Abstract
A device for producing drilled holes with an undercut in facing panels includes a drill bit with a drill head that produces an undercut, and a drilling table for supporting a facing panel in which the drilled holes with an undercut are to be produced and displaceable in a plane of the drilling table. A trunnion projecting from a rotatable base member and engaging a bearing secured to the drilling table is movable between a first position in which the trunnion axis coincides with the axis of rotation of the base member, and a second position in which the trunnion axis is eccentric to the axis of rotation of the base member to effect swiveling of the drilling plate when the rotatable base is driven rotatably. The device has a mechanism for moving the trunnion between the first and second positions including a lever pivotally mounted on the base member, the trunnion being mounted on the lever, and a piston-cylinder drive secured to the base member for pivoting the lever.
