Abstract
The reaming tool comprises a support spindle (10) which has a first fastening device (12) for a drill stem as well as a second fastening device (14) for a material to be drawn in, bores being provided in the support spindle for the supply of a drilling suspension. Furthermore, the reaming tool comprises a reaming body arranged on the support spindle (10) and having highly wear-resistant, abrasive members. The reaming body consists of at least two individual, disc-like reaming elements (16) of different diameter which are arranged at a mutual distance apart on the support spindle (10). <IMAGE>
