A tool support stand includes carrying means for a drill or similar tool connected to the upper end of an inner support sleeve which is slidably and axially movable within an outer support sleeve. The outer support sleeve is in turn slidably and axially movable within a mounting block carried by at least three legs. An hydraulic cylinder and ram mounted coaxially within the support sleeves can move the inner sleeve within the outer sleeve and an auxiliary drive mechanism is operable to effectively extend the stroke of the ram by moving the outer sleeve upwardly within the mounting block. The carrying means may include devices to assist the orientation of the tool relative to a workpiece.
