Sandvik Coromant 6532129 Grooving Insert 4mm Corocut 1-2

Product Description

The SANDVIK COROMANT 6532129 is a solid carbide grooving insert designed for external and internal grooving operations on CNC lathes and turning centers. It carries a manufacturer grade of 4325 with a multilayer MT-CVD coating of TiCN, Al2O3, and TiN, delivering wear resistance and thermal stability across a range of workpiece materials. The insert has a 4.00 mm cutting width, a maximum depth of cut of 23.40 mm, and a corner radius of 0.40 mm. The neutral hand orientation makes it suitable for straight-in grooving without directional bias. This insert belongs to the CoroCut 1-2 series and is installed by machinists and CNC tooling technicians in production and job-shop environments.

This insert is used in grooving, parting, and profiling applications on CNC turning equipment. The TM chip breaker geometry promotes controlled chip formation, making it well-suited for medium to finishing cuts where chip evacuation and surface finish matter. The positive rake angle reduces cutting forces at the edge. Typical applications include groove turning on bar-fed lathes, turret lathes, and multi-spindle machines where consistent depth of cut and edge life are required. The insert is packaged individually with a minimum order quantity of 10 units.

Key Features

• 4.00 mm cutting width with a 0.40 mm corner radius for precise groove geometry
• Maximum depth of cut of 23.40 mm, covering a broad range of groove depths
• MT-CVD multilayer coating (TiCN / Al2O3 / TiN) for wear resistance and thermal protection
• TM chip breaker geometry for controlled chip formation during grooving and parting
• Positive rake angle reduces cutting forces and edge stress
• Neutral hand orientation fits standard CoroCut 1-2 toolholders without directional restriction

Compatibility

Designed for use with SANDVIK COROMANT CoroCut 1-2 series toolholders accepting H2 insert seat size. ISO code N123H2-0400-0004-TM 4325 identifies the precise toolholder interface and insert geometry required.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or replacing inserts. Use the correct torx or hex key specified for the CoroCut 1-2 clamping screw and do not overtighten. Inspect the insert pocket and clamping surfaces for chips or debris before seating the new insert to ensure proper edge alignment and repeatability.
