Ingersoll Cutting Tools 6212517 Turning Insert CNMG432RT

Product Description

The INGERSOLL CUTTING TOOLS 6212517 is a solid carbide turning insert designed for steel turning operations in CNC lathe and turning center applications. Manufactured to ANSI code CNMG432 and ISO code CNMG120408, this insert carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, engineered to deliver high wear resistance while maintaining toughness across roughing and medium machining passes. The 80-degree diamond (rhombic) shape provides a strong cutting geometry, and the RT chip breaker is optimized for consistent chip control during steel removal. Four usable cutting edges maximize tooling value per insert.

This insert is suited for roughing and medium machining of steel workpieces in production turning environments. It is used by CNC machinists and toolroom operators running external and internal turning operations where predictable tool life and wear resistance in the P-grade steel category are required. The neutral hand orientation allows installation in standard CNMG-style toolholders without directional restriction, making it a practical choice for general turning setups.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for high wear resistance on steel
• 80-degree diamond insert shape with negative rake and 0-degree relief angle for robust cutting edge strength
• RT chip breaker designed for roughing and medium machining chip control
• Four cutting edges per insert for extended tooling service
• 0.031 inches corner radius for surface finish and edge stability balance
• Maximum depth of cut of 0.236 inches supports aggressive material removal passes

Compatibility

Designed as an OEM-style replacement or direct application insert for CNMG-style toolholders accepting ANSI size code 432 inserts with a 1/2 inch inscribed circle and clamp-style holding.

Installation Notes

Installation is performed by CNC machinists or toolroom technicians using standard CNMG insert clamp toolholders. Ensure the machine spindle is fully stopped and the toolholder is clear of the work zone before indexing or replacing inserts. Use the correct torque wrench per the toolholder manufacturer's specifications when securing the clamp screw. Inspect the insert pocket for chips or debris before seating the insert to ensure proper contact and edge alignment.
