Iscar 6404459 GIMIY404Y IC808 Grooving Insert 4mm

Product Description

The ISCAR 6404459 is a solid carbide grooving insert designed for precision turning and grooving operations on CNC lathes and turning centers. Carrying the GIMIY404Y insert style designation and IC808 manufacturer grade, this single-end insert features a 4 mm cutting width and a maximum depth of cut of 2 mm. The PVD-applied AlTiN, TiAlN, and TiN multilayer coating delivers strong heat resistance and edge wear performance across a broad range of workpiece materials. It is part of the Cut-Grip series and is installed by machinists and CNC tool setup technicians working in production and job-shop environments.

This insert is rated for universal primary workpiece material compatibility, covering ISO material groups H, K, M, P, and S. That range includes hardened steels, cast irons, stainless steels, general steels, and heat-resistant superalloys, making it a versatile choice for shops that run mixed-material production schedules. The clamp-style insert holding method seats the insert securely in a compatible Cut-Grip toolholder. The Y chip breaker geometry promotes chip control during shallow grooving passes typical of groove-and-part operations.

Key Features

• IC808 solid carbide grade with PVD-applied AlTiN, TiAlN, and TiN coating for extended tool life
• 4 mm cutting width with a maximum depth of cut range of 2 mm to 3 mm
• Neutral hand orientation for flexible toolholder mounting
• Y chip breaker geometry for improved chip evacuation in grooving applications
• Corner radius of 0.40 mm for controlled edge geometry at groove walls
• Multi-use insert compatible across ISO material groups H, K, M, P, and S

Compatibility

Designed for use with Cut-Grip series clamp-style toolholders that accept GIMIY-style inserts with a 404 insert size code. Verify toolholder pocket specifications before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician with the machine spindle fully stopped and the machine in a locked-out, tagged-out state. Use the appropriate torque wrench and clamping screw specified by the toolholder manufacturer — do not overtighten the clamp, as this can fracture the carbide substrate. Inspect the toolholder pocket for chips, debris, or wear before seating the insert. Confirm that the insert is fully seated and the clamp is secure before resuming any cutting operation.
