Sandvik Coromant 6532107 Grooving Insert N123RGR 4325

Product Description

The SANDVIK COROMANT 6532107 is a solid carbide grooving insert engineered for precision turning and grooving operations on CNC lathes and turning centers. It carries the manufacturer grade 4325 and features a multi-layer MT-CVD coating of TiCN, Al2O3, and TiN, delivering a hard, wear-resistant surface with improved thermal stability at the cutting edge. The insert has a neutral hand orientation and a cutting width of 0.5906 inches (15.00 mm), making it suitable for consistent, repeatable groove profiles. Machining professionals and CNC tool setters specify this insert for medium to high production environments where insert life and surface finish consistency are critical.

This insert belongs to the CoroCut 1-2 series, a platform designed for external and internal grooving, parting, and turning on a range of workpiece materials including steel, stainless, and cast iron. The GR chip breaker geometry and 13-degree rake angle support controlled chip evacuation during interrupted and continuous grooving cuts. It is suited for use on production turning centers in both job-shop and high-volume manufacturing settings. The insert size designation is R, with an ISO code of N123R1-1500-0010-GR 4325, and it is compatible with CoroCut 1-2 toolholders designed for that seat size.

Key Features

• Solid carbide substrate with MT-CVD TiCN, Al2O3, and TiN coating for extended wear resistance
• 0.5906 inch (15.00 mm) cutting width with a 0.0472 inch (1.20 mm) corner radius
• Neutral hand insert — usable in both left- and right-hand toolholder configurations where applicable
• GR chip breaker geometry promotes reliable chip control in grooving applications
• 13-degree rake angle supports reduced cutting forces during groove entry
• Multi-use designation allows use across grooving, parting, and turning operations within the CoroCut 1-2 system

Compatibility

Designed for use in CoroCut 1-2 series toolholders accepting insert seat size R. ISO code N123R1-1500-0010-GR 4325 should be used to confirm toolholder compatibility. Verify seat size and clamping geometry against the toolholder specification before installation.

Installation Notes

Insert replacement and seating should be performed by a qualified CNC machinist or tooling technician with the machine in a stopped, locked-out state per OSHA lockout-tagout procedures. Use the appropriate Torx or hex key specified by the toolholder manufacturer to seat and torque the clamping screw — do not overtighten. Inspect the insert pocket and seating surface for chips or debris before installing a new insert. Confirm insert orientation and hand before resuming cutting operations.
