Sandvik Coromant 5724408 Turning Insert CNMG432-MR 2025

Product Description

The SANDVIK COROMANT 5724408 is a CNMG-style indexable turning insert in the T-Max P series, manufactured in grade 2025 solid carbide with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN. It features an 80-degree diamond insert shape (shape code C), a neutral hand orientation, and four usable cutting edges. The inscribed circle measures 0.5000 inches (12.70 mm), insert length is 0.4762 inches (12.10 mm), and corner radius is 1/32 inch (0.0313 inches). This insert is designed for turning operations and is typically installed by machinists and CNC lathe operators working in production or job-shop environments.

The CNMG432-MR 2025 insert is optimized for turning stainless steel (ISO material code M). The MR chip breaker geometry is suited for medium turning passes on austenitic and other stainless alloys where controlled chip formation and edge stability are critical. It fits standard CNMG toolholders with clamp and pin holding methods and is a common choice in turning centers and manual lathes handling stainless workpieces in both light and medium cutting conditions.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for wear resistance on stainless steel
• 80-degree diamond insert shape with four usable cutting edges for economical indexing
• MR chip breaker geometry for controlled chip formation in medium turning applications
• Neutral hand orientation for flexible toolholder compatibility
• Clamp and pin holding method for secure seating in standard CNMG toolholders
• ISO code CNMG 12 04 08-MR 2025 for direct cross-reference

Compatibility

Designed for use in standard CNMG-style toolholders that accept clamp and pin holding methods. Primary workpiece material is stainless steel (ISO code M). ISO designation CNMG 12 04 08-MR 2025 may be used for toolholder and catalog cross-reference.

Installation Notes

Indexable turning inserts are installed and indexed by machinists or CNC lathe operators. Power down and lock out the machine spindle before seating or indexing the insert. Verify the insert pocket and seating surfaces are clean and free of chips before clamping. Follow the toolholder manufacturer torque and clamping guidance for CNMG-style inserts and inspect the cutting edge and chip breaker for damage before resuming cuts.
