Sandvik Coromant 5737050 Grooving Insert Corocut 1-2

Product Description

The SANDVIK COROMANT 5737050 is a solid carbide grooving insert in the CoroCut 1-2 series, designed for external grooving, parting, and profiling operations on CNC lathes and turning centers. The insert carries a PVD-applied TiAlN/TiN coating over the ISO grade 1005 substrate, providing wear resistance and thermal stability at elevated cutting speeds. It features a 0.25-inch (6.35 mm) cutting width and a maximum depth of cut of 0.9488 inches (24.1 mm), with a GF chip breaker geometry and a neutral hand orientation. Machinists and CNC programmers working in production turning environments select this insert for consistent groove profiles and reliable edge life across a range of workpiece materials.

This insert is suited for external grooving and recessing operations on turning centers in both high-volume production and job-shop environments. The N123K insert style seats into CoroCut 1-2 compatible toolholders and blade systems. The neutral rake angle of 7 degrees and the GF chip breaker make it appropriate for applications requiring controlled chip evacuation and stable radial cutting forces. The insert size designation K corresponds to a seat size that matches standard CoroCut 1-2 blade and shank toolholder configurations. It is a multi-use insert suitable for grooving, light profiling, and parting where the cutting width and depth range align with the workpiece geometry.

Compatibility

Designed for use in CoroCut 1-2 series toolholders and blade systems that accept the N123K insert seat size. The ISO catalog number for this insert is N123K2-0635-0008-GF 1005.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Before seating the insert, ensure the machine spindle is stopped and the turret is indexed to a safe position with all drives disabled. Clean the insert pocket and clamping screw threads before seating the new insert, and verify the insert is fully seated against the pocket walls before torquing the clamping screw to the toolholder manufacturer specification. Handle carbide inserts with care to avoid chipping cutting edges prior to first use.
