S59C型绳索取心冲击回转钻具（简称S59C型绳冲钻具）是与S59型绳索取心钻具配套使用的一种新型钻具。它综合了冲击回转钻具和绳索取心钻具的优点，是两者的有机结合。该钻具可用于口径为φ59mm、倾角为75°～90°、深为0～500m的钻孔中。该钻具适用于中硬以上岩层中钻进，尤其是对坚硬、致密、弱研磨性地层，可大幅度提高钻进效率，并能有效地减轻孔斜和岩心堵塞现象。从而提高了回次进尺长度和提大钻间隔，并且孔内事故减少，钻探费用降低。因此使用该钻具施工可获得良好的经济效益。
S59C Cord Coring Impact Drilling Rig (S59C Cordless Drilling Rig) is a new type of drilling tool that is used with S59 type rope coring drill. It combines the advantages of impact rotary drilling tools and rope coring tools, is the organic combination of the two. The drill can be used for the hole diameter φ59mm, angle of 75 ° ~ 90 °, depth of 0 ~ 500m drilling. The drilling tool is suitable for drilling in medium and above hard rock formations, especially for hard, dense and weak abrasive formations, which can greatly improve the drilling efficiency and can effectively reduce the hole inclination and the core plugging phenomenon. As a result, the length of the footage was increased and the drilling interval was increased, as well as reduced accidents in the borehole and lower drilling costs. Therefore, the use of the drilling tool construction can get good economic benefits.
