Iscar 6402140 Grooving Insert GIM4W IC328 Ticn

Product Description

The ISCAR 6402140 is a solid carbide grooving insert from the Cut-Grip series, designed for precision grooving and parting operations on CNC lathes and turning centers. The insert carries the IC328 manufacturer grade and a PVD-applied TiCN coating, which improves surface hardness and wear resistance at the cutting edge. It features a neutral hand orientation, a 0.1575-inch (4.00 mm) cutting width, and a positive rake angle of 7 degrees that reduces cutting forces. With a W-style chip breaker geometry and a GIM insert style, this insert is suited for controlled chip evacuation in demanding turning applications. Licensed machinists and CNC operators install and index this insert.

This insert is intended for grooving operations on superalloy and titanium workpieces, corresponding to ISO material codes M, P, and S. It is a single-end insert with an insert seat size of 4, an overall length of 0.6024 inches, and a corner radius of 0.0098 inches (0.25 mm). Typical applications include groove turning, face grooving, and cut-off work on production turning equipment where tight tolerance and surface finish are required. The IC328 grade and TiCN PVD coating make it especially effective in difficult-to-machine alloy materials.

Key Features

Compatibility

Designed for use with Cut-Grip series toolholders that accept a size 4 insert seat and GIM-style inserts. Confirm toolholder insert seat dimensions before installation.

Installation Notes

Insert indexing and replacement should be performed by a qualified machinist or CNC operator with the machine fully stopped and locked out per applicable safety procedures. Use the correct torque wrench and clamping screw specified by the toolholder manufacturer when seating the insert. Inspect the insert pocket and clamping mechanism for wear or debris before installing a new insert. Do not attempt to regrind or modify this insert.
