Iscar 6402803 Grooving Insert GIMF406F IC908 4mm

Product Description

The ISCAR 6402803 is a solid carbide grooving insert from the Cut-Grip series, designed for precision grooving and parting operations on CNC lathes and turning centers. It carries the IC908 grade with a PVD-applied TiAlN coating, which provides high wear resistance and thermal stability across a wide range of workpiece materials. The insert features a 4.00 mm cutting width, a maximum depth of cut of 2.40 mm, and a neutral hand orientation. A positive rake angle of 7 degrees and an F-style chip breaker promote controlled chip evacuation during continuous and interrupted groove cuts. This insert is installed by machinists and CNC turning specialists in production and job-shop environments.

The ISCAR 6402803 suits grooving applications across universal workpiece materials, including steel, stainless steel, cast iron, non-ferrous alloys, and high-temperature alloys, corresponding to ISO material groups P, M, K, H, and S. It is a single-end insert sized 406 within the GIMF insert style family, making it appropriate for shallow to medium-depth external grooving cycles on small- to mid-diameter workpieces. The multi-use designation indicates suitability for grooving, parting, and light turning operations within its depth-of-cut range.

Key Features

• IC908 grade with PVD TiAlN coating for extended tool life across universal workpiece materials
• 4.00 mm cutting width with a maximum depth of cut of 2.40 mm
• Positive rake angle of 7 degrees reduces cutting forces and promotes chip flow
• F-style chip breaker for controlled chip formation in grooving and parting
• Corner radius of 0.60 mm for blending groove walls without sharp stress concentration
• Clamp-style insert holding for secure, repeatable seating in compatible Cut-Grip toolholders
• Compliant with ISO 13399 for tooling data exchange

Compatibility

Designed as an OEM-style replacement insert for Cut-Grip series grooving toolholders accepting GIMF-style inserts in size 406. Specific toolholder compatibility should be verified against ISCAR Cut-Grip system documentation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. The machine spindle must be fully stopped and the turret or tool post locked out before seating or removing the insert. Use the correct ISCAR clamping key or torx driver as specified for the toolholder to avoid over-torquing the clamp screw. Inspect the insert pocket for chips or debris before seating the new insert to ensure full surface contact and accurate tool-nose positioning.
