Sandvik Coromant 7564357 Square Milling Insert 4340

Product Description

The SANDVIK COROMANT 7564357 is a solid carbide milling insert engineered for high-performance metal cutting in demanding machining environments. 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.

This 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.

Key Features

• Square insert shape with 4 cutting edges maximizes cost-per-edge efficiency
• Positive 21-degree rake angle reduces cutting forces and supports clean chip evacuation
• Corner radius of 0.0787 inches (2.00 mm) with PH chip breaker geometry
• Screw-hold mounting for secure, repeatable seating in Series 490 toolholders

Compatibility

Designed for use with Series 490 milling cutter bodies. ANSI and ISO catalog designation: 490R-140420M-PH 4340. Insert size code: 140420.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the appropriate Torx or hex key for the clamping screw and ensure the insert seat is clean and free of chips before seating the new insert. Follow the cutter manufacturer's guidelines for insert indexing and torque procedures as specified in the toolholder documentation.
