Iscar 6002574 Gfn 4 IC328 Carbide Cutoff Insert 4.05mm

Product Description

The ISCAR 6002574 is a carbide cutoff and grooving insert designed for precision parting and grooving operations on CNC lathes and turning centers. It carries the IC328 manufacturer grade with a PVD coating, making it well suited for cutting superalloys and other demanding workpiece materials. The insert features a 4.05 mm (0.1594 inch) cutting width, a neutral lead angle, and a 7-degree relief angle. A 0.24 mm corner radius and integrated C-style chipbreaker support controlled chip evacuation during deep grooving and parting cuts. The Self-Grip series holding method secures the insert in the toolholder without additional fasteners, reducing setup time in high-volume turning applications.

This insert is intended for grooving and parting applications in metalworking environments, including aerospace and general precision machining where superalloy components are common. It is a single-end insert, meaning it is replaced rather than reversed when the cutting edge is spent. The IC328 grade with PVD coating is rated for material grades C2, C3, C5, and C6, covering a range of steel, stainless, and superalloy workpieces. It is installed by machinists and CNC setup technicians working with compatible Self-Grip toolholders.

Key Features

• IC328 grade PVD-coated carbide for extended tool life on superalloys and steels
• 4.05 mm (0.1594 inch) cutting width with a neutral lead angle for straight parting cuts
• 7-degree relief angle reduces rubbing and heat buildup at the cutting edge
• C-style chipbreaker promotes chip control in grooving and parting operations
• Self-Grip clamping method allows fast, secure insert indexing without separate clamp hardware
• Conforms to ISO 13399 tooling data standards for compatibility with digital tool management systems

Compatibility

Designed for use with ISCAR Self-Grip series toolholders that accept GFN style inserts with an insert seat size of 3. Confirm toolholder specifications before ordering.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the turret is in a safe index position before changing inserts. Seat the insert fully into the Self-Grip toolholder pocket and verify secure clamping before resuming cuts. Do not exceed the toolholder manufacturer's recommended depth-of-cut or feed rate for this insert style.
