Abstract: The paper presents the main problems related to the manufacture of metallic-diamond tools.Until the early 1950s the developments in diamond tools were relatively slow. In that period only natural diamond crystals were available. Much faster developments in the tool manufacturing technology was caused by development of the production of synthetic dia-monds. Cobalt is using as a based material used for matrix of metallic-diamond tools for cutting of natural stones. Cobalt is characterizining a very special retention of diamond particles. The diamonds are held firmly by the cobalt matrix. In the new millennium the market for diamond tools continues to grow rapidly. The possibility of substitution of cobalt with the other cheaper alloys was considered. Producers are looking for materials give similar utilizing properties. The analysis of dynamics of mining, production and prices of industrial diamonds and cobalt was performed during 1935-2013 years.
