A housing of a circular saw is mounted for displacement in a predetermined direction and has an upper surface. A rotary saw blade is carried by the housing and projects at least in part upwardly of the upper surface thereof. Its general plane is coincident with the predetermined direction. Mounting means is provided for mounting -upwardly proximal to the upper surface of the housing- workpieces which in the aforementioned predetermined direction have at most a predetermined maximum dimension. Supporting plate means is provided on the upper surface of the housing movable with the same and in supporting engagement with a mounted workpiece. According to the invention the supporting plate means comprices a portion which projects beyond the saw blade in the predetermined direction by a distance which at least equals two thirds of the maximum dimension mentioned before to thereby offer additional support to the workpiece.
