The article describes the effect of boron, nitrogen, yttrium and hafnium ions on the modified BK10 (WС - 79.7% Co - 9.5% + CrN - 1.3% + AlN - 6.5% + TiN - 3%), BK20 (WС - 80.00%) and VK10 (WС - 90.00%) where the possibility of obtaining nanostructures is shown. It has been determined that: the value of the ion energy and the ion charge significantly affect the grain size with increasing energy and charge size; the grain size increases; an increase in the percentage composition of tungsten carbide leads to grain growth, and with an increase in the mass of the ion to an decrease in the grain size more significantly, which can be used to obtain the required grain size. Тhe design of the chemical composition of the cutting tool material, taking into account the possibility of nanostructure formation, shows that not always an increase in the share of tungsten carbide increases the efficiency and efficiency of the tool, and often the grain size has a decisive influence. The possibility of constructing the chemical composition of the basic material of the cutting tool with regard to its hardening due to the formation of nanostructures and nanocoating is shown
