Iscar 6004891 Cutoff Insert TAGN3MF IC808 3mm Carbide

Product Description

The ISCAR 6004891 is a Tang-Grip series cutoff and grooving insert designed for precision parting and grooving operations on CNC lathes and turning centers. It features the TAGN3MF insert style with a 3.00 mm (0.1181 inch) cutting width and an IC808 submicron carbide grade finished with a PVD-applied TiN and TiAlN coating. The neutral lead angle and MF chipbreaker geometry support clean chip formation across a broad range of workpiece materials. Machinists and toolroom technicians install this insert into compatible Tang-Grip toolholders as a single-end, self-gripping insert.

This insert is suited for grooving and parting applications across universal workpiece material groups, including ISO material codes H, K, M, P, and S. That coverage spans hardened materials, cast iron, stainless and general steels, and heat-resistant superalloys. It performs in both high-production and job-shop turning environments where repeatable insert seating and consistent cutting width are required. The MF chipbreaker targets medium-finish cutting conditions, making it a practical choice for light to moderate feeds and depths of cut.

Key Features

• IC808 submicron solid carbide grade with PVD TiN and TiAlN coating for wear resistance and toughness
• 3.00 mm (0.1181 inch) cutting width with a 0.20 mm (0.0079 inch) corner radius
• Neutral lead angle and neutral hand orientation for versatile setup
• MF chipbreaker geometry promotes controlled chip evacuation on finish-to-medium cuts
• Self-grip insert holding method for positive, repeatable seating in Tang-Grip toolholders
• Multi-use rated for both grooving and parting operations

Compatibility

Designed for use in ISCAR Tang-Grip series toolholders that accept TAG-style inserts with a size code 3 profile. Compatible across ISO material groups H, K, M, P, and S as stated in manufacturer data. Verify toolholder series and insert pocket dimensions before ordering.

Installation Notes

Installation is performed by machinists or toolroom technicians on powered-off and locked-out turning equipment. The self-gripping Tang-Grip design requires no additional clamping hardware; insert the tang fully into the toolholder pocket until seated. Inspect the insert pocket for chips or debris before seating a new insert to ensure accurate cutting width presentation. Follow the machine manufacturer and toolholder manufacturer guidelines for maximum depth of cut and feed rate for this insert size.
