1. An end file for a motorized rotating drill tip, said endofile comprising: a connecting element for connecting to a drill tip, a central longitudinal flexible core comprising a central flexible cable supported at the end of the drill tip by said connecting element, spirally wound wire at least partially surrounding the wire core and passing to the tip of the core opposite the end facing the handle; moreover, the tip of the core is beveled and not connected and stands for a spiral-wound wire at the tip; characterized in that the core includes a plurality of outer cores wound around a central flexible cable in a winding direction such that during use, when the file is rotated in a direction opposite to the specified winding direction, and the file is simultaneously removed from of the root canal, the outer cores are unwound and opened to form a brush. 2. The endofile according to claim 1, characterized in that the outer cores are wound opposite to the spirally wound wire so that when the file rotates in the direction of winding the spirally wound wire, it is tightened, and the outer cores are unwound. 3. An endofile according to claim 1 or 2, characterized in that the spirally wound wire is wound with a variable pitch along its length, so that different parts of the spirally wound wire have a different pitch. The endofile according to claim 1 or 2, characterized in that the inner central flexible cable of said core includes a plurality of inner cores twisted together around a central flexible wire in the first1.
