Abstract
A honing tool for working several separate bores that are arranged coaxially in series and have different diameters. The honing tool includes several cutting bar groups arranged coaxially in series, wherein a diameter of a cutting bar group of the several cutting bar groups, which diameter is formed by radially extendable cutting bars, differs from a corresponding diameter of at least one other cutting bar group of the several cutting bar groups. A centering bar group is arranged in an axial direction to a free end of the honing tool adjacent at least one cutting bar group; or a guide bar group is arranged directly adjacent opposite the free end of the honing tool adjacent the at least one cutting bar group, or both the centering bar group and the guide bar group are arranged accordingly.
