Manufactured to grade 4340 and coated via CVD process with a TiCN, Al2O3, and TiN multilayer stack, this insert delivers thermal resistance and wear durability across a wide range of workpiece materials. It measures 0.5433 inches (13.80 mm) inscribed circle and 0.1535 inches (3.90 mm) thick, with a positive 21-degree rake angle and a corner radius of 0.0787 inches (2.00 mm). It is designed for use in compatible Series 490 milling cutter bodies and is held in place by a screw-type clamping method.\u003c\/p\u003e\u003cp\u003eThis insert is suited for milling operations on steel, stainless steel, and cast iron in both roughing and semi-finish applications consistent with material grades P40, M40, and K40. The right-hand, single-sided square insert with corner-rounded cutting edge style is a fit for face milling, shoulder milling, and general-purpose milling work on CNC machining centers and manual milling machines. It carries ANSI and ISO classifications under code 490R-140420M-PH 4340 and is compatible with Series 490 cutter bodies. Maximum depth of cut reaches 0.3937 inches.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for extended tool life across varied workpiece materials\u003c\/li\u003e\n\u003cli\u003eGrade 4340 solid carbide substrate optimized for steel, stainless steel, and cast iron (P40, M40, K40)\u003c\/li\u003e\n\u003cli\u003eSquare insert shape with 4 cutting edges maximizes cost-per-edge efficiency\u003c\/li\u003e\n\u003cli\u003ePositive 21-degree rake angle reduces cutting forces and supports clean chip evacuation\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0787 inches (2.00 mm) with PH chip breaker geometry\u003c\/li\u003e\n\u003cli\u003eScrew-hold mounting for secure, repeatable seating in Series 490 toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Series 490 milling cutter bodies.
