A machine for working rock, especially a block drilling machine, comprising at least one working tool, especially drilling tool. The drilling unit comprising the drilling tool is adapted to be connected to a supporting means in such a way that it has three degrees of freedom of rotation relative to the supporting means, which means it is movable, i.e. rotatable, relative to the supporting means about three axes which are respectively normal to each other. Furthermore the supporting means itself has at least two degrees of freedom of rotation relative to the ground. In particular, the supporting means can be pivoted about an axis which is approximately normal to the ground and an axis which is approximately parallel thereto, respectively.
