It carries a three-layer PVD coating of TiN, TiCN, and TiN, which improves wear resistance and edge life across a range of workpiece materials. The insert measures 0.6252 inches wide and 0.1875 inches thick, with a corner radius of 0.0472 inches (1.20 mm). It is screw-held, right-hand orientation, and suits CNC milling operations run by machinists and tooling technicians working with ferrous and high-temperature alloys.\u003c\/p\u003e\n\u003cp\u003eThis insert is rated for use on steel, stainless steel, superalloys, and titanium, corresponding to ISO material groups P, M, and S. It fits applications where edge stability and coating toughness are priorities, such as face milling, shoulder milling, and copy milling passes on difficult-to-machine materials. The KC725M grade with LN chip breaker geometry supports productive cuts in both roughing and semi-finishing operations on these material classes. Minimum order quantity is 5 inserts; each package contains 1.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThree-layer PVD coating: TiN, TiCN, TiN for extended wear resistance\u003c\/li\u003e\n  \u003cli\u003eKC725M grade suited for steel, stainless steel, superalloys, and titanium (ISO P, M, S)\u003c\/li\u003e\n  \u003cli\u003eRectangle insert shape with 90-degree included angle and 25-degree relief angle\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting orientation with LN chip breaker\u003c\/li\u003e\n  \u003cli\u003eScrew-held mounting for secure, repeatable insert positioning\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.0472 inches (1.20 mm) for controlled edge engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in LFEW-series milling toolholders and cutter bodies that accept LFEW220412 style inserts with screw-hold clamping.
