摘要

The device has a tool unit (6) comprising a tool shank (8) and a tool head (7) and supported on a retaining unit (1) by a bearing unit (15). The retaining unit surrounds the tool shank, where the retaining unit engages the bearing unit on the shank at a region of a nodal plane of ultrasonics provided for operation. The tool unit is supported additionally on the tool head in another nodal plane, and an auxiliary bearing unit is detachably and fixedly provided on the retaining unit. The tool head is differently formed.
