Ingersoll Cutting Tools 5523115 Turning Insert CNGG431ML

Product Description

The INGERSOLL CUTTING TOOLS 5523115 is a solid carbide turning insert in the CNGG series, designed for precision metal cutting on CNC lathes and turning centers. Identified by grade TT5080 and geometry code CNGG431ML, this insert features an 80-degree diamond shape with a 0.0156-inch corner radius and a 0.508-inch insert length. The AlTiN and Titanium Nitride dual coating is applied via PVD process, delivering high heat resistance and edge stability during demanding cuts. With four usable cutting edges and a neutral hand orientation, this insert provides consistent performance for machinists working in production or job-shop environments.

This insert is engineered primarily for machining stainless steel, superalloys, and titanium - workpiece material codes M and S per ISO classification. The ML chip breaker geometry is suited for light to medium finishing cuts, helping control chip flow and reduce built-up edge on difficult-to-machine materials. It clamps into compatible CNGG-style toolholders and is appropriate for shops running tight-tolerance turning operations where surface finish and edge life are critical. The ISO designation for this insert is CNGG120404ML TT5080.

Key Features

• Solid carbide substrate with AlTiN and Titanium Nitride PVD coating for heat and wear resistance
• 80-degree diamond insert shape (Shape Code C) with 0.0156-inch corner radius
• ML chip breaker geometry optimized for light to medium finishing passes
• Four cutting edges per insert for extended tool life per unit
• Neutral hand insert - compatible with right- or left-hand toolholder setups
• Maximum depth of cut: 0.138 inches; inscribed circle: 0.5 inches

Compatibility

Designed for use in CNGG-series compatible clamping toolholders. Primary workpiece materials are stainless steel, superalloys, and titanium (ISO material codes M and S). ISO designation CNGG120404ML TT5080 may be used to cross-reference compatible tooling systems.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before seating or indexing the insert. Ensure the insert pocket and clamping surfaces are clean and free of chips before securing the clamp screw. Follow the toolholder manufacturer torque specifications for the clamp screw - do not over-torque, as this can fracture the carbide substrate.
