Sandvik Coromant 6398183 Cutoff Insert 2.5mm Corocut Qd

Product Description

The SANDVIK COROMANT 6398183 is a solid carbide cutoff and grooving insert designed for the CoroCut QD series parting and grooving system. It carries a 2.5 mm (0.0984 inch) cutting width with a neutral hand orientation, making it compatible with standard QD-style toolholders used in CNC turning applications. The insert is manufactured in grade 1135 and features a PVD-applied TiCN/Al2O3/TiN multilayer coating for wear resistance in demanding parting and grooving operations. A CM chipbreaker geometry controls chip flow. The corner radius is 0.20 mm (0.0079 inch) and the relief angle is 7 degrees. This insert is installed and replaced by machinists and CNC turning specialists in production and job-shop environments.

The 6398183 is suited for parting and grooving operations on CNC lathes and turning centers in both production and job-shop settings. The CoroCut QD series is designed for deep grooving and parting-off applications where chip control and insert stability are critical. The insert is appropriate for use on steel and other materials where a PVD-coated grade 1135 carbide insert with a CM chipbreaker provides effective performance. This insert is sold individually with a minimum order quantity of 10 units.
