Iscar 6404109 Grooving Insert GIP400E040P IC808 4mm

Product Description

The ISCAR 6404109 is a solid carbide grooving insert in the Cut-Grip series, designed for precision grooving and parting operations on CNC lathes and turning centers. It carries the GIP400E040P geometry and IC808 grade, a submicron carbide substrate with a PVD-applied AlTiN, TiAlN, and TiN multilayer coating. The insert delivers a 4 mm cutting width, a maximum depth of cut of 13 mm, and a corner radius of 0.40 mm. The double-ended design allows both ends to be used before replacement, extending tool life. A positive rake angle of 7 degrees and P-type chip breaker help manage chip flow across a wide range of workpiece materials.

This insert is suited for production turning environments where consistent groove geometry and long tool life are priorities. The IC808 grade with its PVD multilayer coating is rated for universal workpiece materials including steels, stainless steels, cast irons, non-ferrous materials, and high-temperature alloys, corresponding to ISO material groups P, M, K, H, and S. It is typically installed in Cut-Grip style grooving and parting toolholders by machinists and CNC programmers in job shops, production facilities, and maintenance machining environments. The double-end configuration and clamp-style insert holding method make indexing fast and repeatable.

Key Features

• IC808 submicron carbide grade with PVD AlTiN, TiAlN, and TiN multilayer coating for wear resistance
• 4 mm cutting width with a 0.40 mm corner radius for precise groove geometry
• 13 mm maximum depth of cut, suitable for moderate to deep grooving applications
• Double-ended insert design — both ends usable before replacement
• Positive 7-degree rake angle with P-type chip breaker for controlled chip evacuation
• Clamp-style insert holding compatible with standard Cut-Grip toolholders

Compatibility

Designed for use in Cut-Grip series grooving and parting toolholders that accept GIP-style inserts with the 400E040 size code. Verify toolholder seat geometry and clamping style before installation.

Installation Notes

Installation is performed by machinists following standard CNC tooling procedures. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torx or clamp key specified by the toolholder manufacturer to secure the insert — do not overtighten the clamp screw. Inspect the toolholder seat for chips or wear before seating the insert to ensure proper contact and alignment.
