It carries an ANSI insert code of CNMG431 and an ISO equivalent of CNMG120404. The insert is manufactured from carbide in grade ACM25P with a PVD coating and features the IPK+ chip breaker geometry. With a diamond (rhombic) 80-degree insert shape, a 0.40 mm (0.0157 inch) corner radius, and four usable cutting edges, this insert delivers a dependable cost-per-edge value for medium-duty turning applications.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning steel, stainless steel, and special or super alloys in both residential shop and industrial production environments. The ACM25P grade provides high wear resistance through the full range to high toughness for steel (P-class workpieces), high wear resistance to moderate wear resistance and toughness for stainless steel (M-class), and moderate wear resistance and toughness for special and super alloys (S-class). It is used by machinists and CNC operators running roughing-to-finishing passes where consistent chip control and tool life are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCNMG431 \/ CNMG120404 insert geometry with 80-degree diamond shape for strong cutting edge\u003c\/li\u003e\n\u003cli\u003ePVD-coated ACM25P carbide grade rated for P, M, and S primary workpiece material codes\u003c\/li\u003e\n\u003cli\u003eIPK+ chip breaker for effective chip control across steel and stainless applications\u003c\/li\u003e\n\u003cli\u003eFour cutting edges per insert with negative side clearance (clearance code N)\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation compatible with both left- and right-hand toolholders\u003c\/li\u003e\n\u003cli\u003eCompatible holding methods include clamp, lever lock, pin, and screw\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard indexable insert for CNMG431-compatible toolholders with a 0.2031-inch hole diameter.
