Drilling method: Down-the-hole
Hole diameter: 138-165mm
DTH-hammer: 5 and 6 inches
● The SWDE series is surface down-the-hole drilling rigs which have a drilling diameter of 90-230mm and a max drilling depth of 36m.
● Meeting the drilling needs of vertical,inclined and horizontal blasting holes under various geological conditions, with high hole-forming efficiency, low energy consumption and environment-friendly skills.
● The unique one-click switching between down-the-hole mode and cutting mode allows drilling operations on both soft and hard rock stratum, which expands the application range, reduces construction costs and improves construction efficiency.
