Sandvik Coromant 5736432 Grooving Insert Corocut 3

Product Description

The SANDVIK COROMANT 5736432 is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. Carrying the ISO designation N123T3-0120-0000-GS 1125, this insert features a 1.2 mm cutting width and a maximum depth of cut of 2.3 mm. The TiAlN coating is applied via PVD process, delivering a hard, heat-resistant surface layer that extends tool life in demanding cutting conditions. A 7-degree rake angle and neutral hand orientation make this insert suitable for a broad range of workpiece materials and grooving applications. Installation and replacement are handled by qualified CNC machinists and toolroom technicians.

This insert belongs to the CoroCut 3 series, which is engineered for three-edge grooving operations requiring close tolerances and consistent chip control. The GS chip breaker geometry is suited for general-purpose grooving across a depth-of-cut range of 2.0 mm to 3.0 mm. The insert size designation is T, and the insert seat size is T, confirming correct holder pairing. Its neutral hand configuration supports use in standard right- or left-hand toolholder setups without modification.

Key Features

• GS chip breaker geometry optimized for general-purpose grooving in the 2.0 mm to 3.0 mm depth range
• 7-degree rake angle for efficient chip formation and reduced cutting forces
• Neutral hand orientation compatible with standard grooving toolholders
• ISO code N123T3-0120-0000-GS 1125 for precise holder and system matching

Compatibility

Designed for use in CoroCut 3 series toolholders that accept size T insert seats, as specified by the ISO designation N123T3-0120-0000-GS 1125. Verify holder compatibility using the full ISO code before installation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician with the machine in a full stop, locked-out, and tagged-out condition before handling inserts or toolholders. Use the appropriate torx or clamping key specified by the toolholder manufacturer when seating the insert; do not overtighten or use improvised tools. Inspect the insert seat and clamping mechanism for wear or debris before each insert change. Follow the toolholder manufacturer guidelines and applicable shop safety standards when setting tool offsets and running break-in passes.
