Sandvik Coromant 5734184 DNMG431-MF 2025 Turning Insert

Product Description

The SANDVIK COROMANT 5734184 is a DNMG431-MF 2025 indexable turning insert from the T-Max P series, designed for precision external and internal turning operations on CNC lathes and turning centers. This insert uses a solid carbide substrate with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, delivering wear resistance and thermal stability in demanding cutting environments. It features a 55-degree diamond shape, neutral hand orientation, a 0.5946-inch cutting edge length, and a 1/2-inch inscribed circle. The MF chip breaker geometry is engineered for controlled chip formation. Machinists and CNC operators working in production or job-shop environments install this insert.

This insert is primarily intended for turning stainless steel workpieces, corresponding to ISO material code M. The T-Max P series targets general external turning, profiling, and facing applications where consistent tool life and surface finish are required. With four cutting edges per insert, the 5734184 delivers efficient cost-per-edge performance in medium to light finishing cuts on stainless steel components typical in industrial, food processing, medical, and oil and gas part production.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for wear resistance on stainless steel
• MF chip breaker geometry for controlled chip evacuation in finishing and light medium cuts
• 55-degree diamond insert shape (DNMG) with neutral hand for versatile tool holder compatibility
• Four usable cutting edges per insert for reduced cost per edge
• Clamp and pin insert holding method for secure seating in T-Max P tool holders
• ISO grade 2025 carbide substrate balanced for toughness and deformation resistance

Compatibility

Designed for use in tool holders accepting DNMG-style inserts with a clamp and pin holding method, consistent with T-Max P series tooling. ISO code designation is DNMG 15 04 04-MF 2025. Verify tool holder bore and clamp style before installation.

Installation Notes

Insert replacement is performed by qualified machinists or CNC tooling technicians following lockout/tagout procedures before accessing the turret or tool holder. Use the appropriate torx or hex key to the tool holder manufacturer torque specification when seating the clamp screw. Inspect the insert pocket and locating pin for debris or damage before seating a new insert. Never use a worn or chipped insert edge, as it can cause workpiece damage or unpredictable tool failure.
