Sandvik Coromant 5756292 Turning Insert WNMA432KR 3210

Product Description

The SANDVIK COROMANT 5756292 is a solid carbide turning insert from the T-Max P series, designed for single-point turning operations on cast iron workpieces. It carries a three-layer CVD coating of TiCN, Al2O3, and TiN, which delivers high wear resistance with moderate toughness across roughing and medium machining applications. The insert follows ANSI code WNMA432 and ISO code WNMA080402, features an 80-degree trigon shape, a neutral hand orientation, and a negative side clearance with a tolerance code of M. With six available cutting edges and compatibility with both clamp and pin holding methods, this insert offers extended tool life per edge on demanding cast iron cuts.

This insert is suited for lathe and turning center operations targeting cast iron materials in both roughing and medium machining passes. The KR chip breaker geometry is optimized for cast iron grade K applications, making it a direct fit for production environments where consistent chip control and wear resistance are priorities. The T-Max P series is a well-established platform used in horizontal and vertical turning setups across job shop and production machining environments. Licensed machinists and CNC turning specialists are the primary installers and users of this insert.
