Iscar 6403919 Grooving Insert IC528 Solid Carbide 3mm

Product Description

The ISCAR 6403919 is a solid carbide grooving insert from the ChamGroove series, designed for precision external grooving and parting operations on CNC turning centers and lathes. This right-hand insert carries the GIQR1115300R150 form factor and is finished with a PVD-applied TiCN and TiN coating for improved wear resistance and edge stability. The IC528 grade is engineered for demanding cutting conditions. Key cutting parameters include a 3.00 mm cutting width, a maximum depth of cut of 6.30 mm, and a full corner radius of 1.50 mm. The insert measures 14.60 mm overall length and is secured via screw clamping.

This insert is suited for grooving and profiling operations in both production and job-shop turning environments. Primary workpiece materials include superalloys and titanium, with ISO material codes M, P, and S, making it applicable across a broad range of ferrous and non-ferrous aerospace and industrial components. The screw-holding method provides rigid clamping and repeatable edge location, which is critical when maintaining tight tolerances in groove width and depth. It is a single-end insert and is multi-use capable across compatible ChamGroove toolholders.

Compatibility

Designed for use with compatible ChamGroove series toolholders that accept the GIQR insert style and 1115300R150 insert size. Verify toolholder specification against the GIQR seat geometry before installation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine in a locked-out, zero-energy state. Use the specified screw-clamping hardware for the toolholder seat; do not substitute fasteners. Inspect the insert pocket and seating surfaces for chips or debris before seating the insert. Follow the toolholder manufacturer torque guidance for the clamping screw to avoid insert cracking or seat damage.
