Kavo 642B Bella Torque – Push Button Auto Chuck

Kavo produces the best auto chuck available, which easily withstands the rigors of daily use and heat sterilization. Keep them clean and lubricated (without over lubricating), and Kavo turbines have unmatched longevity. Speed averages around 410,000 RPM @33 psi which provides good power without the noise encountered with many competitors. The Kavo 642B incorporates the auto regulator valve to ensure pressure to turbine is maintained consistent regardless of unit pressure. This adds convenience when other handpieces being powered from the same unit require higher pressures to operate. Many times, slow speeds take a little more pressure to operate at maximum efficiency. While Kavo recommends factory servicing, the turbines can be replaced by the user without too much trouble. Just remember to clean interior of handpiece, and replace the provided o-rings to ensure turbine remains sealed and well seated within the handpiece head. You’ll also need keep track of the back cap wrench included with new handpiece purchase, or obtain one from your dealer if handpiece is purchased used.
