Manufactured to grade 4030 with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, this insert delivers wear resistance and thermal stability during medium to heavy milling operations. The parallelogram insert shape features a positive rake geometry and a corner-rounded cutting edge style with a 0.41 mm corner radius. It measures 3.96 mm thick and carries insert size code 15T304. Installation is performed by machinists and tooling technicians working with compatible R215.44 series milling toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for milling steel and cast iron workpieces in both roughing and semi-finishing applications. The positive rake geometry reduces cutting forces, making it appropriate for operations where minimizing spindle load or machining thin-walled components is a priority. The WL chip breaker geometry supports reliable chip evacuation across a range of feed rates. With a maximum depth of cut of 0.5906 inches and an inscribed circle of 0.3740 inches, this insert is configured for moderate material removal rates in ferrous machining environments. It is a single-sided insert secured by a screw-style clamping method.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 4030 solid carbide substrate with CVD multilayer TiCN, Al2O3, and TiN coating for wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003ePositive rake, corner-rounded cutting edge reduces cutting forces on steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eWL chip breaker geometry promotes consistent chip control across varied feed conditions\u003c\/li\u003e\n  \u003cli\u003eRight-hand insert orientation with screw-style holding for secure seating in the toolholder\u003c\/li\u003e\n  \u003cli\u003eInsert size code 15T304 with 0.41 mm corner radius for controlled edge geometry\u003c\/li\u003e\n  \u003cli\u003eCompliant with ANSI and ISO standards; ANSI and ISO code R215.44-15T304M-WL 4030\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in SANDVIK COROMANT R215.44 series milling toolholders.
