Sandvik Coromant 7564350 Milling Insert 4330 Carbide

Product Description

The SANDVIK COROMANT 7564350 is a solid carbide milling insert in grade 4330, designed for use in face and shoulder milling operations within the 490 cutter series. The insert features a square shape with a 90-degree included angle and a positive rake angle of 23 degrees, promoting efficient chip formation and reduced cutting forces. A CVD-applied triple-layer coating of TiCN, Al2O3, and TiN provides wear resistance and thermal stability across a range of cutting conditions. With four available cutting edges and a corner radius of 0.80 mm, this insert delivers consistent performance in both roughing and semi-finishing applications. It is intended for installation by machining professionals and toolroom technicians.

This insert is suited for milling steel and cast iron workpieces in both production and job-shop environments. The 490 series compatibility and PM chip breaker geometry make it appropriate for face milling, shoulder milling, and slotting operations where controlled chip evacuation is critical. The right-hand cutting orientation and screw-holding method are standard for 490-series toolholders. Material grade designations of P30, M30, and K30 indicate suitability across ISO material groups covering steel, stainless steel, and cast iron at moderate to high cutting speeds.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and locked out before handling or indexing inserts. Use the appropriate Torx or hex key as specified by the toolholder manufacturer when securing the clamping screw — do not overtighten. Inspect the insert pocket seat for chips or debris before seating a new insert to ensure proper contact and runout accuracy.
