The invention relates to a tool for at least partially removing a coating or layer of a base body of a tube. The inventive drilling machine tool comprises a base body. At least one guiding element aligns the base body with the tube and defines a rotational axis for a rotational movement of the base body around the tube. A blade is linked with the base body with a degree of freedom in a direction radial to the rotational axis. The blade has a cutting edge which has an orientation parallel to the rotational axis. An activation element biases the blade in radial inner direction. When driven by a drilling machine, the drilling machine tool rotates around the tube located within the drilling machine tool, wherein the blade “peels” the coating or layer from the tube. |
