A portable radial saw consisting of a planar work table, an arm extending horizontally over the table, being pivoted on a vertical axis to the table adjacent one edge of the table and guided for movement concentric to its pivotal axis adjacent the opposite edge of the table, being connected to the table by vertically yieldable connectors whereby to rest by gravity on work pieces supported on the table, a carriage movable along the arm and adapted to carry a power saw operable to saw a work piece on the table as the carriage traverses the table, clamps operable to secure both ends of the arm solidly against pivotal movement, and a gauge operable to preset the depth of the saw cut despite the variable elevation of the arm above the table.
