Iscar 6405458 Grooving Insert INR3078 IC808 Solid Carbide

Product Description

The ISCAR 6405458 is a solid carbide grooving insert in the Notch-Grip series, designed for precision external grooving and parting operations on CNC lathes and turning centers. Carrying the IC808 grade with a PVD-applied AlTiN, TiAlN, and TiN multilayer coating, this insert delivers strong wear resistance and thermal stability across a broad range of workpiece materials. It features a 3.96 mm cutting width and a maximum depth of cut of 3.81 mm, making it suitable for moderate-to-deep groove profiles. The double-ended design extends usable tool life per insert. Licensed machinists and CNC turning specialists are the primary installers and users of this tooling.

This insert is intended for use in turning centers and CNC lathes performing grooving, notching, and profiling operations. Its universal primary workpiece material classification covers fine-grained steel, stainless steel, cast iron, heat-resistant superalloys, and non-ferrous materials, corresponding to ISO material groups P, M, K, H, and S. The positive rake angle of 10 degrees reduces cutting forces, which makes it a practical choice for thin-wall parts and interrupted cut scenarios. It seats in Notch-Grip series toolholders designed for the INR insert style and the 3078 insert size code.

• Double-ended insert design for extended tool life per piece
• Positive 10-degree rake angle reduces cutting forces on difficult materials
• Corner radius of 1.98 mm for controlled edge geometry and surface finish
• Conforms to ISO 13399 tooling data standards for CAM and tool management integration

Compatibility

Designed for use with Notch-Grip series toolholders accepting the INR insert style and 3078 insert size code. Compatible with ISO material groups P, M, K, H, and S as designated by the manufacturer.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate torque wrench and insert clamp hardware specified for the Notch-Grip toolholder to avoid cracking the carbide substrate. Inspect the toolholder pocket for chips or debris before seating the insert to ensure proper support and alignment.
