Sandvik Coromant 7564348 Milling Insert 4330 Solid Carbide

Product Description

The SANDVIK COROMANT 7564348 is a solid carbide milling insert designed for use in Series 490 face and shoulder milling cutter bodies. Manufactured to ANSI and ISO standards under catalog designation 490R-140408M-PL 4330, this square-shaped insert carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN. The 4330 manufacturer grade corresponds to material application grades P30, M30, and K30, making it suitable for productive cutting in steel and cast iron. With a positive rake angle of 26 degrees and a corner-rounded cutting edge style, it is engineered for consistent chip control using the PL chip breaker geometry. Licensed machinists and CNC tooling professionals install this insert in production and job-shop milling operations.

This insert is intended for use in Series 490 milling cutter bodies where the 490R-140408M-PL geometry is specified. Primary workpiece materials are steel (P-class) and cast iron (K-class). The right-hand, single-sided configuration with four cutting edges suits high-volume facing, shouldering, and profiling operations on CNC machining centers. The screw-clamping insert holding method provides secure seating under interrupted and continuous cut conditions. Typical applications include structural steel components, gray and ductile cast iron parts, and general-purpose machining in both light and medium stock-removal scenarios.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for wear resistance and thermal stability
• 4330 manufacturer grade with P30, M30, and K30 material grade classification
• Square insert shape with four usable cutting edges, right-hand orientation
• Positive rake geometry at 26 degrees with PL chip breaker for effective chip evacuation
• Corner-rounded cutting edge with 0.80 mm (0.0315 inch) corner radius
• Screw-type insert holding method compatible with Series 490 cutter bodies

Compatibility

Designed for use in Sandvik Coromant Series 490 milling cutter bodies. ANSI and ISO designation is 490R-140408M-PL 4330. Cutter series compatibility is confirmed for the 490 series. Consult the cutter body documentation to verify seat geometry and insert pocket dimensions before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Disengage machine power and lock out the spindle before changing inserts. Use the appropriate Torx or hex key specified by the cutter body manufacturer when tightening the clamping screw — do not exceed the torque guidance provided in the cutter body documentation. Inspect the insert pocket seat and clamping screw for wear or debris before seating a new insert.
