Sandvik Coromant 6532090 Grooving Insert N123EGM 4325

Product Description

The SANDVIK COROMANT 6532090 is a solid carbide grooving insert designed for the CoroCut 1-2 series of parting and grooving toolholders. It carries manufacturer grade 4325 with a multilayer MT-CVD coating of TiCN, Al2O3, and TiN, providing wear resistance and thermal stability during interrupted or continuous grooving operations. The insert features a 2.39 mm cutting width, a maximum depth of cut of 18.40 mm, and a GM chip breaker geometry with a neutral rake angle of 7 degrees. ISO designation is N123E2-0239-0002-GM 4325. It is suited for CNC turning centers and is installed by machinists and tooling technicians working in precision metal removal applications.

This insert is intended for grooving, parting, and turning operations on CNC lathes and turning centers. The neutral hand orientation makes it compatible with both left- and right-hand toolholder setups within the CoroCut 1-2 system. The GM chip breaker is optimized for general-purpose grooving across a range of workpiece materials. The insert seat size is E and the overall insert size designation is E, fitting the corresponding CoroCut 1-2 blade and toolholder bodies designed for that seat classification. The maximum depth of cut range spans 10.00 mm to 20.00 mm, making it suitable for medium-depth groove profiles.

Compatibility

Designed for use with SANDVIK COROMANT CoroCut 1-2 series blades and toolholders accepting insert seat size E. ISO code N123E2-0239-0002-GM 4325 identifies the specific insert geometry and grade for correct toolholder matching.

Installation Notes

Installation is performed by qualified machinists or tooling technicians on CNC turning equipment. Power down and lock out the machine spindle before seating or removing inserts. Use the correct torx or clamping key specified for the CoroCut 1-2 toolholder body to secure the insert without overtightening. Inspect the insert seat for chips or debris before installation to ensure proper seating and repeatable tool geometry.
