It was defined that the introduction of CrB2 in drilling inserts (diamond system WC-Co) and diamond-carbide inserts (diamond system WC/Co) in the necessary amount and right combination of sintering parameters of tracks provides a significant increase in wear resistance of the composites in comparison to composites prepared by industrial technology. Based on these prototypes, composites of drilling tools with improved performance characteristics have been developed.
