The paper considers the creation of modern highly efficient cutting tools from polycrystalline superhard materials based on cubic boron nitride by forming the working surfaces of the cutting tools and changing the contact interaction conditions of the tool with the processed material for high-speed processing of hard-to-machine metals and alloys.

The authors of the scientific and technical work carried out the following: developed modern highly efficient cutting tools from polycrystalline cubic boron nitride (PcBN); additional methods of finishing tools from PcBN of BH and BL groups have been developed, depending on the operating conditions; force regularities of the cutting process and stability regularities of tools from PcBN groups BH and BL were determined; the performance of PcBN tools in the processes of high-performance processing of hardened steels and alloys, including under conditions of dynamic loads, was investigated.

The main result achieved is that the modified tools from PcBN of the BL group make it possible to effectively carry out finishing processing of iron-carbon alloys of high hardness at high cutting speeds, including with dynamic loads, while the intensity of tool wear is 1.5–2.0 times lower than in comparable to instruments equipped with PcBN with high content of superhard phase  (95–97%).
