Sandvik Coromant 7564337 Milling Insert Solid Carbide 490

Product Description

The SANDVIK COROMANT 7564337 is a solid carbide milling insert designed for use in 490-series milling cutters. Manufactured to ANSI and ISO standards under the code 490R-08T308M-PL 4340, this insert features a square shape with a positive rake angle of 32 degrees and a rounded corner edge style. The CVD-applied multilayer coating — TiCN, Al2O3, and TiN — provides wear resistance and thermal stability across a range of cutting conditions. With four cutting edges and a right-hand orientation, this insert is suited for high-productivity milling operations on ferrous and mixed-material workpieces.

This insert is intended for professional machining applications where steel, stainless steel, and cast iron are the primary workpiece materials, corresponding to material grades P40, M40, and K40. It fits 490-series milling cutter bodies and is held in place by a screw-mount method. Typical use cases include face milling and shoulder milling in both job shop and production environments. The PL chip breaker geometry supports controlled chip formation during moderate to heavy cuts. It is installed and managed by machinists and CNC setup technicians.

Key Features

• CVD multilayer coating: TiCN, Al2O3, TiN for extended tool life on hard and abrasive materials
• Square insert shape with 90-degree included angle and positive 32-degree rake for reduced cutting forces
• Four usable cutting edges per insert for cost-efficient indexing
• PL chip breaker geometry for controlled chip evacuation
• Screw-mount insert holding method for secure, repeatable seating
• Meets ANSI and ISO standards; ANSI/ISO code 490R-08T308M-PL 4340

Compatibility

Designed for use with 490-series milling cutter bodies. Insert size code 08T308 corresponds to the 490 cutter series as specified by the manufacturer. Verify cutter body compatibility with the 490R designation before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate Torx or hex key for the insert clamping screw and ensure the screw and pocket are clean and free of chips before seating the new insert. Follow the cutter body manufacturer's torque procedure for the clamping screw.
