A patent-pending, highly textured, multi-layered MT-TiCN layer increases toughness and reduces flank face wear, resulting in lower cost per cutting edge. The inserts’ highly textured Al2O3 layer also minimizes crater wear, and the gold-colored top layer improves wear detection. The gradient carbide substrate boosts wear resistance and toughness. In addition, Walter provides its signature multi-stage post-treatment. This produces an unusually smooth rake face, reducing friction and also increasing toughness.
