Iscar 6402478 Grooving Insert IC528 Chamgroove 1.2mm

Product Description

The ISCAR 6402478 is a solid carbide grooving insert in the ChamGroove series, designed for precise external grooving and parting operations on CNC lathes and turning centers. This right-hand insert carries the GIQR8120R060 form factor with a 1.2 mm cutting width and a maximum depth of cut of 1.5 mm. The IC528 grade features a PVD-applied TiCN and TiN coating, which provides wear resistance and thermal stability during interrupted cuts and high-speed passes. The full-radius geometry and screw-holding method make it a stable, repeatable choice for close-tolerance groove profiles. Installed by machinists and toolroom technicians in production and job-shop environments.

This insert is suited for grooving superalloys and titanium, materials classified under ISO material codes M, P, and S. The ChamGroove series addresses applications where tight groove width tolerances and surface finish consistency are required. It is a single-end insert, meaning each insert provides one cutting edge. The screw-clamping holding method delivers rigid seating in compatible ISCAR ChamGroove toolholders, reducing deflection during axial and radial grooving passes on difficult-to-machine workpiece materials.

Key Features

• Solid carbide IC528 grade with PVD TiCN and TiN coating for wear and heat resistance
• 1.2 mm cutting width with a full corner radius of 0.60 mm for consistent groove profiles
• Maximum depth of cut of 1.5 mm, suitable for shallow precision grooves
• Right-hand orientation, single-end design
• Screw-holding method for rigid, repeatable clamping in ChamGroove toolholders
• Conforms to ISO 13399 insert identification standards

Compatibility

Designed for use in ISCAR ChamGroove series toolholders that accept the GIQR insert style and 8120R060 insert size. Intended for machining superalloys and titanium workpieces. Confirm toolholder compatibility with the insert size code 8120R060 before ordering.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before changing inserts. Use the appropriate ISCAR torx or hex key to seat and torque the clamping screw per the toolholder manufacturer specifications. Inspect the toolholder pocket for chips or wear before seating a new insert to ensure proper clamping and edge repeatability.
