The Prime Line spindle has a two-part bur guide with a carbide shell for the highest level of concentricity and resistance to bending. With over 40 N of retention force, the spindle guarantees that the bur is securely held. The automatic return suction stop effectively prevents particles and saliva from entering into the head's housing. The glass rod light conductor enables true-color, antiglare, and uniform lighting of the entire mouth with more than 25,000 lux. The vibration-free running results in a sound level of less than 55 dB. This makes the Prime Line the quietest turbines in the world.
The Eco Line spindle has a drill guide with steel sleeve for maximum concentricity and a holding force of 30 N. The perfect balance of each rotor guarantees a vibration-free running and maximum wear resistance. The glass rod light conductor enables true-color, antiglare, and uniform lighting of the entire mouth with more than 25,000 lux.
