Iscar 6004781 Cutoff Insert IC908 Carbide 3mm Grooving

Product Description

The ISCAR 6004781 is a solid carbide cutoff and grooving insert from the PentaCut series, identified by the manufacturer catalog designation PENTA 24N300C020 and grade IC908. The insert features a 3.00 mm (0.1181 inch) cutting width and a 0.20 mm corner radius, with a neutral lead angle and neutral hand orientation. The IC908 grade uses a submicron carbide substrate with a PVD-applied TiN and TiAlN coating, making it suitable for a broad range of workpiece materials. Installation is performed by screw clamping. This insert is used by machinists and toolroom professionals in CNC turning and lathe operations.

This insert is designed for grooving and parting operations across universal workpiece material groups, including ISO material codes H, K, M, P, and S, covering steels, stainless steels, cast irons, hardened materials, and heat-resistant superalloys. The PentaCut series is widely applied in production turning environments where consistent groove width, clean parting cuts, and reliable edge life are required. The screw-lock holding method keeps the insert seated under the interrupted and continuous cutting loads common to parting and grooving cycles.

Installation Notes

This insert is installed and removed by a licensed machinist or qualified toolroom technician. Power down and lock out the machine spindle before changing inserts. Use the correct ISCAR torx or hex key to tighten the clamping screw to the toolholder manufacturer's specified procedure — do not overtighten or substitute fasteners. Confirm insert seating is flush and the screw is fully engaged before resuming cutting operations.
