A cut alignment device for a rotary saw having a motor which spins a cutting unit which includes a rotary shaft driven by the motor, a circular blade having a central aperture through which the shaft fits, and a structural housing. The cut alignment device includes the structural housing defining two or more internal compartments, a battery power source carried within the structural housing, and a beam light source, operatively connected to this power source, and also located within the structural housing. The light source projects a light beam from the cutting unit directed slightly away from the plane of the rotary cutting tool or saw blade such that it never intersects the plane of the blade, to assist the operator in cutting accurately.
