e\n\u003cli\u003eMF1 chip breaker geometry tuned for medium finishing on stainless steel and steel workpieces\u003c\/li\u003e\n\u003cli\u003eFour usable cutting edges per insert for improved cost efficiency\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp, pin, and lever-lock toolholder systems\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and ISO standards; ISO equivalent CNMG120404-MF1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNMP-style toolholders accepting clamp, pin, or lever-lock insert retention.
