Iscar 6002399 Cutoff Insert Dgn 6303J IC20 6.35mm

Product Description

The ISCAR 6002399 is a solid carbide cutoff and grooving insert from the Cut-Grip series, carrying the IC20 manufacturer grade. It features a 6.35 mm (0.2500 inch) cutting width and a neutral lead angle, making it suitable for precise parting and grooving operations on a wide range of workpiece materials. The insert uses a self-grip holding method, which simplifies seating in compatible Cut-Grip toolholders. A 0.36 mm corner radius and a 7-degree relief angle contribute to controlled cutting geometry. The insert is uncoated and single-ended. Licensed machinists and toolroom technicians are the typical end users.

This insert is designed for grooving and parting applications across universal workpiece material groups, covering a broad spectrum of metals and non-metals. The ISO material codes H, K, M, N, and S indicate suitability for hardened materials, cast iron, steel, non-ferrous materials, and heat-resistant superalloys. It fits standard Cut-Grip series toolholders that accept the DGN 6303 insert size code. The chipbreaker designation J defines the chip-control geometry for the cutting conditions this insert is engineered to handle. It is built to ISO 13399 standards and carries material grades C2 and C3.

Installation Notes

Insert replacement and seating should be performed by a qualified machinist with the machine powered down and in a locked-out state per applicable lockout/tagout procedures. Ensure the toolholder pocket is clean and free of debris before seating the insert to prevent improper clamping. Do not exceed the cutting parameters recommended for the IC20 grade and the specific workpiece material group. Inspect the self-grip clamping mechanism of the toolholder for wear before installing a new insert.
