Iscar 6094235 Gfn 2.4 IC328 Carbide Cutoff Grooving Insert

Product Description

The ISCAR 6094235 is a solid carbide cutoff and grooving insert in the GFN 2.4 configuration, manufactured to the IC328 grade with a PVD coating. It carries a 2.4 mm (0.0945 inch) cutting width and is designed for use in Self-Grip toolholding systems, where the insert is secured by a clamping mechanism rather than a screw. The neutral lead angle and neutral hand orientation make it adaptable to straight plunge grooving and parting operations. With a 7-degree relief angle and a 0.16 mm corner radius, it delivers clean entry geometry suited to precision cutoff work on difficult materials. Licensed machinists and CNC turning specialists install and index this insert as part of routine tooling maintenance.

This insert is rated for superalloy workpiece materials and carries primary workpiece material codes M, P, and S under ISO 13399, covering steel, stainless steel, and superalloy classifications. It is suited to grooving and parting applications on CNC lathes and turning centers where precise groove width control is critical. The PVD-coated IC328 grade provides the wear resistance and edge toughness required when cutting heat-resistant alloys at moderate to high surface speeds. The single-end configuration means one cutting edge per insert.

Key Features

• Solid carbide construction with PVD-coated IC328 grade for extended tool life in superalloy cutting
• 2.4 mm cutting width for precise groove and parting dimensions
• Neutral lead angle and neutral hand for straight plunge grooving without lateral cutting force bias
• 7-degree relief angle reduces flank contact during grooving passes
• 0.16 mm corner radius for controlled groove-bottom geometry
• Self-Grip series compatibility — clamped retention, no screw required
• Meets ISO 13399 tooling data standards for system integration

Compatibility

Designed for use with ISCAR Self-Grip series toolholders and blade-style grooving systems that accept GFN-style inserts. Compatible with workpiece material grades C2, C3, C5, and C6. Refer to the ISCAR Self-Grip catalog to confirm the correct blade or holder for the target groove depth and machine interface.

Installation Notes

Installation and indexing should be performed by a qualified machinist or tooling technician with the machine in a safe, powered-down state and the spindle locked. Seat the insert fully into the Self-Grip pocket before clamping to ensure proper engagement and repeatable cutting-edge position. Inspect the insert seat and clamping surfaces for chips or debris before each index. Follow the toolholder manufacturer torque and clamping guidelines for the specific blade or holder in use.
