Sandvik Coromant 6508764 Grooving Insert 4mm Corocut 1-2

Product Description

The SANDVIK COROMANT 6508764 is a solid carbide grooving insert designed for external grooving and parting operations on CNC lathes and turning centers. Carrying manufacturer grade 4325 with a MT-CVD applied TiCN/Al2O3/TiN multilayer coating, this insert delivers controlled wear resistance and thermal stability in demanding turning applications. It features a 4 mm cutting width, a maximum depth of cut of 23 mm, and a neutral hand orientation with a GM chip breaker geometry. Machining professionals, toolroom technicians, and CNC operators install this insert as part of routine tooling maintenance or when setting up new grooving operations.

This insert is part of the CoroCut 1-2 series and is suited for grooving, parting, and profile turning on both small and medium-diameter workpieces. The neutral rake angle of 7 degrees and GM chip breaker geometry make it appropriate for a broad range of workpiece materials, including steels, stainless steels, and cast irons. It is sold individually with a minimum order quantity of 10 units, consistent with standard insert purchasing practice. The ISO code for this insert is N123H2-0400-0003-GM 4325.
