The “adaptive torque control” (ATC) system delivers the most powerful air-driven handpiece available. Exceptional part-air, part-electric ATC intelligence ensures constant power for quick removal of old restorations and tooth structure. Speed-sensing intelligence (SSI) monitors bur speed according to load and adjusts speed automatically to minimize wear on bearings. Delivers smooth, constant power and control for unmatched cutting efficiency and faster removal of material. Its “superior turbine suspension” (STS) feature allows the handpiece to operate at speeds of 330,000 rpm under load without noticeable bur deflection and chattering for better control and precision. Mid- and mini-sized head options allow for enhanced maneuverability in oral cavity. Accepts standard and short-shank burs. Lightweight, ergonomic design and whisper-quiet operation ensures comfortable working environment and reduces patient anxiety. Adapts to user’s technique with unprecedented efficiency for clinical excellence. 3-year warranty on control source, power supply, and integrated coupler and tubing; 2-year warranty on handpiece.
