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 lever for permitting the performance of plunge cuts on workpieces when the table is in chop saw position. An upper guard for the blade is pivotable about the parallelogram lever during plunge cuts in the chop saw position so that its orientation to the table is maintained. 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 a worm gear. The worm gear is adjustable to permit via the parallelogram lever an adjustment of the cut depth of the blade while maintaining the orientation of the upper guard to the table.
