The insert features a square shape with a 90-degree included angle and an 11-degree relief angle, making it suited for positive-rake milling operations. A PVD-applied triple-layer TiN\/TiCN\/TiN coating provides thermal resistance and edge wear protection across demanding cutting cycles. The inscribed circle measures 0.3937 inches (10.00 mm) and the insert thickness is 0.1563 inches (5\/32 inch), with a corner radius of 0.0315 inches (0.80 mm). The GB2 chip breaker geometry promotes controlled chip evacuation during interrupted and continuous cuts. Licensed machinists and CNC tooling specialists are the primary installers of this insert type.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed for right-hand milling applications targeting steel, stainless steel, superalloys, and titanium workpieces, covering ISO material codes P, M, and S and material grades C5, C6, and C7. It is suited for face milling, shoulder milling, and similar milling operations where consistent edge performance across mixed-material production runs is required. The screw-holding method secures the insert in compatible toolholders designed for the SPET series. Typical environments include job shops and production machining facilities running ferrous and high-temperature alloy components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKC725M grade solid carbide with PVD TiN\/TiCN\/TiN multilayer coating for edge durability\u003c\/li\u003e\n  \u003cli\u003eSquare SPET insert shape with 90-degree included angle and 11-degree relief angle\u003c\/li\u003e\n  \u003cli\u003eGB2 chip breaker geometry for controlled chip flow in steel, stainless, and superalloy cuts\u003c\/li\u003e\n  \u003cli\u003e0.0315-inch (0.80 mm) corner radius minimizes edge chipping at entry and exit\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting orientation with screw-mount insert retention\u003c\/li\u003e\n  \u003cli\u003eCovers ISO material application codes P (steel), M (stainless steel), and S (superalloys and titanium)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in SPET-series screw-on milling toolholders compatible with inserts in the inscribed circle range of 0.3500 to 0.4000 inches and thickness range of 0.1500 to 0.1750 inches.
