Iscar 6403688 GIMY525F IC908 Grooving Insert 5mm

Product Description

The ISCAR 6403688 is a solid carbide grooving insert in the Cut-Grip series, carrying the GIMY525F geometry and IC908 manufacturer grade with a PVD-applied TiAlN coating. Designed for precision grooving and parting operations on CNC turning centers and lathes, this insert delivers a 5.00 mm cutting width and a maximum depth of cut of 2.50 mm. The IC908 grade is suited for universal workpiece material applications, spanning steel, stainless, cast iron, and high-temperature alloys. A positive rake angle of 7 degrees and an F chip breaker geometry promote clean chip formation and reduced cutting forces. This insert is installed by CNC machinists and tool-room technicians performing grooving, parting, or undercut operations.

This insert is intended for external and internal grooving applications on a wide range of workpiece materials. Its neutral hand orientation makes it adaptable to both left- and right-hand tool holders compatible with the GIMY 525F seat. The universal primary workpiece material classification covers ISO material groups H, K, M, P, and S, making it appropriate for production environments that machine varied stock. The F chip breaker is optimized for finishing cuts within the maximum depth of cut range of 2.00 mm to 3.00 mm.

Compatibility

Designed for use with Cut-Grip series tool holders accepting the GIMY 525F insert seat configuration. Consult the ISCAR Cut-Grip system documentation to confirm holder compatibility before installation.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Power down and lock out the machine spindle before seating or removing inserts. Use the correct clamping screw and torque driver specified by the tool holder manufacturer — do not substitute fasteners. Verify insert seating and clamp engagement before resuming cutting operations.
