ABSTRACT:
A miter saw including a base, a turntable, a cutting unit rotatably supporting a circular saw blade, and a support unit movably supporting the cutting unit at a position above the turntable. The support unit has a hinge formed with a recess in which a laser oscillator is accommodated. The laser oscillator emits a projected beam line on a surface of a workpiece W. The line indicates the position of a circular saw blade tip and its extension in a diametrical direction of the circular saw blade. The opening of the recess is closed with a cover that has an opening for allowing the laser beam to pass therethrough. The cover is positioned in confrontation with a fence on which the workpiece abuts for positioning. One surface of the cover is finished into a mirror surface which reflects a cutting line marker already marked on the workpiece and reflects a projected beam line.
