Sandvik Coromant 5736239 Grooving Insert Carbide Corocut 1-2

Product Description

The SANDVIK COROMANT 5736239 is a solid carbide grooving insert engineered for precision parting and grooving operations on CNC turning centers and lathes. Manufactured to an N123JGM insert style with a neutral hand orientation, this insert features a 4.75 mm cutting width and a maximum depth of cut of 22.6 mm, making it well suited for medium to deep groove profiles. The MT-CVD-applied TiCN and Al2O3 coating delivers wear resistance and thermal stability at elevated cutting speeds. The GM chip breaker geometry promotes controlled chip evacuation in a wide range of workpiece materials. Machinists and tool room professionals install this insert as part of a modular tooling setup.

This insert is designed for the CoroCut 1-2 series tooling system and seats into size J insert seats. It fits standard CoroCut 1-2 holders configured for grooving and parting applications in both production turning and job shop environments. The 0.30 mm corner radius and 7-degree rake angle make this insert appropriate for general-purpose grooving across steel, stainless, and similar materials. The multi-use designation indicates suitability across a range of groove widths within the compatible depth range of 20.00 mm and above.

Installation Notes

Installation is performed by a qualified machinist or tool room technician. Disengage the machine spindle and lock out the turret before seating or replacing inserts. Use the appropriate Torx or hex key per the toolholder manufacturer's torque specification for the clamping screw. Inspect the insert seat for chips or debris before installation to ensure proper seating and avoid insert fracture during cutting.
