Limited freshwater resources require a very careful attitude. This especially applies to their underground mining, carried out by constructing special wells. To a large extent, resource-saving in artesian drilling is achieved by increasing the accuracy of threaded connectors for drill pipes. The technology of manufacturing such threads is mainly carried out using turning operations. However, it would be more effective to use multi-point cutters rather than simple tools. The drill-string tapered thread model is obtained as a result of finishing one pass using four-thread comb turning. The study of the possibility of their application from the point of view of technological possibilities and especially the accuracy of the obtained thread is the object of research. The resulting calculated value of the longitudinal deviation does not exceed 0.012 mm, which is 10% of the tolerance. The conducted studies show the complete possibility of using turning multi-point cutting-tool for the manufacture of tool-joint threads, starting from their smallest nomenclature size.
