Iscar 6405214 Grooving Insert GIPI4P IC8250 Solid Carbide

Product Description

The ISCAR 6405214 is a solid carbide double-ended grooving insert in the Cut-Grip series, designed for precision grooving and parting operations on CNC lathes and turning centers. It carries the GIPI4P insert style with an IC8250 grade substrate and an Al2O3 CVD coating, delivering wear resistance and thermal stability at high cutting speeds. The insert features a 0.1575 inch cutting width, a maximum depth of cut of 0.61 inches, and a positive rake geometry that reduces cutting forces on difficult-to-machine materials. Machinists and CNC turning specialists are the primary installers of this insert type.

This insert is suited for grooving, parting, and face grooving operations in both production and job-shop environments. Its primary workpiece materials are stainless steel and steel, making it a practical choice for aerospace, medical, and general metalworking applications where tight tolerances and surface finish are required. The neutral hand orientation allows it to fit standard Cut-Grip toolholders without directional restriction. The double-ended design extends usable insert life by providing two cutting edges per insert.

Key Features

• IC8250 grade with Al2O3 CVD coating for thermal resistance and extended tool life in steel and stainless steel
• 0.1575 inch cutting width with a maximum depth of cut of 0.61 inches
• Positive rake angle reduces cutting forces and heat generation
• Double-ended insert geometry provides two cutting edges per piece
• GIPI4P insert style with neutral hand for broad toolholder compatibility
• Chip breaker style P suited for medium cutting conditions in steel-family materials

Compatibility

Designed for use in ISCAR Cut-Grip series toolholders accepting GIPI-style inserts with insert seat size 4. Compatible with standard ISO 13399 compliant tooling systems. Primary workpiece materials are stainless steel (ISO material code M) and steel (ISO material code P).

Installation Notes

Insert replacement is performed by qualified machinists or CNC tooling technicians. Always power down and lock out the machine before changing inserts. Seat the insert fully and evenly in the toolholder pocket before torquing the clamping screw to the toolholder manufacturer specification. Inspect the insert seat for chips or debris before installing a new edge to ensure proper seating and prevent premature edge failure.
