DXL920 Separated DTH Surface Drill Rig
Professional Surface Drilling Equipment For High-Efficiency Rock Drilling

The DXL920 Separated DTH Surface Drill Rig is engineered to deliver reliable and efficient drilling performance for today's demanding mining, quarrying, and construction industries. Combining advanced Down-The-Hole (DTH) drilling technology with a robust crawler platform and intelligent hydraulic control system, the DXL920 is designed to maximize productivity while minimizing operating costs.

Surface drilling projects require equipment capable of producing accurate blast holes under challenging geological conditions. The DXL920 achieves this through its powerful rotary drive, efficient feed system, durable boom structure, and stable hydraulic performance. Whether drilling in granite, basalt, limestone, marble, or other hard rock formations, the machine maintains excellent penetration rates and drilling accuracy.

The separated configuration allows the drilling rig and air compressor to operate independently, offering greater flexibility for transportation, maintenance, and equipment matching. Contractors can select compressors based on specific project requirements, improving utilization while reducing ownership costs.

The DXL920 is widely used in open-pit mines, aggregate quarries, road construction, railway projects, hydropower developments, municipal engineering, and infrastructure construction projects around the world.
