FIELD: metallurgy.
SUBSTANCE: charge based on tungsten carbide of two-size fractions, i.e. below 3 mcm and 4-30 mcm, and containing cobalt is mixed separately with plasticiser. Then, said components are mixed. Note here that charge of fraction approximating to 2 mcm makes 20% to 80% of total content. Produced charge is compacted and sintered.
EFFECT: improved working properties of cutting tools.
