Iscar 6002541 Gfn 3J IC-328 Carbide Cutoff Insert 3mm

Product Description

The ISCAR 6002541 is a solid carbide cutoff and grooving insert designed for precision parting and grooving operations on CNC lathes and turning centers. It carries the GFN insert style with a 3 mm cutting width (0.1181 inches) and a J-style chipbreaker geometry suited for controlled chip evacuation. The IC-328 grade features a PVD coating applied over a carbide substrate, making it particularly well-suited for machining superalloys and other demanding workpiece materials. A neutral lead angle and 7-degree relief angle support straight, repeatable cuts with minimal lateral loading on the tool holder.

This insert is part of the ISCAR Self-Grip series and is intended for grooving and parting applications in production turning environments. The IC-328 grade targets superalloy workpieces (ISO material codes M, P, and S) and is rated for material grades C2, C3, C5, and C6. It is a single-end insert secured by clamp-style holding, making it compatible with Self-Grip toolholders that accept a size 3 insert seat. Typical users include CNC machinists and toolroom technicians working in aerospace, energy, and general precision-machining environments.

Key Features

• 3 mm cutting width (0.1181 inches) for precise parting and grooving cuts
• IC-328 PVD-coated carbide grade optimized for superalloy and multi-material applications
• J-style chipbreaker geometry promotes controlled chip flow during interrupted and continuous cuts
• Neutral lead angle with 7-degree relief angle for straight, low-force entry
• 0.25 mm corner radius (0.0098 inches) for clean groove geometry and reduced corner stress
• Conforms to ISO 13399 standards for tool data representation and system compatibility

Compatibility

Designed for use with ISCAR Self-Grip series toolholders that accept a size 3 insert seat and clamp-style insert retention. Compatible with workpiece material grades C2, C3, C5, and C6 per ISO classification.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Power down and lock out the machine spindle before seating or replacing any turning insert. Ensure the insert pocket and clamping surfaces are clean and free of chips before seating the insert. Verify clamp torque and insert seating per the toolholder manufacturer specifications before resuming cutting operations.
