Iscar 6004959 DGN4003MF IC808 Carbide Cutoff Insert

Product Description

The ISCAR 6004959 is a solid carbide cutoff and grooving insert in the Do-Grip series, offered in the DGN4003MF geometry with IC808 manufacturer grade. It carries a PVD-applied multilayer coating of TiAlN, AlTiN, and TiN for wear resistance across a broad range of workpiece materials. The insert features a neutral hand and neutral lead angle, a 0.012 inch corner radius, and an MF chipbreaker profile suited to finish and medium grooving operations. Overall length is 0.74 inches. This insert is installed by machinists and tooling technicians on CNC turning centers and manual lathes performing grooving and parting operations.

The DGN4003MF IC808 insert is designed for grooving and parting applications in a universal material range, making it suitable for use on ferrous metals, stainless steels, cast irons, aluminum alloys, and superalloys. The IC808 grade with PVD coating performs well in interrupted cuts and general-purpose turning center environments. Maximum depth of cut is 1.181 inches, supporting a wide variety of groove depths in production and job-shop settings.

Compatibility

Designed for use in ISCAR Do-Grip series toolholders that accept DGN-style inserts with a 4003 size code. Compatible with workpiece material codes H, K, M, P, and S per ISO classification, covering hardened materials, cast irons, stainless steels, steels, and superalloys.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. The machine spindle must be fully stopped and locked out before seating or removing the insert. Use the correct torx or clamping key specified for the Do-Grip toolholder to secure the insert without over-torquing the clamping screw. Verify insert seating and clamp integrity before resuming cutting operations.
