ABSTRACT:
A two-piece housing is provided with several bores (3, 4) which extend through the two housing sections (1, 2). Each bore (3, 4) is concentrically surrounded by a centering in each housing section (1, 2), which is in the shape of an internal centering in one housing section and an external centering in the other housing section. These bores (3, 4) are manufactured in each housing section (1, 2) together with the respective concentrically surrounding centering and in one process step with a drilling tool which includes two cutters (8, 9, 10) adapted to the diameters of the bore and the centering respectively. Subsequently, the housing sections (1, 2) provided with the bores (3, 4) and centerings are assembled in such a way that the centerings fittingly interengage. (FIG. 1)
