Sandvik Coromant 7564423 Milling Insert Solid Carbide

Product Description

The SANDVIK COROMANT 7564423 is a solid carbide square milling insert designed for high-productivity metal removal in steel, stainless steel, and cast iron applications. Manufactured to Grade 4340 with a CVD-applied TiCN, Al2O3, and TiN multilayer coating, this insert delivers thermal resistance and wear protection across demanding cutting conditions. It features a negative rake angle of 30 degrees, a corner radius of 0.80 mm (0.0315 inches), and an inscribed circle of 13.00 mm (0.5118 inches). With eight available cutting edges on a double-sided configuration, it offers extended service life per insert. The insert mounts via screw-hold in Series 345 milling cutter bodies.

This insert is suited for face milling and shoulder milling operations in both roughing and semi-finishing passes on steel and cast iron workpieces. It fits Series 345 cutter bodies and is identified by ANSI and ISO code 345R-1305M-PL 4340, with a PL chip breaker geometry optimized for steel and stainless steel chip control. The right-hand cutting configuration and 90-degree included angle make it a standard choice for square-shoulder milling setups. Machinists and CNC operators in job shops, tool rooms, and production machining environments install this insert as a direct-fit component for compatible 345-series toolholders.

Installation Notes

Installation is performed by a machinist or CNC setup technician using a torx or hex key to secure the insert screw. Power down and lock out the machine spindle before seating or replacing inserts. Inspect the insert pocket and clamping screw for wear or debris before installation. Do not use damaged or chipped inserts, and verify correct insert orientation for right-hand cutting direction before resuming operation.
