Abstract
A rigid tubular housing provides separate enclosures for a drive shaft and a dental tool that are rotatable on axes that are angularly related. A wall separating the two enclosures provides bearing support for tool-driving gears in one of the enclosures and connection to a driving shaft in the other. A latching mechanism envelops the housing and covers it smoothly. The latching mechanism is movable on the longitudinal axis of the tubular housing for controlling access to the enclosure for a dental tool.
