Abstract of the Disclosure Continuously revolving percussion drilling machine, which comprises a body and a drill shank mounted rotatably and axially slidably in the body for causing impacts on the drill rod. An impact mechanism is positioned in the body for causing axial impacts on the drill shank. A rotating device is provided for rotating the drill shank around its axis. The drill shank is provided with a toothing which is coupled in direct engagement with a toothing revolving in relation to the drill shank and rotating the drill shank. The toothing of the drill shank is axially displaceable in relation to the rotating toothing, so that the contact surfaces of the teeth of the toothing on the drill shank and of the toothing rotating the drill shank revolve and are exchanged constantly and teeth operate as cold and well lubricated. The rotating toothing may be a cogwheel or a tooth rim.
