The KT12 integrated down the hole drill rig is driven by the Cummins China stage III diesel engine and the two-terminal output can drive the screw compression system and hydraulic transmission system. It is capable of drillingφ115-152mm vertical, inclined and horizontal holes, mainly used for open-pit mine, stonework blast holes and pre-splitting holes. 



The drill rig is equipped with the automatic rod handling system and lubricating module of drilling rod, resulting in one operator and fewer mining operations. The main control action is integrated to one handle, typical of user-friendliness. It is equipped with the anti-jamming system and optional drilling angle and depth indication are available, thus simplifying drilling and improving the drilling quality. The efficient dust-collecting system, spacious cab, high-powered air-conditioner and quality stereo system provide ideal conditions for operations, contributing to the highest working efficiency.

  • High Efficient Dust Collecting System


  • Good hydraulic system


  • Safe & Comfortable Cab


  • High Quality Walking Track
