This square-shaped, right-hand insert features a multilayer PVD coating of TiN, TiCN, and TiN applied over a solid carbide substrate, delivering the wear resistance and edge toughness needed in demanding milling operations. It has a 15-degree relief angle, a 0.0315-inch corner radius, an inscribed circle of 0.5000 inches, and a thickness of 0.1875 inches. The GB2 chip breaker geometry supports controlled chip formation across a range of cutting conditions. Licensed contractors and machining professionals install this insert in compatible milling toolholders using a screw-clamp holding method.\u003c\/p\u003e\n\u003cp\u003eThis insert is rated for primary workpiece materials including steel, stainless steel, superalloys, and titanium, corresponding to ISO material codes P, M, and S. The KC725M grade and PVD coating combination make it well suited for both roughing and semi-finishing passes on difficult-to-machine alloys. Typical applications include face milling and shoulder milling operations on CNC machining centers in production and job-shop environments. The SDET series designation and size code 43 identify the insert family and body dimensions for proper toolholder matching.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with multilayer PVD coating: TiN, TiCN, TiN for extended wear life\u003c\/li\u003e\n  \u003cli\u003eKC725M grade optimized for steel, stainless steel, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003eGB2 chip breaker geometry for controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003eSquare insert shape with 90-degree included angle and 15-degree relief angle\u003c\/li\u003e\n  \u003cli\u003eScrew-clamp insert holding method for secure, repeatable seating\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut orientation; inscribed circle 0.5000 inches, corner radius 0.0315 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in SDET-series compatible milling toolholders accepting a square insert with a 0.5000-inch inscribed circle, 0.1875-inch thickness, and screw-clamp holding.
