Iscar 6000424 Cutoff Insert Gfr 2.4 4D IC20 Carbide

Product Description

The ISCAR 6000424 is a solid carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. It carries the manufacturer catalog designation GFR 2.4-4D and is manufactured to ISO 13399 standards. The insert features a 2.40 mm (0.0945 inch) cutting width, a 4-degree right-hand lead angle, a 7-degree relief angle, and a 0.16 mm corner radius. Finished in an uncoated state, it is rated for universal workpiece material compatibility across ISO material groups H, K, M, N, and S. This insert is installed by machinists and tooling technicians in production and job-shop turning environments.

This insert belongs to ISCAR's Self-Grip series and is intended for single-ended cutoff and parting applications. It seats using a clamp-style holding method, making it compatible with Self-Grip toolholders designed for GFR-style inserts. The right-hand orientation and 4-degree lead angle suit standard OD cutoff work on bar stock and turned components. Typical applications include production parting on steel, cast iron, aluminum, non-ferrous alloys, and superalloys, consistent with its H, K, M, N, and S material group ratings. It is sold individually with a minimum order quantity of 10 units.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before seating or replacing any insert. Ensure the toolholder pocket and clamping surfaces are clean and free of chips before installing the insert. Follow the toolholder manufacturer's clamping procedure and inspect the insert seating before resuming cutting operations.
