It carries a CVD-applied trilayer coating of TiCN, Al2O3, and TiN under manufacturer grade 4340, targeting demanding cutting operations in steel, stainless steel, and cast iron. The insert measures 0.1875 inches thick with an inscribed circle of 0.3780 inches and features a parallelogram shape with a positive 22-degree rake angle. Two cutting edges are provided per insert, and a corner radius of 0.1220 inches (3.10 mm) supports controlled chip formation at moderate to aggressive depths of cut up to 0.6181 inches.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for industrial milling applications in both roughing and semi-finishing passes on P, M, and K material groups  -  steel, stainless steel, and cast iron. It is a right-hand insert secured by screw-clamping and is intended for use in R390-series toolholders and cutter bodies. Typical installation environments include CNC machining centers performing shoulder milling, face milling, or slot milling operations. The PM chip breaker geometry is optimized for general-purpose cutting across the listed workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD trilayer coating: TiCN, Al2O3, TiN for wear resistance across P, M, and K material groups\u003c\/li\u003e\n  \u003cli\u003ePositive 22-degree rake angle reduces cutting forces on the workpiece\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.1220 inches (3.10 mm) with corner-rounded cutting edge style\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.6181 inches supports aggressive material removal\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert; single-sided design with screw-clamp holding method\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO standards; ANSI\/ISO code R390-17 04 31E-PM 4340\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in R390-series milling cutter bodies.
