Iscar 6405393 Grooving Insert INR3031 IC808 Solid Carbide

Product Description

The ISCAR 6405393 is a solid carbide grooving insert in the Notch-Grip series, designed for external grooving and turning operations on CNC lathes and turning centers. It carries the IC808 manufacturer grade, a fine-grained carbide substrate with a PVD-applied AlTiN, TiAlN, and TiN multilayer coating for heat resistance and edge durability. The insert has a right-hand cutting orientation, a 1.57 mm (0.0620 inch) cutting width, and a maximum depth of cut of 2.39 mm (0.0940 inch). With a positive rake angle of 10 degrees and a lead angle of 3 degrees, it is suited for clean, controlled groove profiles. Licensed machinists and CNC operators install this insert in compatible Notch-Grip toolholders.

This insert is designed for universal workpiece material compatibility, covering ISO material groups H, K, M, P, and S. That range includes steels, stainless steels, cast irons, heat-resistant superalloys, and hardened materials. Typical applications include external grooving, parting-off assistance, and face grooving on precision turned components in general machining, aerospace, and energy sector work. The double-end configuration provides two usable cutting edges per insert, extending tool life per unit. The insert style code is INR with insert size code 3031 and an overall length of 22.86 mm (0.9000 inch).

Key Features

• IC808 grade fine-grained solid carbide substrate for toughness and wear resistance
• PVD coating combining AlTiN, TiAlN, and TiN layers for elevated heat and oxidation resistance
• 1.57 mm cutting width with maximum depth of cut range from 2.00 to 3.00 mm
• Positive rake angle (10 degrees) reduces cutting forces on the workpiece
• Double-end insert design yields two cutting edges per piece
• Compatible with universal ISO material groups H, K, M, P, and S

Compatibility

Designed for use in ISCAR Notch-Grip series toolholders accepting INR-style inserts with insert size code 3031. Compatible across ISO material groups H, K, M, P, and S as stated by the manufacturer. Verify toolholder seat geometry and insert size code before installation.

Installation Notes

Installation is performed by qualified CNC machinists or tool-crib technicians. Power down and lock out the machine spindle before seating or removing inserts. Use the appropriate insert-seating tool or torque wrench as specified by the toolholder manufacturer for the clamping screw. Inspect the toolholder pocket for wear or debris before installing a new insert to ensure proper seating and edge alignment.
