Sandvik Coromant 5725525 Turning Insert Cnmg T-max P

Product Description

The SANDVIK COROMANT 5725525 is a CNMG-style indexable turning insert engineered for precision metal cutting in demanding production environments. It carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN over a solid carbide substrate, delivering wear resistance and thermal stability across a broad range of cutting conditions. The insert features an 80-degree diamond shape, a neutral hand orientation, and a corner radius of 0.0469 inches. With four usable cutting edges per insert, it offers strong tool life economics for high-volume turning operations. Licensed machinists and CNC lathe operators in job shops and production facilities are the primary installers and users of this tooling.

This insert is designed primarily for turning stainless steel workpieces, aligning with ISO material group M. It belongs to the T-Max P series, which is engineered for external and internal turning on CNC lathes and turning centers. The MR chip breaker geometry is suited for medium-range cutting depths and feed rates on austenitic and other stainless steel alloys. It is identified by ISO code CNMG 19 06 12-MR 2025 and carries SANDVIK COROMANT grade 2025.

Key Features

Compatibility

Designed for use in toolholders accepting CNMG 643 inserts with clamp and pin holding methods, compatible with T-Max P series turning systems. Primary workpiece material is stainless steel (ISO material group M).

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or indexing the insert. Ensure the toolholder pocket and clamping components are clean and free of chips before placing the insert to maintain proper edge location. Do not exceed the toolholder or machine manufacturer's recommended cutting parameters for this insert geometry and grade.
