Sandvik Coromant 5724239 CNMG432-MF 1115 Turning Insert

Product Description

The SANDVIK COROMANT 5724239 is a CNMG432-MF turning insert from the T-Max P series, designed for precision external turning operations in metalworking environments. Built from solid carbide with a TiAlN and AlCr2O3 dual-layer PVD coating, this insert delivers thermal resistance and edge stability at elevated cutting speeds. The 80-degree diamond insert shape (shape code C) provides a strong cutting geometry suited to continuous and semi-interrupted cuts. With a 0.5000-inch inscribed circle, a 0.4762-inch insert length, and a 1/32-inch corner radius, the insert fits standard CNMG toolholders and is handled by machinists and CNC turning specialists working in production and job shop environments.

This insert is optimized for primary use on stainless steel (ISO material code M) and rated for secondary applications on superalloys and titanium (ISO material code S). The MF chip breaker geometry is engineered for medium to finishing cuts where chip control and surface finish are priorities. It is well suited to CNC turning centers, gang-tool lathes, and manual turret lathes running stainless and heat-resistant alloy components. The ISO designation for this insert is CNMG 12 04 08-MF 1115. Sold individually; minimum order quantity is 10 pieces.

Key Features

• TiAlN and AlCr2O3 PVD dual-layer coating for heat resistance and extended tool life in stainless and superalloy cuts
• MF chip breaker geometry optimized for medium finishing passes with reliable chip evacuation
• 80-degree diamond insert shape with neutral hand orientation for flexible toolholder compatibility
• 4 usable cutting edges per insert for cost-effective tool management
• Clamp and pin insert holding method for secure, repeatable seating in the toolholder
• Zero-degree relief angle (clearance code N) with tolerance code M for precise dimensional fit

Compatibility

Designed for use in standard CNMG-style toolholders accepting a 0.5000-inch inscribed circle insert with clamp and pin retention. ISO designation CNMG 12 04 08-MF 1115 confirms fitment in toolholders specifying that insert code. Part of the SANDVIK COROMANT T-Max P series.

Installation Notes

Insert replacement and indexing should be performed by a qualified machinist or CNC tooling technician with the spindle locked and machine power isolated per shop safety procedures. Ensure the insert pocket and seating surfaces are clean and free of chips before seating the new insert. Clamp and pin retention must be verified to the toolholder manufacturer's specified procedure before resuming cutting. Refer to SANDVIK COROMANT T-Max P toolholder documentation for correct torque and clamping sequence.
