Key Features
The dual motors rotate the drill bit with higher torque and speed, which can meet the drilling needs of 76 mm drill rod and 130 mm drill bit diameter.
High-quality crawler and piston engines provide more reliable performance and better maneuverability, allowing open-pit mining drilling operations to better adapt to complex ground conditions.
The central control panel is easy to use, which improves the efficiency, safety and comfort of drilling operations.
The new leveling function gives the machine stronger climbing ability and all-terrain performance, enabling it to adapt to various construction environments more effectively. The 420 model can also drill vertical holes on slopes to meet various construction needs.
