Sandvik Coromant 5736203 Grooving Insert Corocut 1-2

Product Description

The SANDVIK COROMANT 5736203 is a solid carbide grooving insert designed for the CoroCut 1-2 series of parting and grooving toolholders. It carries a multi-layer MT-CVD coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal stability during continuous or interrupted grooving operations. The insert has a neutral hand orientation, a 4 mm cutting width, and a maximum depth of cut of 23 mm, making it suitable for moderate to deep grooving passes. The GM chip breaker geometry supports reliable chip control across a range of materials. This insert is installed by machinists and CNC lathe operators in production turning environments.

This insert is used in external and internal grooving, parting, and face grooving applications on CNC lathes and turning centers. The CoroCut 1-2 series is a common platform in both job-shop and high-volume production settings. The 4 mm cutting width and 23 mm maximum depth suit applications such as snap-ring grooves, undercuts, and part-off operations on bar stock or chucked workpieces. The ISO code N123H2-0400-0003-GM 2135 can be used to cross-reference compatible toolholders and spare parts within the CoroCut 1-2 system.

Compatibility

Designed for use with SANDVIK COROMANT CoroCut 1-2 series toolholders accepting insert seat size H. The ISO catalog number N123H2-0400-0003-GM 2135 identifies the precise toolholder seat and insert geometry required for correct fitment.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. The machine spindle must be stopped and all stored energy released before changing inserts. Use the correct Torx or hex key specified for the CoroCut 1-2 clamping screw to seat the insert fully without rocking. Inspect the insert pocket and clamping screw for wear or damage before seating a new insert.
