ABSTRACT:
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 blade mounting device for holding the blade on the shaft. The cut alignment device includes a battery power source carried by the cutting unit; and a beam light source, operatively connected to this power source, and carried by the cutting unit. The light source projects a light beam at a shallow angle from the cutting unit directed to intersect the plane of the rotary cutting tool or saw blade, to assist the operator in cutting accurately.
