Ingersoll Cutting Tools 5523121 Turning Insert CNGG430.5ML

Product Description

The INGERSOLL CUTTING TOOLS 5523121 is a solid carbide turning insert in the CNGG series, designed for precision metal removal on CNC lathes and turning centers. It carries the manufacturer grade TT5080 with a PVD-applied AlTiN and TiN dual coating for heat and wear resistance at elevated cutting speeds. The insert features an 80-degree diamond shape, a neutral hand orientation, and an ML chip breaker geometry. With a 0.5-inch inscribed circle and a 0.0079-inch corner radius, it delivers controlled chip formation and consistent surface finish in demanding turning applications. Licensed machinists and CNC operators are the primary installers of this insert.

This insert is engineered primarily for turning stainless steel, super-alloys, and titanium - workpiece material codes M and S - where thermal stability and edge toughness are critical. The CNGG geometry with a negative rake angle and zero-degree relief angle suits clamp-style toolholders in high-accuracy turning setups. Typical applications include finish and semi-finish turning passes where tight tolerances and surface integrity are required. The ML chip breaker is well-suited for light-to-medium depth-of-cut operations on difficult-to-machine alloys.

Key Features

• Solid carbide substrate with PVD AlTiN and TiN coating for extended tool life in high-temperature cuts
• 80-degree diamond insert shape (CNGG) with 4 cutting edges for maximum indexing value
• ML chip breaker geometry optimized for light-to-medium finishing cuts on stainless steel and super-alloys
• 0.0079-inch corner radius for controlled surface finish on precision turned components
• Maximum depth of cut of 0.047 inches suited for finish and semi-finish turning passes
• Clamp-style holding method compatible with standard CNGG toolholder systems
• ISO-compliant designation CNGG120402ML TT5080 for cross-reference with ISO toolholder systems

Compatibility

Designed for use in clamp-style CNGG toolholders accepting a 1/2-inch inscribed circle, 3/16-inch thick diamond turning inserts per ISO standards. Confirmed compatible workpiece materials include stainless steel, super-alloys, and titanium (ISO material codes M and S).

Installation Notes

Installation is performed by CNC machinists or toolroom technicians. Always power down and lock out the machine before indexing or replacing inserts. Seat the insert fully and evenly in the toolholder pocket before tightening the clamp to avoid insert rocking or chipping. Follow the toolholder manufacturer's clamping torque specifications and verify insert seating visually before resuming cutting operations.
