Sandvik Coromant 5736548 Grooving Insert 4mm Corocut 1-2

Product Description

The SANDVIK COROMANT 5736548 is a solid carbide grooving insert designed for precision external grooving operations on CNC turning centers and lathes. It carries the ISO designation N123H2-0400-0004-TM 2135 and belongs to the CoroCut 1-2 series, a widely used platform in production turning environments. The insert features a TiCN/Al2O3/TiN multilayer coating applied via MT-CVD process, delivering wear resistance and thermal stability across a range of workpiece materials. With a 4 mm cutting width and a maximum depth of cut of 23.40 mm, it suits medium to deep grooving passes. Licensed machinists and CNC operators in job shops and production facilities install this insert as a direct replacement in compatible CoroCut 1-2 toolholders.

This insert is suited for grooving applications in both high-volume production and general-purpose turning environments. The neutral hand orientation allows use in standard straight-cut grooving setups. The TM chip breaker geometry promotes controlled chip formation and evacuation, reducing cycle interruptions during deep groove passes. The grade 2135 substrate is formulated for stable cutting performance across a range of depths within the 20.00 mm and above depth-of-cut range. It is appropriate for use on ferrous and non-ferrous materials depending on setup parameters and machine rigidity.

Key Features

• Solid carbide substrate with MT-CVD applied TiCN/Al2O3/TiN multilayer coating for extended tool life
• 4 mm cutting width (0.1575 inches) with a 0.40 mm corner radius (0.0157 inches) for controlled groove geometry
• Maximum depth of cut of 23.40 mm (0.9210 inches) covering the 20.00 mm and above depth-of-cut range
• TM chip breaker designed for positive rake cutting and consistent chip control in deep groove applications
• Neutral hand orientation for use in standard straight grooving toolholder configurations
• Multi-use insert compatible with the CoroCut 1-2 toolholder platform

Compatibility

Designed as an OEM-style replacement insert for SANDVIK COROMANT CoroCut 1-2 series toolholders accepting H2 insert seat size. ISO code N123H2-0400-0004-TM 2135 should be cross-referenced against the toolholder specification to confirm fitment before installation.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. The machine spindle must be stopped and all axis motion confirmed halted before changing inserts. Use a calibrated torque wrench and the toolholder manufacturer-specified clamping screw to seat the insert properly — do not over-tighten by feel alone. Verify insert seating and clamping security before resuming cutting operations.
