Ingersoll Cutting Tools 5515664 CNMG432MP Turning Insert

Product Description

The INGERSOLL CUTTING TOOLS 5515664 is a solid carbide turning insert in the CNMG432MP TT8020 configuration, designed for single-point turning operations on CNC lathes and turning centers. Coated with titanium carbonitride (TiCN) via a PVD process, it carries the manufacturer grade TT8020 and delivers consistent performance on demanding workpiece materials. The insert features an 80-degree diamond shape with a neutral hand orientation, a 0.5-inch inscribed circle, and a 0.031-inch corner radius. With four cutting edges and an MP chip breaker geometry, it is built for productive metal removal rates while maintaining edge integrity. Machinists and CNC operators in production and job-shop environments install this insert as part of a clamp-style toolholder system.

This insert is suited for turning stainless steel, carbon and alloy steel, and super-alloys including titanium. Its TiCN coating and negative rake geometry make it a strong fit for medium to semi-finish turning passes where chip control and edge stability are priorities. The MP chip breaker geometry handles a wide range of feed rates and depths of cut up to 0.157 inches, making it versatile across roughing and finishing transitions in production turning. It follows the ANSI code CNMG432MPTT8020 and ISO code CNMG120408MP TT8020, conforming to ISO standards.

Key Features

• Solid carbide substrate with PVD TiCN coating for wear resistance on ferrous and high-temp alloys
• 80-degree diamond insert shape (CNMG) with negative rake for strong cutting edge geometry
• MP chip breaker designed for stainless steel, steel, super-alloys, and titanium
• Four usable cutting edges for extended tool economy per insert
• Clamp-style insert holding compatible with standard CNMG-seat toolholders
• Maximum depth of cut of 0.157 inches with a 0.031-inch corner radius for finish to medium turning

Compatibility

Designed as a direct-fit replacement for CNMG432 series clamp-style toolholders conforming to ANSI and ISO CNMG insert seat standards. Compatible with material grades C1 through C6 application ranges per the ANSI code CNMG432MPTT8020 and ISO code CNMG120408MP TT8020.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or indexing the insert. Use the correct torque wrench for the clamp screw as specified by the toolholder manufacturer - do not overtighten, as this can fracture the carbide. Inspect the insert pocket for chips or debris before seating each new edge.
