Iscar 6402789 Grooving Insert Giff IC908 Solid Carbide

Product Description

The ISCAR 6402789 is a solid carbide grooving insert in the GIF insert style, part of the Cut-Grip series. It carries an IC908 manufacturer grade with a TiAlN finish applied via PVD coating process. The insert features a positive rake angle of 7 degrees and a corner radius of 0.0157 inches (0.40 mm), making it suited for precision grooving and parting operations on CNC turning centers and lathes. The F chip breaker geometry promotes controlled chip flow. This insert is sold individually but requires a minimum order of 10 units.

The 6402789 is designed for universal workpiece material compatibility, covering ISO material groups H, K, M, P, and S. This range includes hardened steels, cast irons, stainless steels, carbon and alloy steels, and high-temperature superalloys. It fits typical production turning environments where consistent groove geometry and reliable chip control are required. The Cut-Grip series is a widely used grooving platform for both external and face grooving applications in general machining operations.

Key Features

• Positive rake angle of 7 degrees reduces cutting forces and improves chip flow
• Corner radius of 0.0157 inches (0.40 mm) for accurate groove profiles
• F chip breaker geometry for controlled chip formation
• Maximum depth of cut of 13.00 mm
• Multi-use tool compatible with H, K, M, P, and S ISO material groups

Compatibility

Designed as an OEM-style replacement insert for Cut-Grip series grooving toolholders. Confirm insert style code GIF and size code 400E040 match your toolholder specification before installation.

Installation Notes

Grooving inserts of this type are installed and replaced by machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or removing the insert. Use the correct torque wrench and clamping hardware specified by the toolholder manufacturer — do not substitute fasteners. Inspect the insert seat and clamping components for wear or debris before each insert change to ensure proper seating and repeatable tool geometry.
