FIELD: technological processes.
SUBSTANCE: instrumental joint comprises the first component and the second component having one cutting section and pressed to the first component by means of a clamping screw. The second component comprises a mounted surface with three covered engaging elements coupled with three covering engaging elements made in a mounting surface of the first component. Each of three covering engaging elements comprises two groups of side surfaces located on the common section, at the same time the common section has mirror symmetry relative to the first plane, and each group of side surfaces comprises two opposite surface sections separated by the first plane. Only one of two surface sections in each of two groups of side surfaces is in clamping contact with the appropriate support surface of each of three covered engaging elements.
EFFECT: improved manufacturability of production.
