System for producing bores in building walls for later laying of cables and-or pipelines

摘要

The system includes a force rotatable drilling head (12) rotating about an axis (42), with a drive shaft (20), and a non-rotatable housing (14), which receives the drive shaft of the drilling head. In addition, there is a clamping unit (16), the housing (14a,b) of which fixes a bushing (24) drawn into the building wall, or a product line to be drawn in. The housing receives a drive unit (28) for the rotation of the drilling head. The drive unit is operable using compressed air.
