Iscar 6200307 HFPR4020 IC808 Grooving Insert 4mm Right Hand

Product Description

The ISCAR 6200307 is a solid carbide grooving insert carrying the HFPR4020 designation and IC808 manufacturer grade, designed for precision grooving operations on CNC turning centers and lathes. It features a 4 mm (0.1575 inches) cutting width and a maximum depth of cut of 2 mm (0.0787 inches), with a full corner radius of 2 mm. The insert is double-ended, extending tool life between index changes. A PVD-applied AlTiN, TiAlN, and TiN multilayer coating delivers heat resistance and wear protection across a wide range of workpiece materials. The IC808 submicron carbide grade is engineered for consistent performance under interrupted cuts and varying feed conditions. Licensed machinists and CNC tool setters are the primary users of this insert.

This insert belongs to the ISCAR Heliface series and is suited for external grooving and profiling applications on turning and mill-turn equipment. Its positive 7-degree rake angle reduces cutting forces, making it appropriate for both roughing and finishing passes. The universal primary workpiece material classification means it is applicable across steel, stainless steel, cast iron, aluminum alloys, and high-temperature superalloys, covering ISO material groups P, M, K, H, and S. It is used in production environments where tight groove tolerances and surface finish consistency are required.

Key Features

• Solid carbide HFPR-style insert with IC808 submicron carbide grade for extended tool life
• PVD coating combining AlTiN, TiAlN, and TiN layers for thermal resistance and low friction
• Full corner radius of 2 mm (0.0787 inches) for profiling and groove bottom finishing
• Double-ended design provides two usable cutting edges per insert
• Positive rake angle of 7 degrees reduces cutting forces on the workpiece
• Compatible with universal workpiece materials across ISO groups P, M, K, H, and S

Compatibility

Designed for use with ISCAR Heliface series grooving toolholders that accept HFPR-style inserts with a 4020 insert size code. Consult the ISCAR toolholder selection guide to confirm clamp and pocket compatibility before installation.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist or CNC tool setter following the toolholder manufacturer's torque and clamp specifications. Power down and lock out the machine before changing inserts. Inspect the insert pocket for debris or wear before seating the new insert. Verify insert orientation for right-hand cutting direction before resuming operation.
