The provided method and material-removing tool serve for producing an exact-fit cylindrical bore with a high degree of surface quality and a length that may be a multiple of the diameter from an existing bore with a finishing allowance. In order to reduce the time taken for the finishing by means of a reamer to be performed, it is proposed to use a tool in the form of an impact die, which is formed at the front end with a circular or substantially circular cutting edge, the diameter of which corresponds to the nominal diameter of the bore to be produced, and which tapers from directly behind the cutting edge or behind a front region of a certain length.

A method and a device for facing surfaces of workpieces, in particular made of light metal alloys, in which a cutting tool is moved in a feed direction relative to the surface and removes material at a defined thickness by cutting, wherein the cutting tool is moved in a defined feed direction with one or more cutter bars oriented substantially parallel to the surface. The cutter bars are always set at an angle of <90 but >0 with respect to the feed direction. In this way, surfaces with high surface quality can be produced, in particular for workpieces made of light metal, with cost-effective machining parameters.
