Iscar 6200070 HFPR4020 IC354 Grooving Insert 4mm

Product Description

The ISCAR 6200070 is a solid carbide grooving insert in the Heliface series, designed for precision external grooving and parting operations on CNC lathes and turning centers. It carries the HFPR4020 insert style designation with an IC354 grade and a TiCN PVD coating. The cutting width is 4.00 mm (0.1575 inches) with a maximum depth of cut of 2.00 mm (0.0787 inches) and a full corner radius of 2.00 mm (0.0790 inches). The positive rake angle of 7 degrees promotes free cutting action and reduced cutting forces. This insert is suited for high-production turning environments where surface finish and dimensional accuracy are critical.

The 6200070 is rated for use on stainless steel and steel workpiece materials, corresponding to ISO material codes M and P. Its double-end configuration allows both cutting edges to be used, extending insert life and reducing tooling cost per part. The Heliface series is typically deployed in medium to high-volume turning applications on modern CNC equipment. The right-hand cutting orientation and 0-degree lead angle make this insert compatible with standard axial grooving tool holders in the HFPR family.

Key Features

• Solid carbide construction with IC354 grade for wear resistance on steel and stainless steel
• TiCN PVD coating provides a hard, low-friction surface suitable for finishing cuts
• Full radius insert (corner radius 2.00 mm) for smooth groove floor geometry
• Double-end insert — both cutting edges usable, maximizing insert value
• Positive rake angle (7 degrees) reduces cutting forces and heat generation
• Conforms to ISO 13399 tooling data standards for CAM and tool management integration

Compatibility

Designed for use with ISCAR Heliface series HFPR-style grooving tool holders. Compatible with workpiece materials classified as ISO P (steel) and ISO M (stainless steel). Insert size code 4020 corresponds to 4.00 mm cutting width and the 20 mm holder pocket size within the Heliface system.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or removing inserts. Use the appropriate torx or clamping key specified for the tool holder to secure the insert — do not overtighten or use improvised tools that could damage the insert pocket. Verify insert orientation and hand designation match the tool holder before resuming operation.
