A saw extension for supporting a hand-held portable rotary saw has a base, a plurality of wheels positioned to support the base above a surface, and an upwardly extending arm extending from the base to a control grip. The hand-held portable rotary saw is removably attached to the base with at least one locking pin positioned through a guide plate of the hand-held portable rotary saw and into at least one locking aperture of the base. The saw extension includes a power control mechanism mounted adjacent the control grip. The power control mechanism includes a power socket into which a saw power cord of the hand-held portable rotary saw can be plugged, a master power cord for electronically connecting the power socket with an external power source, and a trigger switch for operably controlling the flow of power to the hand-held portable rotary saw.
