Sandvik Coromant 5736202 Grooving Insert N123HGM 1145

Product Description

The SANDVIK COROMANT 5736202 is a solid carbide grooving insert designed for precision groove turning and parting operations on CNC lathes and turning centers. It carries the ISO designation N123H2-0400-0003-GM 1145 and belongs to the CoroCut 1-2 series. The insert features a TiAlN and AlCr2O3 PVD coating finish that supports extended tool life under high-temperature cutting conditions. With a 4 mm cutting width and a maximum depth of cut of 23 mm, this insert handles a broad range of grooving depths in a single setup. The GM chip breaker geometry and 7-degree rake angle promote controlled chip evacuation in both general and interrupted cut applications. Machinists and CNC programmers specify this insert for high-volume production environments where dimensional consistency is critical.

This insert is suited for external and internal grooving operations across a wide variety of workpiece materials, including steel, stainless steel, and non-ferrous alloys, depending on grade selection. The neutral hand orientation allows use in either left- or right-hand toolholders compatible with the CoroCut 1-2 system. Typical applications include O-ring groove machining, face grooving, and parting on precision turned components in aerospace, automotive, and general engineering environments. Installation requires a CoroCut 1-2 compatible toolholder accepting size H insert seats. The multi-use tool designation confirms suitability for repeat-operation tooling setups.

Key Features

• 4 mm cutting width with 0.30 mm corner radius for precise groove geometry
• Maximum depth of cut of 23 mm, suitable for deep grooving operations
• TiAlN and AlCr2O3 PVD coating for elevated heat and wear resistance
• GM chip breaker geometry promotes reliable chip control and evacuation
• Neutral hand orientation compatible with both left- and right-hand CoroCut 1-2 toolholders
• 7-degree rake angle supports reduced cutting forces and smooth chip flow

Compatibility

Designed for use with CoroCut 1-2 series toolholders accepting size H insert seats. ISO code N123H2-0400-0003-GM 1145 confirms fitment requirements. Confirm toolholder seat size and clamping style before installation.

Installation Notes

Installation is performed by qualified machinists or CNC toolroom technicians. Power down and lock out the machine spindle before seating or removing the insert. Use the correct torx or clamping screw as specified by the toolholder manufacturer - do not substitute fastener sizes. Inspect the insert seat for chips or debris before clamping to ensure accurate seating and repeatable tool-tip position.
