Iscar 6290555 Grooving Insert HFPR4004 IC328 Ticn 4mm

Product Description

The ISCAR 6290555 is a solid carbide grooving insert from the Heliface series, designed for precision grooving and parting operations on CNC turning centers and lathes. It carries an IC328 grade with a PVD-applied TiCN coating, delivering wear resistance and thermal stability at the cutting edge. The insert features a 4.00 mm cutting width, a maximum depth of cut of 2.00 mm, and a 0.40 mm corner radius. The double-ended configuration provides two usable cutting edges per insert. Right-hand orientation and a 7-degree positive rake angle promote efficient chip flow and reduced cutting forces. Machining professionals working with difficult-to-cut materials specify this insert for its consistent edge integrity under demanding conditions.

This insert is engineered for grooving, undercutting, and light parting in materials classified under ISO material groups M, P, and S, with primary workpiece materials listed as superalloys and titanium. Its double-end geometry suits high-production turning applications where tool change frequency directly affects cycle time. The Heliface series insert design is intended for use in compatible ISCAR Heliface toolholders and grooving systems used in both aerospace and general precision machining environments. ISCAR-style grooving inserts in this class are typically installed by CNC machinists and toolroom technicians.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Ensure the machine spindle is fully stopped and all power is off before changing inserts. Seat the insert firmly and evenly into the toolholder pocket using the appropriate torx or clamping key specified by the toolholder manufacturer. Do not exceed the rated maximum depth of cut for this insert style, and inspect the cutting edge for chipping before each use.
