Iscar 6405252 Grooving Insert GIP478E055P IC8250

Product Description

The ISCAR 6405252 is a double-ended solid carbide grooving insert carrying grade IC8250 with an Al2O3 CVD coating. It belongs to the Cut-Grip series and is designed for external and face grooving operations on CNC lathes and turning centers. The insert delivers a 4.78 mm (0.1882 inches) cutting width and a maximum depth of cut of 13.00 mm (0.5118 inches). A positive rake angle of 7 degrees and a P chip breaker geometry work together to control chip evacuation during continuous and interrupted cuts. The clamp-style insert holding method provides repeatable seating and quick indexing on compatible toolholders.

This insert is suited for grooving, parting, and profile turning in both production and job-shop environments. Primary workpiece materials are stainless steel and carbon or alloy steel, corresponding to ISO material groups M and P. The double-end design extends usable life per insert, reducing per-cut tooling cost on high-volume turning operations. Typical applications include groove profiling, undercuts, and snap-ring grooves on turned components where tight width tolerances are required. A licensed machinist or CNC operator installs and indexes this insert.

Key Features

• IC8250 grade with CVD-applied Al2O3 coating for wear resistance on steel and stainless steel
• 4.78 mm cutting width with a 0.55 mm corner radius for controlled groove geometry
• Positive 7-degree rake angle and P chip breaker for reliable chip control
• Double-end insert design provides two usable cutting edges per insert
• Maximum depth of cut range of 10.00 mm to 20.00 mm supports a range of groove depths
• Conforms to ISO 13399 tooling data standards for compatibility with CAM and tool management systems

Compatibility

Designed for use in ISCAR Cut-Grip series clamping toolholders that accept the GIP insert style in size code 478E055. Confirm toolholder acceptance of a 4.78 mm insert width before installation.

Installation Notes

Index and seat this insert in the toolholder pocket using the appropriate torx or hex key as specified by the toolholder manufacturer; do not overtighten the clamp screw. Power down and lock out the machine spindle before changing or indexing any insert. Inspect the toolholder pocket for chips or wear before seating a new cutting edge. Dispose of worn carbide inserts in accordance with applicable shop and local regulations for carbide tooling waste.
