Iscar 6403357 GEPI200010 IC908 Grooving Insert Cut-grip

Product Description

The ISCAR 6403357 is a solid carbide grooving insert in the Cut-Grip series, designed for precision grooving and parting operations on CNC lathes and turning centers. Carrying the GEPI200010 insert style designation and manufactured to the IC908 grade, it features a PVD-applied TiAlN coating over a submicron carbide substrate. The cutting width is 2.01 mm (0.079 inches) with a maximum depth of cut reaching 8.99 mm (0.354 inches). A positive rake angle of 8 degrees and a self-grip insert holding method keep the insert seated securely under interrupted cuts and high-feed passes. This insert is installed by machinists and CNC tooling technicians in production and job-shop environments.

This insert fits grooving and cut-off toolholders compatible with the GEPI-style self-grip seat geometry within the Cut-Grip series. It is rated for universal workpiece material application, covering ISO material groups H, K, M, P, and S, making it suitable for carbon steels, stainless steels, cast irons, hardened materials, and high-temperature alloys. The double-end geometry allows the insert to be flipped for a second cutting edge, extending usable tool life. Typical applications include external grooving, plunge grooving, and shallow profiling where a 2.01 mm slot width is required.

Key Features

• IC908 grade with PVD TiAlN coating for wear resistance across universal workpiece materials
• Submicron solid carbide substrate for edge toughness in interrupted and continuous cuts
• 2.01 mm cutting width with 8.99 mm maximum depth of cut
• Positive 8-degree rake angle reduces cutting forces and heat generation
• Double-end insert provides two usable cutting edges per insert
• Self-grip seating method eliminates clamping screws and simplifies insert changes
• Conforms to ISO 13399 tooling data standards for compatibility with CAM and tool management systems

Compatibility

Designed for use in ISCAR Cut-Grip series grooving toolholders accepting the GEPI insert style with size code 200010. Compatible across ISO material groups H, K, M, P, and S per manufacturer specification. Refer to the ISCAR Cut-Grip catalog to confirm holder compatibility before ordering.

Installation Notes

Insert seating and removal should be performed with the machine spindle fully stopped and all power isolated from the machine tool. Use the appropriate ISCAR insert key or extraction tool for the self-grip seat to avoid damaging the insert pocket rails. Inspect the toolholder pocket for wear, burrs, or carbide debris before seating a new insert. Follow the toolholder manufacturer's recommended clamping and indexing procedure to ensure correct seating depth and edge presentation.
