Iscar 6402807 Grooving Insert GDMY808Y IC908 8mm Cut-grip

Product Description

The ISCAR 6402807 is a solid carbide grooving insert designed for precision grooving, parting, and profiling operations on CNC lathes and turning centers. Identified by insert style GDMY and size code 808, it carries the IC908 grade with a PVD-applied TiAlN coating for elevated wear resistance and thermal stability. The neutral hand orientation allows flexible application in standard toolholders. With an 8 mm cutting width and a maximum depth of cut of 27 mm, this insert handles moderate to deep grooving passes in a single setup. It is installed and replaced by machinists and CNC operators during scheduled tooling changes.

This insert is suited for turning operations across a wide range of workpiece materials, classified under primary material codes H, K, M, P, and S, indicating compatibility with hardened steels, cast irons, stainless steels, carbon steels, and heat-resistant superalloys. The Cut-Grip series design uses a clamp-style holding method, making it a double-ended insert that extends usable life per unit. It is appropriate for both roughing and finishing grooving passes in general-purpose and production turning environments.

Key Features

• IC908 submicron solid carbide grade with PVD TiAlN coating for high wear resistance
• 8 mm cutting width with 27 mm maximum depth of cut for deep grooving capability
• Positive rake angle of 7 degrees reduces cutting forces and improves chip flow
• Double-ended insert design extends tooling value per piece
• Chip breaker geometry (Y-style) promotes controlled chip formation
• Clamp-style holding method provides secure seating in Cut-Grip toolholders
• Universal workpiece material classification supports diverse turning applications

Compatibility

Designed for use in ISCAR Cut-Grip series clamping toolholders that accept GDMY 808-style inserts. No additional specific compatible model numbers were provided in the product data.

Installation Notes

Installation and replacement of grooving inserts should be performed by a qualified machinist or CNC technician with the machine fully stopped and the spindle locked out per facility lockout/tagout procedures. Use the appropriate torque wrench and clamp screw specified by the toolholder manufacturer to secure the insert without over-torquing. Inspect the insert pocket and clamp for wear or debris before seating the new insert. Verify tool offset and depth-of-cut parameters in the CNC program before resuming cuts.
