Iscar 6401925 Grooving Insert GIMY808Y IC20 8mm Cut-grip

Product Description

The ISCAR 6401925 is a solid carbide grooving insert in the Cut-Grip series, designed for precision grooving and parting operations on CNC lathes and turning centers. Carrying the GIMY808Y insert style designation and IC20 uncoated carbide grade, this neutral-hand insert delivers an 8 mm cutting width with a maximum depth of cut of 4.80 mm. The positive 7-degree rake angle promotes clean chip formation and reduces cutting forces across a broad range of workpiece materials. At 15.30 mm overall length, this single-end insert is held in place by a clamp-style toolholding system and is well suited to high-precision grooving applications where dimensional consistency is critical.

This insert is rated for universal primary workpiece material compatibility, covering ISO material groups H, K, M, N, and S. That range spans hardened steels, cast irons, stainless steels, non-ferrous metals, and heat-resistant superalloys, making it a versatile option for job shops and production turning environments. The Cut-Grip series is widely used in both light and medium-duty grooving, face grooving, and parting operations on small-to-medium diameter workpieces. The Y chip breaker geometry supports effective chip control at typical grooving feed rates.

Key Features

• 8 mm cutting width with a 0.80 mm corner radius for consistent groove geometry
• Maximum depth of cut of 4.80 mm, within a rated range of 4.00 to 5.00 mm
• IC20 uncoated solid carbide grade engineered for sharp-edge cutting and fine surface finishes
• Positive 7-degree rake angle reduces cutting forces and promotes chip evacuation
• Neutral hand orientation allows use in standard right-hand Cut-Grip toolholders
• Clamp-style insert retention provides secure seating and repeatable edge indexing
• Compliant with ISO 13399 cutting tool data representation standards

Compatibility

Designed as a direct-fit replacement insert for ISCAR Cut-Grip series toolholders and cartridges accepting GIMY 808-style inserts. Compatible across ISO material groups H, K, M, N, and S as specified by the manufacturer.

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 indexing the insert. Use the appropriate ISCAR clamping key to secure the insert fully before resuming cutting operations. Do not exceed the manufacturer-specified maximum depth of cut for the toolholder and insert combination in use.
