DXL421T Integrated DTH Drill Rig
Compact Integrated Drilling Solution For Mining And Rock Excavation

The DXL421T Integrated DTH Drill Rig is a professional-grade surface drilling machine developed for contractors, mining companies, and quarry operators who require efficient, flexible, and cost-effective rock drilling equipment.

Designed with advanced Down-The-Hole (DTH) drilling technology, the DXL421T combines a powerful drilling system with an onboard air compressor, hydraulic control system, crawler undercarriage, and dust removal system into a single mobile platform. This integrated structure eliminates the need for external compressor connections, reduces setup time, and improves overall drilling efficiency.

Compared with traditional separated drilling rigs, the integrated design provides better energy utilization, lower transportation costs, easier operation, and simplified maintenance. The machine is especially suitable for small and medium-scale mining operations, quarry production, slope reinforcement, road construction, and foundation drilling projects.

With reliable performance, compact dimensions, and excellent off-road capability, the DXL421T Integrated DTH Drill Rig provides an ideal solution for modern surface drilling applications.
