Iscar 6403370 GEPI250010 IC528 Grooving Insert 2.5mm

Product Description

The ISCAR 6403370 is a solid carbide grooving insert from the Cut-Grip series, designed for precision grooving and parting operations on CNC lathes and turning centers. Carrying the IC528 manufacturer grade with a PVD-applied TiCN and TiN coating, this double-ended insert delivers a 2.5 mm cutting width and a maximum depth of cut of 9 mm. The positive rake geometry at 8 degrees reduces cutting forces and heat buildup, making it well suited for demanding workpiece materials. Licensed machinists and CNC turning technicians install this insert as a direct replacement in compatible Cut-Grip toolholders.

This insert is intended for grooving and parting applications in industrial turning environments, both production-floor and job-shop settings. Its primary workpiece material ratings cover superalloys, titanium, and steel, corresponding to ISO material codes M, P, and S. The neutral hand orientation and clamp-style holding method suit a wide range of standard Cut-Grip system toolholders. The double-ended design provides two cutting edges per insert, reducing per-edge tooling cost in high-volume grooving operations.

Key Features

• Solid carbide construction with PVD TiCN and TiN coating for wear resistance on superalloys and titanium
• 2.5 mm cutting width with a maximum depth of cut of 9 mm
• Positive rake angle of 8 degrees reduces cutting forces and tool pressure
• Double-ended design yields two usable cutting edges per insert
• Corner radius of 0.10 mm (0.0039 inches) for tight-tolerance groove profiles
• Clamp-style insert holding for secure, repeatable seating in Cut-Grip toolholders
• Compliant with ISO 13399 tooling data standards

Compatibility

Designed for use in ISCAR Cut-Grip series clamping toolholders that accept the GEPI insert style with size code 250010. Rated for maximum depth of cut range of 5 mm to 10 mm (0.3000 to 1.0000 inches). Compatible with workpiece materials classified under ISO codes M, P, and S, including superalloys, titanium, and steel.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC tooling technician with the machine in a full stop, lockout/tagout state. Use the appropriate clamp key or torx wrench specified by the toolholder manufacturer to seat the insert securely — do not overtighten the clamp screw. Inspect the insert pocket for chips or debris before seating each new edge. Verify insert orientation and edge engagement before resuming cutting operations.
