Advanced technology and innovative design have enabled Hu-Friedy to produce a superior composite instrument: Satin Steel™ XTS™. XTS composite instruments allow for exceptional non-stick placement of materials without discoloring the restoration. Studies indicate Aluminum Titanium Nitride (AlTiN) coatings are consistently harder, smoother and stick less as compared to Titanium coatings. Additionally, Hu-Friedy XTS instruments are made from Immunity Steel™ for longer life.
