Abstract
An air-driven rotating and cutting device or handpiece has a double-wheel rotor. The handpiece includes connecting channels for guiding air from first turbine blades to second turbine blades. Each of the channels is defined by an opening opened toward a direction parallel to the rotational axis and a surface portion formed by extending the opening to a direction along the rotational axis.
