  • W&H - Dental Handpieces - What should you look for

    With turbines the bur is directly driven by a rotor. The rotor has an impeller powered by compressed air. Turbines reach an idle speed of up to 400,000 min-1. The working speed depends on the pressure exerted and is approximately half the idle speed - i.e. approx. 150,000 to 250,000 min-1. The maximum power of 10-26 W is also reached in this speed range.
