Iscar 6402274 Grooving Insert IC354 Solid Carbide Ticn

Product Description

The ISCAR 6402274 is a solid carbide grooving insert from the Cut-Grip series, designed for precision grooving operations on CNC lathes and turning centers. It carries the GIM3J8A designation with ISCAR grade IC354, a PVD-applied TiCN coating that improves wear resistance and surface finish on difficult-to-machine workpiece materials. The insert features a neutral hand orientation and a 0.1181 inch (3.00 mm) cutting width, making it well-suited for consistent groove dimensions in production environments. A licensed machinist or CNC setup technician installs and indexes this insert as part of a Cut-Grip toolholder system.

This insert is intended for grooving stainless steel and steel workpieces, corresponding to ISO material classifications M and P. The IC354 grade with TiCN PVD coating is particularly effective in applications requiring extended tool life on austenitic stainless steels and carbon or alloy steels. It is a single-ended insert with a positive rake geometry (7-degree rake angle, 8-degree lead angle) and a chip breaker style A, suited for controlled chip formation in finish and semi-finish grooving cuts. Typical use is in medium-to-high production turning operations where repeatable groove width and wall finish are critical.

Key Features

• Solid carbide construction with PVD TiCN coating for wear resistance on stainless steel and steel
• 0.1181 inch (3.00 mm) cutting width for precise groove sizing
• Positive rake geometry with 7-degree rake angle and chip breaker style A for controlled chip evacuation
• IC354 manufacturer grade rated for ISO material groups M (stainless steel) and P (steel)
• 0.0087 inch (0.22 mm) corner radius for defined groove edge geometry
• Neutral hand orientation compatible with Cut-Grip series toolholders
• Compliant with ISO 13399 insert identification standards

Compatibility

Designed for use with ISCAR Cut-Grip series toolholders and grooving systems that accept the GIM 3J insert style. Compatible with applications targeting stainless steel (ISO code M) and steel (ISO code P) workpiece materials. Verify toolholder seat and clamping compatibility with ISCAR Cut-Grip documentation before installation.

Installation Notes

Installation is performed by a qualified machinist or CNC toolroom technician. Power down and lock out the machine spindle before indexing or replacing any insert. Use the appropriate ISCAR torx or clamping key for the Cut-Grip seat to avoid over-torquing the clamping screw. Inspect the insert pocket and seating surface for chips or debris before seating the new insert to ensure proper support and cutting-edge registration.
