Frequently Asked Questions
What is the actual drilling depth capacity of the TWD400?
The TWD400 has a maximum rated drilling depth of 400 meters under optimal conditions. Actual achievable depth depends on formation characteristics.
Formation Type Achievable Depth
Soft formations (clay, sand, gravel) 300 - 400 m
Medium-hard rock 200 - 300 m
Hard rock formations 150 - 250 m
How do I choose between DTH hammer drilling and mud drilling?
Selection depends on formation type and project requirements.
Mud Drilling – Best for:
  • Clay, silt, sand, and gravel formations
  • Unconsolidated and soft formations
  • Situations requiring excellent borehole wall stability
DTH Hammer Drilling – Best for:
  • Medium-hard to hard rock formations
  • Faster penetration rates required (up to 10x faster than mud drilling)
  • Formations where mud circulation is difficult
Dual-Mode Advantage: The TWD400 can switch between methods during a single project as formations change, providing maximum flexibility.
How many operators are needed to run the TWD400?
The TWD400's centralized hydraulic control system enables single-operator drilling, significantly reducing labor costs.
Role Personnel Responsibility
Primary Operator 1 Control console operation, drilling process management
Assistant Workers 1-2 Drill pipe handling, casing installation, mud management
Total Crew 2-3 vs. 4-6 for traditional rigs
What is the delivery time?
Configuration Lead Time
Standard Configuration 7 - 15 days
Custom Configuration 30 - 45 days
Accessories & Spare Parts 3 - 7 days
