Product Description
Reverse Circulation (RC) drilling utilizes dual wall or dual tube drilling systems. Compressed air is forced down the annulus of the rod, entering the hammer and bit. Rock fragments crushed by the bit are collected into the inner tube through air holes on the bit head, then returned to the surface for sampling. Our RC hammers and bits are widely used in:
- Underground mining
- Quarry operations
- Hydraulic and hydro-power engineering
- Water well drilling
- Mineral exploration
- Anchoring hole drilling
- Geothermal engineering
- Subway excavation
- Civil engineering projects
