The following nozzle allows you to reduce the amount of dust that appears as a result of drilling walls, wood and other surfaces. The principle of operation of the device is elementary, but no less effective. A rubber cover is put on the drill, which presses against the working surface that you drill, collecting all the produced debris into itself. Visually, the device is very similar to the dust cover of a car hinge, which once again confirms the Chinese ingenuity. Before installing the cover, a gasket is inserted, which is suitable for drills with a diameter of 6 to 14 mm.
