RC drilling utilizes Dual Wall or Dual Tube Drilling technology. The system employs two rods with inner and outer tubes, where air is blown down the annulus of the rod to enter the hammer and bit. Rock fragments crushed by the bit are collected into the inner tube via air holes on the bit head and returned to the ground for sampling. Our RC hammers and bits are widely used in:

• Underground mining and quarries
• Hydraulic and Hydro-Power Engineering
• Water well drilling and mineral exploration
• Anchoring hole drilling and geothermal engineering
