Drilling method: Down-the-hole
Hole diameter: 105-165mm
DTH-hammer: 4 and 5 inches
●The SWDR series is surface down-the-hole drilling rigs which have a drilling diameter of 105-203mm and a max drilling depth of 30
●Meeting the drillingneeds of vertical, inclined and horizontal blasting holes under various geological conditions, with high hole-forming efficiency, low energy consumption and environment-friendly skills.
●The uniqueone-click switching between down-the-hole and cutting mode allows drilling operations on both soft and hard rock stratum, which expands the application range, reduces construction costs.
