It carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN under manufacturer grade 4340, providing wear resistance and thermal stability across a range of cutting applications. The insert measures 0.1563 inches thick and 0.6690 inches in length, with a convex radius of 0.3740 inches. It features a positive rake angle, a rounded cutting edge style, and a right-hand orientation. Two cutting edges per insert and an M-style chip breaker make it suited for moderate to aggressive metal removal in production environments. Installed by CNC machinists and tooling specialists.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for milling steel, stainless steel, and cast iron, covering ISO material groups P, M, and K. It fits RA216-series indexable ball nose cutter bodies and is secured with a screw-type holding method. Typical applications include profiling, contouring, and cavity milling in both roughing and semi-finishing passes. The insert size code is 19T3, and the ANSI and ISO designation is RA216-19 T3 M-M 4340. Maximum depth of cut reaches 0.6690 inches, making it appropriate for moderate stepdown passes on machining centers handling ferrous workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with CVD-applied TiCN, Al2O3, and TiN multilayer coating for extended tool life\u003c\/li\u003e\n  \u003cli\u003eBall nose insert shape with a convex radius of 0.3740 inches for profiling and contouring cuts\u003c\/li\u003e\n  \u003cli\u003eM-style chip breaker supports steel, stainless steel, and cast iron material groups P, M, and K\u003c\/li\u003e\n  \u003cli\u003ePositive rake geometry with rounded cutting edge style reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eRight-hand orientation, screw-mounted, single-sided with 2 cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003eConforms to both ANSI and ISO standards under designation RA216-19 T3 M-M 4340\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with RA216-series indexable ball nose milling cutter bodies.
