A housing block for receiving valves, for example piston pumps and storage chambers for use in hydraulic vehicle brake systems. The invention uses a wobble tool to deform material of the housing block at a beginning of a hole essentially in the longitudinal direction of the hole, so that with the insertion of the wobble tool into the housing block in the vicinity of the beginning of the hole, first opening narrowed in relation to the diameter of the hole is produced. The hole becomes narrower with further continuation of the wobbling process and finally disappears. Then the material, which has produced the increased narrowing of the opening and finally its disappearance, forms a closure. The production of plug bodies in accordance with the prior art and the production of assembly devices are eliminated.
