Iscar 6403180 Cutoff Insert Gim 3C IC908 3 Mm Carbide

Product Description

The ISCAR 6403180 is a solid carbide cutoff and grooving insert from the Cut-Grip series, designed for precision parting and grooving operations on CNC lathes and turning centers. It carries the IC908 manufacturer grade, a submicron carbide substrate with a PVD-applied TiN and TiAlN coating for extended wear resistance and thermal stability. The insert features a 3.00 mm cutting width (0.1181 inches) with a neutral lead angle and neutral hand orientation, making it suitable for straight-in grooving and cutoff applications. The self-grip holding method secures the insert positively in compatible Cut-Grip toolholders. Licensed machinists and CNC operators install this insert in production and job-shop turning environments.

This insert is rated for universal primary workpiece material compatibility, covering ISO material groups H, K, M, P, and S. That range covers carbon and alloy steels, stainless steels, cast irons, nonferrous materials, and high-temperature alloys. The GIM 3C insert style with C chipbreaker geometry is suited for grooving and parting on both small- and medium-diameter barstock. It conforms to ISO 13399 standards for cutting tool data representation, simplifying integration into CAM toolpath libraries and tool management systems.

Key Features

• IC908 grade with PVD TiN and TiAlN coating for heat and wear resistance
• 3.00 mm cutting width (0.1181 inches) with neutral lead angle for straight grooving and parting
• Solid submicron carbide substrate for edge strength and dimensional consistency
• Self-grip holding method for secure seating in Cut-Grip series toolholders
• 7-degree relief angle and 0.22 mm corner radius (0.0087 inches) for controlled chip formation
• Conforms to ISO 13399 cutting tool data standards

Compatibility

Designed for use in ISCAR Cut-Grip series toolholders that accept the GIM insert style. Compatible with universal workpiece materials across ISO groups H, K, M, P, and S per supplier data. Verify toolholder pocket size and insert style code before installation.

Installation Notes

Insert installation and replacement should be performed by a qualified machinist or CNC tooling technician with the machine fully stopped and locked out per applicable machine safety procedures. Use the correct torque wrench and clamping screw specified for the Cut-Grip toolholder to seat the insert without cracking the carbide. Inspect the insert pocket and clamping surfaces for chips or debris before seating a new insert. Do not exceed the toolholder manufacturer's recommended depth-of-cut or feed rate for this insert size.
