Iscar 6004549 Cutoff Insert IC908 Carbide 3.05 Mm

Product Description

The ISCAR 6004549 is a solid carbide cutoff and grooving insert in the Tang-Grip series, designed for parting and grooving operations on CNC lathes and turning centers. Manufactured from submicron carbide with an IC908 grade coating applied via PVD process, it delivers consistent edge integrity under demanding cutting conditions. The insert features a 3.05 mm cutting width (0.1200 inches), a neutral lead angle, a neutral hand orientation, and a 7-degree relief angle. A 0.20 mm corner radius and W-style chipbreaker geometry help control chip flow across a wide range of workpiece materials. The insert is held in place by a clamp-style holding method and is rated for single-end use.

This insert is suited for grooving and parting operations in both production and job-shop turning environments. The IC908 grade with PVD coating supports use on universal workpiece materials, including ISO material groups H, K, M, P, and S — covering hardened steels, cast irons, stainless steels, carbon steels, and heat-resistant superalloys. It is compatible with Tang-Grip toolholders designed for this insert series and is a multi-use insert applicable across varying depths and workpiece diameters typical of OD grooving and cutoff work.

Key Features

• IC908 grade PVD-coated submicron carbide construction for extended tool life
• 3.05 mm cutting width (0.1200 inches) for precise groove and parting dimensions
• Neutral lead angle and neutral hand for straightforward setup flexibility
• W-style chipbreaker geometry promotes controlled chip evacuation
• 0.20 mm corner radius minimizes stress concentration at groove walls
• Compatible with ISO material groups H, K, M, P, and S for broad workpiece versatility

Compatibility

Designed for use with Tang-Grip series toolholders that accept TAGN3W insert geometry, as specified by ISCAR for grooving and parting applications across ISO material groups H, K, M, P, and S.

Installation Notes

Installation is performed by a machinist or CNC tooling technician. The machine spindle must be stopped and all motion arrested before seating or removing the insert. Use the appropriate ISCAR Tang-Grip clamping tool to secure the insert fully in the pocket before resuming cuts. Inspect the insert seat and clamping surfaces for chips or debris prior to installation to ensure proper seating and repeatable cutting geometry.
