Sandvik Coromant 5756555 Turning Insert WNMG432-MM 2015

Product Description

The SANDVIK COROMANT 5756555 is a WNMG432-MM 2015 grade solid carbide turning insert designed for precision external turning operations. It carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides thermal resistance and wear protection during continuous and interrupted cuts. The insert features an 80-degree trigon shape with a neutral hand orientation, a 1/2-inch inscribed circle, and a 1/32-inch corner radius. It belongs to the T-Max P series and is intended for use by machinists and CNC lathe operators requiring reliable tool life on demanding workpiece materials.

This insert is optimized for turning stainless steel as its primary workpiece material, corresponding to ISO material group M. The MM chip breaker geometry is suited for medium machining conditions where chip control and surface finish are critical. The neutral hand configuration makes it adaptable across a range of tool holders that accept WNMG-style inserts. It is commonly installed in CNC turning centers and manual lathes in job shops, production environments, and precision machining facilities.
