Abstract
A rotary table saw for sectioning dental models having a housing with a base portion and a working table mounted on the base portion. The working table is controllably depressible so as to be moved upward and downward with respect to the base. The motor housed in the base drives a rotary blade oriented in a vertical direction. A slit in the work table permits the blade to emerge therethrough as the work table is depressed. The vacuum outlet is placed in flow communication with the surface of the work table during depression of the work table to remove saw dust from the work table. The dental model is placed on the work table with the blade hidden beneath the work table. The work table is depressed to permit emerging of the rotary blade cutting from the underside of the dental model.
