Iscar 6402802 GIMF508F IC908 Grooving Insert 5mm Cut-grip

Product Description

The ISCAR 6402802 is a solid carbide grooving insert designed for precision grooving and parting operations on CNC lathes and turning centers. Manufactured to the GIMF 508 ISO standard, it carries the IC908 grade with a PVD-applied TiAlN coating and a submicron carbide substrate. The cutting width is 5.00 mm (0.1969 inches) and the maximum depth of cut is 0.12 mm (0.0047 inches). The insert features a positive rake angle of 7 degrees and a corner radius of 0.80 mm (0.0315 inches). It installs as a neutral-hand, single-end insert in the Cut-Grip self-grip toolholding system. Licensed machinists and CNC turning specialists are the primary installers.

This insert is rated for universal primary workpiece material coverage under ISO material codes H, K, M, P, and S, making it suitable for steel, stainless steel, cast iron, non-ferrous alloys, and heat-resistant superalloys. The F chip breaker geometry is suited for finish grooving passes where controlled chip flow and surface finish are critical. It is intended for use in production turning environments where consistent groove width and depth repeatability are required across medium-to-high volume runs.

Key Features

• IC908 grade with PVD TiAlN coating for extended tool life across universal workpiece materials
• Submicron solid carbide substrate for improved edge toughness and wear resistance
• 5.00 mm cutting width with a maximum depth of cut range of 0.00 to 2.00 mm
• Positive rake angle of 7 degrees reduces cutting forces and heat generation
• Self-grip insert holding method provides secure, repeatable seating without additional clamping hardware
• F chip breaker geometry optimized for finish grooving applications
• Conforms to ISO 13399 tooling data standards for compatibility with CAM and presetting systems

Compatibility

Designed for use with ISCAR Cut-Grip series self-grip grooving toolholders that accept GIMF 508 style inserts. Compatible with ISO material groups H, K, M, P, and S as indicated by the manufacturer. Consult the ISCAR Cut-Grip toolholder selection guide to confirm holder compatibility before ordering.

Installation Notes

Installation is performed by a qualified CNC machinist or toolroom technician. Power down or stop the spindle completely and confirm the machine is in a safe state before changing inserts. Seat the insert fully into the self-grip pocket and verify it is locked before resuming cutting. Do not use damaged or chipped inserts, as carbide inserts can fracture under interrupted cuts if the cutting edge is compromised.
