ABSTRACT:
A device attachable to a power drill for the collection and removal of material released during drilling procedures. A collecting tube is mounted by a clamp parallel to the longitudinal axis of the power drill, and is movable relative to the power drill. A spout surrounds the drill bit near the tip area. Pressure is applied to the collecting tube or to the spout in closing the drill bit by a spring, so that the collecting tube can have relative motion in the opposite direction, in accordance with the progress of the drilling. The collecting tube is adapted to the contour of the power drill and has a bend in the vicinity of the spout. The collecting tube has, furthermore, a storage space for the material released during the drilling.
