Iscar 6002573 Cutoff Insert Gfn 3 IC328 3.03mm

Product Description

The ISCAR 6002573 is a single-end carbide cutoff and grooving insert designed for precision parting and grooving operations on CNC lathes and turning centers. It carries the IC328 PVD-coated carbide grade, a coating process suited for maintaining sharp edges and resisting built-up edge on difficult materials. The insert features a 3.03 mm (0.1193 inch) cutting width, a neutral lead angle, a 7-degree relief angle, and a 0.20 mm corner radius. It belongs to ISCAR's Self-Grip insert series and is sized to seat in an Insert Seat Size 3 toolholder. Installation and application are appropriate for experienced machinists and tooling technicians working in production turning environments.

This insert is rated for primary application in grooving and parting operations, with a primary workpiece material designation of Superalloy, corresponding to ISO material codes M, P, and S. Superalloy cutting demands a tough, wear-resistant substrate with a reliable PVD coating to manage heat and maintain edge integrity at the cutting zone. The IC328 grade with PVD finish is engineered for these conditions. The C chipbreaker geometry supports chip control across a range of feed rates typical in grooving work. This insert is cataloged under ISO 13399 standards and carries material grades C2, C3, C5, and C6.

Key Features

• 3.03 mm (0.1193 inch) cutting width for precise groove and parting dimensions
• IC328 PVD-coated carbide grade optimized for superalloy and difficult-material applications
• Neutral lead angle and 7-degree relief angle for balanced cutting forces
• 0.20 mm corner radius with C chipbreaker geometry for controlled chip evacuation
• Self-Grip series clamping method for secure, repeatable insert seating
• ISO 13399 compliant — integrates with compatible tooling data systems

Compatibility

Designed as an OEM-style replacement insert for ISCAR Self-Grip series toolholders accepting an Insert Seat Size 3 and GFN-style insert geometry. Confirm toolholder seat size and insert style code before ordering.

Installation Notes

Insert installation and replacement should be performed by a qualified machinist or tooling technician with the machine in a fully stopped and locked-out state. Use the appropriate ISCAR torx or hex key to the toolholder manufacturer's specified seating procedure — do not overtighten clamping screws. Inspect the insert pocket and clamping surfaces for chips or debris before seating a new insert. Verify correct insert orientation relative to the workpiece centerline before resuming cutting operations.
