Iscar 6405257 Grooving Insert GPV32341 IC8250 2.80mm

Product Description

The ISCAR 6405257 is a solid carbide grooving insert from the Cut-Grip series, designed for precision grooving operations on ferrous workpieces. Carrying the IC8250 manufacturer grade with an aluminum oxide (Al2O3) PVD coating, this single-end insert delivers a 2.80 mm cutting width and a maximum depth of cut of 2.21 mm. The GPV insert style features a positive rake angle of 7 degrees and a corner radius of 0.32 mm. It is held in place via a clamp-style holding method. Licensed machinists and CNC operators working in production or job-shop environments install this insert in compatible Cut-Grip toolholders.

This insert is suited for grooving and parting applications on stainless steel and steel workpieces, covering ISO material groups M and P. The GPV profile with a neutral hand orientation allows straightforward inline grooving without lateral offset. Typical applications include OD grooving on turned components where tight depth control and surface finish are critical. The insert size code is 32341, and it conforms to ISO 13399 tooling data standards, making it compatible with digital tool management systems.

Key Features

• IC8250 grade solid carbide substrate with Al2O3 PVD coating for wear resistance on steel and stainless steel
• 2.80 mm cutting width with a maximum depth of cut range of 2.00 to 3.00 mm
• Positive rake angle of 7 degrees reduces cutting forces on difficult-to-machine materials
• Corner radius of 0.32 mm for controlled edge geometry and surface finish
• Clamp-style insert holding for rigid, repeatable seating in Cut-Grip toolholders
• Compliant with ISO 13399 for integration with digital tool assembly and CAM systems

Compatibility

Designed for use in ISCAR Cut-Grip series clamping toolholders that accept the GPV insert style with size code 32341. Optimized for grooving stainless steel and steel workpieces in ISO material groups M and P.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or removing the insert. Use the appropriate torque wrench and clamp screw specified by the toolholder manufacturer to secure the insert without overtightening. Inspect the insert pocket and clamp for debris or wear before each insert change to maintain accurate seating and cutting geometry.
