Sandvik Coromant 6532128 Grooving Insert Corocut 1-2 3mm

Product Description

The SANDVIK COROMANT 6532128 is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC turning centers and lathes. It carries a manufacturer grade of 4325 with a multi-layer MT-CVD coating of TiCN, Al2O3, and TiN, delivering wear resistance and thermal stability in demanding metal-cutting applications. The insert features a 3 mm cutting width, a maximum depth of cut of 18.4 mm, and a positive rake geometry with a TM chip breaker. Licensed machinists and CNC operators install this insert as a direct replacement in compatible CoroCut 1-2 tooling systems.

This insert is suited for grooving operations in both production and job-shop environments, including those working with steel, stainless steel, and similar ISO-coded workpiece materials. The neutral hand orientation supports standard right-hand turning setups. With an ISO code of N123G2-0300-0004-TM 4325, it fits into G-seat, G2 insert-size toolholders within the CoroCut 1-2 platform. Typical applications include external grooving, recessing, and parting on medium to large diameter workpieces where consistent chip control and tool life are priorities.

Compatibility

Designed for use with CoroCut 1-2 series toolholders accepting a G-seat, G2 insert size. ISO code N123G2-0300-0004-TM 4325 should be referenced when selecting a compatible toolholder or insert seat.

Installation Notes

Installation is performed by a qualified CNC machinist or toolroom technician. Power down and lock out the machine spindle before seating or removing any insert. Use the appropriate torx or hex key as specified by the toolholder manufacturer when securing the clamping screw — do not overtighten. Inspect the insert seat and clamping surfaces for chips or debris before seating the new insert to ensure proper contact and runout.
