A waterspout structure for a hammer drill is provided to make an inner wall of a main body smooth by equipping a reinforcement ring at the outer side of the main body to conveniently clean the main body after the operation. A waterspout structure for a hammer drill includes a hammer drill, and a waterspout(200). The hammer drill punches an anchor bolt groove at a ceiling. The waterspout gathers scattering substances at one position. The waterspout includes a cup-shaped main body(230), a bearing, a filter, and a reinforcement ring(240). The cup-shaped main body is adhered to the ceiling at its upper part and inserted into a lower end of the drill at its lower part. The bearing prevents rotation of the main body when the drill is rotated. The filter is coupled with the upper end of the bearing to prevent the scattered substances from being intruded into the bearing. The reinforcement ring folds the upper end of the main body and returns the upper end.
