Ingersoll Cutting Tools 5520967 Turning Insert CNMG432EM TT9215

Product Description

The INGERSOLL CUTTING TOOLS 5520967 is a solid carbide turning insert designed for precision metal removal on CNC and manual lathes. Carrying the CNMG432EM geometry and TT9215 manufacturer grade, it features a multilayer CVD coating of TiCN, Al2O3, and Titanium Nitride applied for wear resistance and thermal stability. The 80-degree diamond insert shape and neutral hand orientation make it a reliable choice for external and internal turning operations. With four usable cutting edges and an EM chip breaker configuration, the insert supports productive, controlled cutting cycles on demanding materials.

This insert is engineered for use on stainless steel, super-alloys, and titanium workpieces, covering primary material codes M and S. It is suited for both roughing and semi-finishing passes where chip control and edge life are critical. Typical applications include aerospace, medical, and energy-sector component turning where workpiece material toughness demands a robust, well-coated carbide grade. The insert mounts via clamp-style holders and fits standard CNMG tooling systems used across production and job-shop environments.

Key Features

• Solid carbide substrate with multilayer CVD coating: TiCN, Al2O3, and Titanium Nitride for extended tool life
• 80-degree diamond insert shape (Shape Code C) with negative rake for strong cutting edge
• EM chip breaker geometry optimized for stainless steel and super-alloy turning
• Four cutting edges per insert for cost-effective use
• 0.031-inch corner radius balances edge strength and surface finish
• Neutral hand orientation fits a wide range of CNMG clamp-style holders

Compatibility

Designed for use in standard CNMG clamp-style toolholders accepting the 432 insert size. ANSI Code: CNMG432EMTT9215. ISO Code: CNMG120408EM TT9215.

Installation Notes

Turning insert replacement is performed by machinists and CNC tool-setup personnel. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torx or hex key to release the clamp screw, seat the new insert fully against the pocket locating surfaces, and retorque the clamp screw per the toolholder manufacturer specification. Inspect the insert pocket for chips or wear before seating each new edge.
