Multi-Drills Number of holes Coating Hardness (GPa) Drill Coating DEX Coating General Features l Sumitomo Electric Hardmetal‘s next-generation drill coating utilises nano-coating technology to provide more than double the tool life of conventional coatings. l Silicon and chrome improve usure, heat, and adhesion resistance. l New super multi-layered structure offers significantly improved chip resistance (coating strength). Characteristics l Characteristics of Films l Coating Design DEX (TiAlCr/TiSi) World‘s first combined 50 super multi-layered TiAlCr coating is made from Supermulti-Layer 40 TiSiN alternate layers of super coating multilayered substrates.
