It is manufactured to the KCPM40 grade and features a dual PVD coating of TiAlN and AlCrN, which provides thermal resistance and edge durability during aggressive milling operations. The insert has a 1.0000-inch inscribed circle, a 0.3750-inch thickness, and a positive rake geometry with a 7-degree relief angle. Four cutting edges are available per insert. The HF chip breaker and chamfered, honed cutting edge style make this insert well suited for finishing and semi-finishing applications in ferrous and high-temperature alloy materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed for milling steel, stainless steel, superalloys, and titanium workpieces, corresponding to ISO material groups P, M, and S. It is compatible with the KSRM cutter series and is intended for use by machinists and CNC tool-room technicians in both production and job-shop environments. The neutral hand designation allows use in standard toolholder orientations. Typical applications include face milling, shoulder milling, and contour milling on CNC machining centers where consistent surface finish and predictable tool life are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with PVD-applied TiAlN and AlCrN dual coating for extended thermal and wear resistance\u003c\/li\u003e\n  \u003cli\u003eKCPM40 grade optimized for steel, stainless steel, superalloys, and titanium (ISO P, M, S materials)\u003c\/li\u003e\n  \u003cli\u003eRound RCGT insert shape provides 4 usable cutting edges and full 360-degree included angle\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle of 25 degrees with 7-degree relief reduces cutting forces on workpiece\u003c\/li\u003e\n  \u003cli\u003eHF chip breaker with chamfered and honed edge style suited for finishing and semi-finishing cuts\u003c\/li\u003e\n  \u003cli\u003eScrew-held, single-sided insert with neutral hand for straightforward toolholder mounting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the KENNAMETAL KSRM cutter series.
