Iscar 6403329 Grooving Insert GEPI100010 IC908 1mm Cut-grip

Product Description

The ISCAR 6403329 is a solid carbide grooving insert in the Cut-Grip series, designed for precision grooving operations on CNC lathes and turning centers. The insert carries ISCAR grade IC908 with a PVD-applied TiAlN coating, which provides hardness and wear resistance across a broad range of workpiece materials. It features a 1.00 mm cutting width and a maximum depth of cut of 1.60 mm, making it well suited for narrow, precise grooves in tight-tolerance applications. The double-ended design extends usable tool life per insert. This insert is installed and used by machinists and CNC tooling technicians working in production and job-shop environments.

The ISCAR 6403329 is intended for grooving, parting, and face grooving operations where consistent dimensional accuracy is required. Its IC908 grade with TiAlN coating supports use on universal workpiece materials, covering ISO material groups H, K, M, P, and S. This includes steel, stainless steel, cast iron, hardened materials, and heat-resistant superalloys. The self-grip insert holding method provides secure seating in compatible Cut-Grip toolholders without additional clamping hardware, which suits high-volume and automated turning setups.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Before changing inserts, ensure the machine spindle is fully stopped and the machine is placed in a safe, locked-out state per shop safety procedures. Use proper insert handling tools to avoid contact with cutting edges. Verify that the toolholder pocket is clean and free of chips or debris before seating the insert to ensure proper grip and runout.
