Iscar 6402676 Grooving Insert GIQR8 IC528 Solid Carbide

Product Description

The ISCAR 6402676 is a solid carbide grooving insert in the ChamGroove series, designed for precision external and face grooving operations on CNC turning centers and lathes. It carries the IC528 manufacturer grade with a PVD-applied TiCN and TiN coating finish, delivering wear resistance and edge stability on difficult-to-machine materials. The insert has a right-hand cutting orientation, a 0.1181-inch cutting width, and a maximum depth of cut of 0.051 inches. A corner radius of 0.0059 inches and a positive rake angle of 18 degrees help reduce cutting forces and minimize heat buildup during interrupted or continuous groove passes. Machinists and tooling specialists install this insert in compatible ISCAR ChamGroove toolholders using a clamp-style holding method.

This insert is intended for grooving applications on superalloys and titanium, corresponding to workpiece material codes M, P, and S under ISO 13399 classification. The IC528 grade with PVD coating is well-suited for the elevated temperatures and abrasive conditions common when cutting titanium alloys and nickel-based superalloys in aerospace, medical, and energy-sector components. It fits production environments where consistent groove geometry, tight tolerances, and repeatable insert indexing are required across multi-part runs.

Compatibility

Designed for use in ISCAR ChamGroove series toolholders that accept the GIQR 8-A18-0.15 insert style. Verify toolholder pocket specifications before installation. No additional specific model compatibility data was provided in the product input.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine spindle fully stopped and locked out per applicable safety procedures. Use the correct clamp screw and torque driver recommended for the toolholder system — do not improvise with substitutes. Inspect the insert pocket and clamp for chips or debris before seating the insert to ensure proper contact and accurate positioning. Follow the toolholder manufacturer guidelines for coolant direction and clamping sequence when setting up for superalloy or titanium cuts.
