Abstract
A tool for machining of openings, shafts and the like has a body having concentrical stepped cylindrical working regions, grooves provided between the working regions, and transitional regions arranged between the grooves and the cylindrical working regions. The transitional regions extend substantially tangentially in a machining direction and a deformation process of an outer surface of the workpiece to be machined is performed without material removal by compression.
