Iscar 6402700 Grooving Insert GPV43561 IC428 Solid Carbide

Product Description

The ISCAR 6402700 is a solid carbide grooving insert in the Cut-Grip series, designed for precision grooving and parting operations on CNC lathes and turning centers. The insert carries the GPV43561 geometry with an IC428 grade coating, applied via CVD process with an Al2O3 and TiC finish for wear resistance and thermal stability. It delivers a 4.03 mm cutting width and a maximum depth of cut of 3.42 mm, making it well suited for moderate-depth grooving passes. The neutral hand orientation allows use in both left- and right-hand toolholders. Machinists and CNC operators working in production or job-shop environments install this insert as part of a dedicated grooving toolblock system.

This insert is intended for grooving, turning, and parting applications on cast iron, steel, and hard materials. The GPV insert style with a positive 5-degree rake angle helps reduce cutting forces on difficult-to-machine workpieces. It is compatible with Cut-Grip series toolholders that accept the GPV43561 insert size. Typical applications include external grooving on shafts, bearing seats, and other turned components in medium to high production runs across automotive, general machining, and toolroom environments.

Key Features

• IC428 grade with CVD-applied Al2O3 and TiC coating for extended tool life on ferrous materials
• 4.03 mm cutting width with a maximum depth of cut of 3.42 mm
• Positive rake angle of 5 degrees to reduce cutting forces
• Neutral hand orientation for flexible toolholder pairing
• Corner radius of 0.45 mm for controlled edge geometry on groove shoulders
• Conforms to ISO 13399 for tool data interoperability

Compatibility

Designed for use with ISCAR Cut-Grip series toolholders that accept the GPV43561 insert size. Suitable for primary workpiece materials including steel (P), cast iron (K), and hard materials (H) per ISO material classification codes.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate torx or clamping key specified for the Cut-Grip toolholder to secure the insert — do not overtighten by hand force alone. Inspect the insert pocket for chips or debris before seating to ensure full and flat insert contact.
