In a machine for milling keys for lock cylinders with disc-shaped tumblers, consisting of a rotatable support, a key holder which on the one hand can be adjusted towards and away from the milling cutter and on the other hand can be set parallel to the axis of the cutter shaft by means of a screw drive, and also a device for setting the key holder about an axis, parallel to the cutter shaft, with preselectable angle of rotation, in order to achieve simpler manufacture of the key-milling machine and simpler manipulation of the same, the key holder consists of a straight bar (11) directed parallel to the cutter shaft (4), furthermore the screw drive is orientated coaxially to the bar (11) and is directly effective on the bar in the axial direction, in addition the bar (11) is mounted in such a way as to be positively rotatable to a limited extent by less than one revolution relative to its bearing arrangement, and several rotary limit stops (34) are provided which are held on the bar bearing arrangement, are distributed over the maximum rotary range of the bar (11), can alternatively be set against the bar (11) and can reduce the maximum rotary range. <IMAGE>
