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).
