Iscar 6404321 Grooving Insert IC8250 10mm Cut-grip

Product Description

The ISCAR 6404321 is a solid carbide grooving insert carrying the GIF1000080E geometry and IC8250 manufacturer grade. It is designed for external grooving operations on CNC turning centers and is held in place via a clamp-style toolholder. The insert features a 10 mm cutting width, a 6 mm maximum depth of cut, and a 0.80 mm corner radius, making it well suited to producing precise grooves in demanding workpiece materials. The Al2O3 finish is applied via PVD coating for extended tool life in interrupted and continuous grooving cuts. Machining professionals working in production turning environments will find this insert appropriate for high-cycle grooving work.

This insert is intended for use on stainless steel and steel workpieces, covering ISO material groups M and P. Its neutral hand orientation and double-end configuration make it adaptable across a range of setups within the Cut-Grip series system. The GIF insert style with a positive 7-degree rake angle supports chip control when grooving austenitic stainless steels and carbon or alloy steels. It is a standard replacement-grade insert for production shops running ISCAR Cut-Grip toolholders in medium to high-volume turning applications.

Key Features

• 10 mm cutting width with a maximum depth of cut of 6 mm for precise groove profiling
• Solid carbide substrate with IC8250 grade and PVD-applied Al2O3 coating for wear resistance
• Double-end insert design extends usable life per insert
• Positive 7-degree rake angle promotes efficient chip formation and reduced cutting forces
• 0.80 mm corner radius minimizes stress concentration at groove shoulders
• Conforms to ISO 13399 tooling data standards for compatibility with CAM and tooling management systems

Compatibility

Designed for use with ISCAR Cut-Grip series clamp-style toolholders accepting the GIF insert style. Primary workpiece materials are stainless steel (ISO group M) and steel (ISO group P).

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the turret is in a safe index position before seating or replacing inserts. Use the appropriate ISCAR clamp key to secure the insert to the specified clamping torque indicated in the toolholder documentation. Inspect the insert seat and clamp for wear or debris before mounting a new insert to ensure proper seating and runout.
