• Speed regulation:
  Stepless electronic speed regulation of the drive machine for selecting the speed according to the material. The speed is steplessly adjustable on the dial: 200 rpm to 500 rpm (1st gear) or 500 rpm to 1200 rpm (2nd gear). The electronic speed control that is being used keeps the selected speed constant, also under load. Advantage: The optimum drilling speed (load speed) selected for the respective material remains constant for the entire duration of the drilling. For excellent drilling performance and very long life of the drilling crowns.
