Iscar 6004697 Cutoff Insert 1.6mm Tang-grip IC808 Carbide

Product Description

The ISCAR 6004697 is a solid carbide cutoff and grooving insert designed for precision parting and grooving operations on CNC lathes and turning centers. Part of the Tang-Grip series, it features a 1.6 mm (0.0630 inch) cutting width and a neutral lead angle with neutral hand orientation, making it suitable for straight radial cuts. The IC808 grade combines a fine-grain carbide substrate with a PVD-applied TiAlN, AlTiN, and TiN multilayer coating, delivering strong wear resistance and edge integrity across a broad range of workpiece materials. A licensed machinist or toolroom technician typically specifies and installs this insert.

This insert is rated for universal primary workpiece material compatibility, covering ISO material groups H, K, M, P, and S. That range includes carbon and alloy steels, stainless steels, cast irons, non-ferrous alloys, and high-temperature superalloys. The J chipbreaker geometry promotes controlled chip formation during grooving and parting passes, reducing the risk of chip packing in narrow grooves. It is a single-end insert, meaning one cutting edge per insert, and the Tang-Grip tang seating system ensures positive, repeatable insert location in compatible Tang-Grip toolholders.

Key Features

• 1.6 mm (0.0630 inch) cutting width for narrow grooving and parting applications
• IC808 grade with PVD coating: TiAlN, AlTiN, and TiN layers for extended tool life
• Fine-grain solid carbide substrate provides toughness and edge stability
• Neutral lead angle and neutral hand for straight radial cut geometry
• J chipbreaker promotes controlled chip evacuation in confined groove profiles
• Universal material compatibility across ISO groups H, K, M, P, and S

Compatibility

Designed for use in ISCAR Tang-Grip series toolholders that accept TAG-style inserts with a 1.6 mm insert size code. Confirm toolholder bore and tang slot dimensions against ISCAR Tang-Grip toolholder specifications before ordering.

Installation Notes

Insert seating and replacement should be performed by a qualified machinist or toolroom technician with the machine fully stopped and all axes locked out per facility LOTO procedures. Inspect the Tang-Grip pocket for debris or wear before seating the new insert, and confirm secure tang engagement before resuming cuts. Do not exceed the toolholder or machine manufacturer's recommended depth-of-cut or feed parameters for this insert width.
