Iscar 6003289 DGNM3202J IC328 Carbide Cutoff Insert

Product Description

The ISCAR 6003289 is a solid carbide cutoff and grooving insert from the Do-Grip series, offered in the DGNM3202J style with an IC328 manufacturer grade. It delivers a 3.18 mm (0.1250 inch) cutting width and a 0-degree neutral lead angle, making it well suited for precise parting and grooving operations. The insert features a PVD-applied TiN and TiCN coating over solid carbide substrate, providing wear resistance and thermal stability during aggressive cuts. The J chipbreaker geometry and a 0.20 mm corner radius support controlled chip formation. This insert is installed by machinists and toolroom professionals working on CNC turning and machining centers.

The ISCAR 6003289 is designed for grooving and parting applications where dimensional accuracy and tool life are critical. Its primary workpiece material rating targets superalloys, along with ISO material groups M, P, and S, covering stainless steels, carbon and alloy steels, and heat-resistant alloys. The single-end configuration and clamp holding method allow it to seat securely in compatible Do-Grip toolholders. It is appropriate for both light finishing passes and moderate material removal in a turning center environment.

Key Features

• Solid carbide construction with IC328 grade for high hardness and wear resistance
• PVD-applied TiN and TiCN coating for thermal protection and extended edge life
• 3.18 mm cutting width with a 0.20 mm corner radius for accurate groove geometry
• Neutral lead angle and J chipbreaker for controlled chip evacuation
• Rated for superalloys and ISO material groups M, P, and S
• Clamp-style insert holding for rigid, repeatable seating in Do-Grip toolholders

Compatibility

Designed for use with ISCAR Do-Grip series toolholders that accept the DGNM 3202 insert style. Suitable for turning centers and CNC lathes performing grooving and parting operations on superalloys, stainless steels, and carbon and alloy steels.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before seating or replacing the insert. Use the appropriate ISCAR Do-Grip clamping mechanism to secure the insert fully before resuming cuts. Inspect the insert seating pocket for chips or debris prior to installation to ensure full contact and accurate positioning.
