Sandvik Coromant 6398216 Cutoff Insert 3mm Corocut Qd

Product Description

The SANDVIK COROMANT 6398216 is a solid carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. It belongs to the CoroCut QD series and carries the manufacturer catalog designation QD-RG-0300-0502-CM 1135. The insert features a 3.00 mm cutting width, a 5-degree right-hand lead angle, a 7-degree relief angle, and a 0.20 mm corner radius. A PVD-applied TiCN/Al2O3/TiN multilayer coating provides wear resistance and thermal stability at the cutting edge. The CM chipbreaker geometry is suited for chip control in a variety of workpiece materials. Licensed machinists and CNC operators install this insert as a replacement or production-quantity consumable in compatible QD-series toolholders.

This insert is intended for use in metalworking applications including turning, parting, and grooving of ferrous and non-ferrous materials on production and job-shop lathes. The G insert seat size and clamp-held mounting method are standard to the CoroCut QD platform. The right-hand insert hand designation means the insert is oriented for standard right-hand tool setups. It is sold individually with a minimum order quantity of 10 units, making it appropriate for shops that maintain a standing inventory of parting inserts.
