The SANDVIK COROMANT 5737039 is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. Identified by ISO code N123K2-0635-0003-GM 3115, this insert features a 6.35 mm (0.2500 inch) cutting width and a maximum depth of cut of 22.60 mm (0.8898 inch). The manufacturer grade 3115 coating combines MT-CVD-applied TiCN and Al2O3 layers to deliver wear resistance and thermal stability in demanding cut conditions. The neutral hand orientation and GM chip breaker geometry make this insert a reliable choice for machinists running high-volume grooving work in ferrous and non-ferrous materials.
This insert belongs to the CoroCut 1-2 series, a platform widely used in production turning environments for grooving, parting, and face grooving applications. It is suited for residential shop and industrial production settings alike, wherever repeatable groove geometry and consistent surface finish are required. The insert size K and seat size K designations confirm proper seating in compatible CoroCut 1-2 toolholders. The neutral rake angle of 7.00 degrees and 0.25 mm corner radius support clean entry and exit in tight-tolerance groove profiles.
Designed for use with SANDVIK COROMANT CoroCut 1-2 series toolholders accepting insert seat size K. ISO catalog number N123K2-0635-0003-GM 3115 identifies the exact toolholder interface required for proper seating and clamping.
Installation is performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before seating or replacing any insert. Ensure the insert pocket and clamping surfaces are clean and free of chips before seating the insert to avoid micro-fractures from uneven clamping load. Do not exceed the toolholder manufacturer recommended depth-of-cut range for the specific holder used with this insert.
