Sandvik Coromant 5724071 CNMG431-WF 3005 Turning Insert

Product Description

The SANDVIK COROMANT 5724071 is a CNMG-style indexable turning insert in the T-Max P series, designed for external and internal turning operations on CNC lathes and turning centers. The insert is manufactured from solid carbide and carries a multi-layer MTCVD coating of TiCN, Al2O3, and TiN for extended wear resistance and thermal stability. With an 80-degree diamond shape, a 0.5-inch inscribed circle, and a 1/64-inch corner radius, this neutral-hand insert is suited for general-purpose steel turning where consistent tool life and surface finish are priorities. Licensed machinists and CNC operators install this insert as a direct drop-in replacement in compatible toolholders.

This insert is primarily rated for steel (ISO material code P) and secondarily for cast iron (ISO material code K). It fits standard CNMG toolholders that accept clamp and pin holding methods, making it applicable across a broad range of turning center setups in production and job-shop environments. The WF chip breaker geometry is optimized for finishing and light-to-medium roughing passes, making it versatile across common turning scenarios on steel workpieces. ISO code for this insert is CNMG 12 04 04-WF 3005.

Installation Notes

Installation is performed by qualified machinists or CNC toolroom technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and clamp hardware specified for the toolholder to avoid insert rocking or premature breakage. Inspect the insert seat and clamp for wear or debris before seating a new insert.
