ABSTRACT:
A combination tool for machining a bore has a tool shaft transmitting a rotational movement and an oscillating movement in an axial direction of a bore to be machined with the tool. A horning tool is arranged on the tool shaft, and a deburring tool is arranged on the tool shaft at an axial spacing to the honing tool in a direction of a longitudinal axis of the tool shaft. The honing tool is configured to move for each honing stroke between a lower position and an upper position wherein a spacing between a lower edge of the honing tool and a lower edge of the deburring tool in the direction of the longitudinal axis of the tool is greater than a spacing of the lower edge of the honing tool to a workpiece surface when the honing tool is in the lower position.
