This single-sided, square-shaped insert features a TiCN coating applied via CVD process, a medium grain carbide substrate, and a positive rake geometry with a T-Land cutting edge style. The 20-degree relief angle and ME16 chip breaker geometry are engineered for controlled chip evacuation and consistent performance in demanding milling applications. With four usable cutting edges and a 0.0394-inch corner radius, this insert delivers repeatable results across compatible face and shoulder milling operations.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for milling steel, stainless steel, superalloys, and titanium, covering material application codes P, M, and S. It fits the SEKR-12 series and is compatible with the Cutter Series R220.13-12. The neutral hand orientation and wedge clamp holding method make it a straightforward drop-in for properly configured toolholders. Typical users include CNC machinists and tooling technicians in production and job-shop environments working with ferrous and exotic alloy workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with CVD-applied TiCN coating for wear resistance in steel and stainless applications\u003c\/li\u003e\n  \u003cli\u003eSquare insert shape with 90-degree included angle and 0.0394-inch corner radius for shoulder and face milling\u003c\/li\u003e\n  \u003cli\u003e4 cutting edges per insert, single-sided, neutral hand orientation\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle with T-Land cutting edge style for controlled chip formation\u003c\/li\u003e\n  \u003cli\u003eME16 chip breaker geometry optimized for medium-grain carbide substrate performance\u003c\/li\u003e\n  \u003cli\u003eWedge clamp insert holding method; compatible with SEKR-12 series cutter bodies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with SEKR-12 series toolholders and confirmed compatible with Cutter Series R220.13-12.
