Abstract

A circular saw assembly comprises a frame and a table mounted in the frame that is movable between a chop saw and a table saw position in which the depth of the cut may be adjusted. The assembly has a parallelogram never rotatable about a pivot member for permitting the performance of plunge cuts on workpieces when the table is in chop saw position. A rack extends from the end of the parallelogram lever opposite the upper guard so that, when the assembly is converted to table saw position, the rack engages an adjustable worm gear for adjusting cut depth. A spring biasses the saw assembly away from the table when in chop saw position. In table saw position, the spring is releasable by an intermediate toggle lever so that the worn gear may be adjusted without the user having to work against the spring pressure when setting cut depth.
