Iscar 6290254 Grooving Insert HFPR5004 IC428 5mm Heliface

Product Description

The ISCAR 6290254 is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. Cataloged under the Heliface series with insert style HFPR and size code 5004, this double-ended insert delivers a 5.00 mm (0.1969 inch) cutting width and a maximum depth of cut of 2.50 mm (0.0984 inch). The IC428 grade combines a CVD-applied Al2O3 and TiC coating with a positive 7-degree rake angle, targeting demanding materials including steel, cast iron, and hard materials. Licensed machinists and CNC tooling technicians specify this insert for consistent groove geometry and extended tool life in high-volume turning applications.

This insert is suited for use in residential machine shops, job shops, and production environments where tight groove tolerances are required. The right-hand orientation and double-end configuration make it compatible with ISCAR Heliface series toolholders designed for the HFPR 5004 insert pocket. Primary workpiece materials include steel (ISO P), cast iron (ISO K), and hard materials (ISO H), covering a broad range of common turning applications. No full radius is ground on this insert; the corner radius measures 0.40 mm (0.0157 inch).

Key Features

• 5.00 mm cutting width with maximum depth of cut up to 2.50 mm for consistent groove sizing
• IC428 grade with CVD Al2O3 and TiC coating for wear resistance on steel, cast iron, and hard materials
• Positive 7-degree rake angle reduces cutting forces and improves chip flow
• Double-end design extends usable insert life before replacement
• Right-hand cutting orientation for standard lathe configurations
• Compliant with ISO 13399 tooling data standards for CAM and tool management integration

Compatibility

Designed for use in ISCAR Heliface series toolholders accepting the HFPR 5004 insert style. Suitable for machining steel (ISO P), cast iron (ISO K), and hard materials (ISO H) with material grades C3 and C4. Verify toolholder pocket geometry and clamping style before installation.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before changing inserts. Seat the insert fully into the pocket and confirm the clamping screw is tightened to the toolholder manufacturer specification before resuming cuts. Inspect the insert pocket and clamping mechanism for wear or debris before each insert change.
