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.
A honing tool (31) for working several separate bores (17a,17b, 17c) that are arranged coaxially in series and have different diameters, wherein the honing tool (31) comprises several cutting bar groups (3, 4, 5) arranged coaxially in series, wherein a diameter of a cutting bar group (3, 4, 5) of the several cutting bar groups (3, 4, 5), which diameter is formed by radially extendable cutting bars (18), differs from a corresponding diameter of at least one other cutting bar group (3, 4, 5) of the several cutting bar groups (3, 4, 5), characterized in that
A combination of a first honing tool (31.1) and a second honing tool (31.2) for working several separate bores (17a, 17b, 17c) that are arranged coaxially in series and have different diameters, wherein a first honing tool (31.1) comprises several cutting bar groups (3, 5) arranged coaxially in series, wherein a diameter of a cutting bar group (3, 5) of the several cutting bar groups (3, 4, 5), which diameter is formed by cutting bars (18) which can be radially extended, differs from a corresponding diameter of at least one other cutting bar group (3, 5) of the several cutting bar groups (3, 4, 5), wherein the at least one cutting bar group (3, 5) of the first honing tool (31.1) is designed and arranged so that at least one through bore (17a, 17c) can be worked by the at least one cutting bar group (3, 5), wherein the second honing tool (31.2) comprises a respective cutting bar group (4) of the several cutting bar groups (3, 4, 5), that two guide bar groups (6, 8) are provided coaxially and at an axial distance to the respective cutting edge group (4) that corresponds to an associated axial distance of the several cutting bar groups (3, 5) of the first honing tool (31.1).
