Duratomic® is an exclusive insert coating technology that brings an exceptional combination of wear resistance and edge toughness to a wide variety of Seco grades. Nanoscience at its best, the Duratomic® CVD aluminum-oxide coating process manipulates coating components at an atomic level to improve the mechanical properties as well as the thermal and chemical inertness of many of the company's products. By controlling the atomic structure of its coatings, Seco can ensure the best part of the structure is engaged in the cut. Such control also yields a smoother surface, resulting in less friction and heat during the cut for unmatched tool life and speed capabilities.
