Carrying the ANSI and ISO designation R390-17 04 40E-NL H13A, this insert features a parallelogram shape with a positive rake angle of 28 degrees, a 4.00 mm corner radius, and an uncoated bright finish suited for precision cutting applications. It measures 4.76 mm thick and 17.00 mm wide, with a maximum depth of cut of 15.00 mm. The insert is held by screw and is intended for installation by qualified machining or toolroom professionals.\u003c\/p\u003e\u003cp\u003eThis insert is rated for non-ferrous metal workpiece materials under material grade classifications K20, N15, and S20, making it appropriate for aluminum, copper alloys, and similar materials in both production and jobshop environments. The NL chip breaker geometry and positive rake design help manage chip flow during high-speed milling operations. The insert is single-sided and right-hand oriented, with two available cutting edges per insert, providing a cost-effective solution for operators running R390-compatible toolholders in light to moderate material removal applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with uncoated bright finish for non-ferrous machining\u003c\/li\u003e\n\u003cli\u003ePositive rake angle of 28 degrees reduces cutting forces on the workpiece\u003c\/li\u003e\n\u003cli\u003e4.00 mm corner radius with rounded cutting edge style for smooth surface finish\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 15.00 mm supports shoulder and face milling operations\u003c\/li\u003e\n\u003cli\u003eNL chip breaker geometry promotes controlled chip evacuation\u003c\/li\u003e\n\u003cli\u003eTwo cutting edges per insert extend usable tool life\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with R390 series milling cutters.
