Iscar 6200341 Grooving Insert HFPR4004 IC8250 4mm

Product Description

The ISCAR 6200341 is a solid carbide grooving insert in the Heliface series, designed for precision external grooving and parting operations on CNC lathes and turning centers. The insert carries the HFPR4004 style designation and is finished with an Al2O3 PVD coating under the IC8250 manufacturer grade. It delivers a 4 mm cutting width with a maximum depth of cut ranging from 2 mm to 3 mm. The positive rake angle of 7 degrees and 0.40 mm corner radius make it well suited for clean chip formation on stainless steel and general steel workpieces. Installation requires a compatible Heliface clamp-style toolholder.

This insert is intended for right-hand cutting applications on turning and grooving operations in both production and job-shop environments. Primary target workpiece materials are stainless steel and steel, covering ISO material codes M and P. The double-end configuration allows both ends of the insert to be indexed, extending usable tool life before replacement. Machinists and CNC lathe operators working on tight-tolerance groove profiles will find the fixed geometry and consistent PVD coating beneficial for repeatable results across production runs.

Key Features

• 4 mm cutting width with a maximum depth of cut range of 2 mm to 3 mm
• IC8250 grade with Al2O3 PVD coating for wear resistance on steel and stainless steel
• Positive rake angle of 7 degrees promotes efficient chip evacuation and reduced cutting forces
• Double-end insert design provides two usable cutting edges per insert
• 0.40 mm corner radius for controlled groove profile geometry
• Clamp-style insert holding method compatible with Heliface series toolholders

Compatibility

Designed for use with ISCAR Heliface series clamp-style grooving toolholders that accept the HFPR4004 insert size. Confirm toolholder pocket specifications before installation.

Installation Notes

Insert installation should be performed by a qualified machinist or CNC tooling technician. Always power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate torque wrench and clamp screw specified by the toolholder manufacturer — do not overtighten the clamp, as this can fracture the carbide insert. Inspect the toolholder pocket for chips or debris before seating the new insert to ensure proper contact and geometry alignment.
