Abstract: A cooling attachment can be releasably fastened to a work machine, which has a shaft in which a rod-like tool is guided with a rotary or hammering action and exits the shaft at a free end. The cooling attachment has a housing that encloses the work machine and in particular the shaft thereof and the tool that exits it, the latter only partially. Formed within the housing is a first cooling channel for conducting a coolant from an inlet opening to the tool exiting the free end of the housing shaft. In order to improve the cooling of the tool without cooling the workpiece to be machined, at least one connecting hole is provided, at the free end of the housing shaft, between the first cooling channel and a second cooling channel, in order to divert the coolant from the first cooling channel into the second cooling channel.
