1. Device (1) for making drillholes (15) with an undercut (18), especially in cladding panels (2). …2.1 Such a device (1) consists of an adaptor (13) receiving the drilling tool (14) and connected to a drilling machine (11) in a torque-transmitting manner, and of a bearing bush which is fastened in a mounting (5) of a stand (3) and in which a guide sleeve (9) connected firmly to the drilling machine (11) is received and mounted rotatably and pivotably via a pivot bearing. …2.2 In order to achieve an automatic machine-controlled deflection by means of this device (1), there is fastened to the drilling machine (11) and guide sleeve (9) a wobble plate (12), on which engage a plurality of cylinders (16) which are arranged on the mounting (5) concentrically about the centre axis of the guide sleeve (9) and which are activated and actuated in succession in order to generate the wobbling movement for grinding out the undercut (18). ……
