This article describes the results of studies on methods for increasing the reliability of  mechanical process operations of hard-to-machine materials . Technological system is treated as a combination of factors affecting the treatment process. The article estimates an impact of factors such as a choice of the tool material, applied technology environment, processing modes on the reliability of technological operations. For different workpiece materials ( steel and corrosion resistant alloys, tungsten, etc. ) it describes the conditions under which tool life increases and a coefficient of variation reduces.
