Abstract
A drilling and driving device provides, in combination, a drilling tool for drilling a borehole and a percussion attachment for driving fastening elements into the borehole. The drilling device includes a housing into which a drilling tool can be inserted. The percussion attachment is pivotally mounted on the housing so that it can be positioned over the drilling tool for driving the fastening element or it can be pivotally displaced so that the drilling tool can be used. In its displaced position, the percussion attachment can be loaded with a fastening element from a magazine located on the housing.
