Abstract
The invention relates to a superfinishing tool having a shank (2), as well as at least one rigid cutting edge (16) and at least one guide rib (30) on the periphery. In addition, or alternatively, the cutting edge (16) and/or the guide rib(s) (30) can be configured to form a single-piece solid tool with the shank (2). The guide beads or ribs guarantee steady, stable functioning of the tool in spite of high rotational speed and/or hardness of the workpiece. An additional advantage is provided by producing the tool as a solid tool, i.e. made of solid hard metal.
