It carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides thermal resistance and wear protection during interrupted and continuous milling operations. The insert measures 3.96 mm (0.1563 inches) thick with an inscribed circle of 0.3740 inches and features a 0.80 mm (0.0315 inch) corner radius. It is a parallelogram-shaped, single-sided insert with a positive rake geometry and a corner-rounded cutting edge style. Licensed machinists, CNC operators, and tool room technicians install and index this insert in compatible milling toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for milling steel and cast iron workpieces, corresponding to ISO material codes P and K. The R215.44 series designation and insert size code 15T308 identify its seating geometry. The WL chip breaker geometry controls chip flow during face milling and shoulder milling applications in both roughing and finishing passes. It is a right-hand insert held in place by a screw-lock method. Maximum depth of cut reaches 0.5906 inches, making it appropriate for moderate material removal rates on ferrous workpieces in production and job shop environments.\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\u003eParallelogram insert shape with positive rake and corner-rounded cutting edge for smooth entry and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003e0.80 mm corner radius (0.0315 inches) provides edge strength while maintaining surface finish quality\u003c\/li\u003e\n  \u003cli\u003eWL chip breaker geometry for controlled chip evacuation on steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eScrew-lock insert holding method for secure, repeatable indexing\u003c\/li\u003e\n  \u003cli\u003eCompliant with both ANSI and ISO standards; ANSI\/ISO code R215.44-15T308M-WL 4030\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in R215.44 series milling toolholders accepting insert size code 15T308.
