The purpose of operation - mining and intrusion of constructions of wear-resistant chisels for drilling wells by the equipment used in a coal industry of Ukraine. A method of research - analytical and experimental definition of design parameters of a drilling tool and regime parameters of drilling. Is carried out account of elements of a construction of chisels. The alpha tests of experimental samples of chisels are carried out with the purpose of definition of optimumparameters of drilling of wells by diamond tungsten carbide chisels. The experimental batch of chisels in an amount 20 pieces manufactured. An area of application - instrument for chisel machines used in a coal industry..
