Аннотация: Relevance. Requirements for rock cutting tools are to ensure high mechanical speed, resource, wide range of application and low material costs for its purchase. In other words, the drilling tool must be durable, wear-resistant, and made of relatively inexpensive material. Advances in the synthesis of polycrystalline diamond and the manufacture of high-strength cutters from it have significantly expanded the capabilities of drilling tool manufacturers. Synthetic superhard material began to be used in the manufacture of cutting elements and the entire working part of rock cutting tools. Innovations in materials science have made it possible to produce PDC cutters of various shapes, sizes, strengths, which is especially important when creating bits, crowns and drill heads with combined weapons. As is known, the composition and sintering conditions of the composite affect the properties of the resulting PDC cutter blank. By changing the strength parameters and the geometry of the PDC cutting elements, taking into account the field of application of the tool, you can achieve the best effect of rock breaking. Thus, when creating a new drilling rock cutting tool, it is relevant to combine knowledge and skills in the field of chemistry, materials science and design, which will lead to obtaining a promising rock cutting tool. The aim of the research is to determine the directions of improving the PDC-type drilling tool, namely, the possibilities of materials science in the field of sintering of superhard PDC material, the advantages of using a composite of various structure in the engineering of new designs of PDC-type drilling tools. Objects: composition of material, sintering process and obtained properties of PDC cutters, design features of PDC drilling tools. Methods: analytical research, experiment, analysis. Results. Changing the structure of the composite allows you to adjust the strength properties of the resulting PDC cutter. Addition of such a material as graphene increases the strength, thermal and electrical conductive properties of PDC cutter. Combining the capabilities of materials science and design experience makes it possible to achieve positive results in the development of a new promising rock cutting tool. Relevance. Requirements for rock cutting tools are to ensure high mechanical speed, resource, wide range of application and low material costs for its purchase. In other words, the drilling tool must be durable, wear-resistant, and made of relatively inex
