SOLUTION: A drilling jig for a cable wiring box comprises: a support body which can be held in a hand; a front opening cover formed to have a substantially same width dimension as that of the cable wiring box whose rear portion is fixed to the tip of the support body; a rotary shaft which is rotatable inside the support body together with the cover and is fitted so as to be movable in the axis direction; a rotary cutting blade which is fitted, at a portion located inside the cover of the rotary shaft, so as to be covered with the cover; a driving device which can rotationally drive the rotary shaft as well as move it in the axis direction; and a chip suction-removal device for sucking and removing chips generated when cutting a wallboard with the rotary cutting blade fitted to the cover. !
