There is a high quality High Speed Dental Lab Handpiece that operates at speeds about 100,000 to 800,000 rpm. It operates with a water spray and may have a fiber-optic light to facilitate better visibility. A water spray is necessary to reduce the temperature within the handpiece and surgical site. This incredible speed is important for precision treatment like polishing and cleaning the teeth, shaping fillings, crowns, and other restoration work. The High Speed Dental Lab Handpiece is very easy to use.
