Abstract

The drilling and chiselling tool has a percussion mechanism and a tool holder (10) for receiving tools. Impacts from the percussion mechanism are transmitted to the tool via a ram (4). The ram (4) can be connected to a switching member (7) by means of a locking element (6), this switching member (7) being axially displaceable via an actuating means (8). The axial displacement of the switching member (7) serves to shift the ram (4) into an impact-inoperative position. <IMAGE>
