The stand of research are executed at drilling a granite one layer diamond core bits by diameter of 59 mm. The researches are executed at various parameters of a mode of drilling and at various parameters pulse washing. Is established, that pulse the washing in 1,18-2,20 times raises mechanical speed. The design of the bottom breaker of a flow is developed of a drill liquid, on which the patent of Ukraine № 42174 А is received. Product Description popup.authors popup.nrat_date 2020-04-02 Close
