Iscar 6094007 GFN3B IC328 Carbide Cutoff Insert 3.02mm

Product Description

The ISCAR 6094007 is a solid carbide cutoff and grooving insert in the GFN3B configuration, designed for precision parting and grooving operations on CNC lathes and turning centers. It carries the IC328 grade, a PVD-coated carbide formulation optimized for cutting superalloys and a broad range of ferrous and non-ferrous workpiece materials. The insert delivers a 3.02 mm (0.1189 inch) cutting width with a neutral lead angle and a 7-degree relief angle. A 0.30 mm corner radius reduces edge chipping at cut entry and exit. It is held by a clamp-style toolholder in the ISCAR Self-Grip series and is rated for single-end use.

This insert is suited for production turning environments where tight groove-width tolerances and clean parting cuts are required. Primary applications include grooving and parting on superalloy, steel, and other ISO-coded M, P, and S workpiece materials. The B chipbreaker geometry promotes reliable chip evacuation in interrupted and continuous cuts. It is compatible with Self-Grip series toolholders that accept a size-3 insert seat, making it a practical choice for job shops and high-volume turning operations alike.

Key Features

• IC328 PVD-coated carbide grade optimized for superalloy and steel cutting
• 3.02 mm (0.1189 inch) cutting width for consistent groove dimensions
• Neutral lead angle and 7-degree relief angle reduce lateral cutting forces
• 0.30 mm corner radius for improved edge durability at groove entry
• B chipbreaker geometry supports controlled chip formation and evacuation
• Clamp-held in Self-Grip series size-3 toolholders for rigid, repeatable seating

Compatibility

Designed for use with ISCAR Self-Grip series toolholders that accept a size-3 insert seat. Suitable for workpiece materials classified under ISO material codes M, P, and S, including superalloys, steels, and stainless steels. Conforms to ISO 13399 insert identification standards.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Disengage machine power and confirm the spindle is fully stopped before seating or removing inserts. Use the correct ISCAR clamping key to seat the insert fully against the toolholder pocket walls before torquing the clamp screw. Inspect the insert seat for chips or debris prior to installation to ensure accurate seating and prevent premature edge failure.
