SOLLROC (Reverse circulation) RC hammers and drill bits for DTH drilling

RC hammers and bits are used in hole drilling in mines, hydrology and water well, geothermal well, geothermal air conditioning well, geologic exploration, gravel stratum, etc 

Especial suitable for complicated formation (Formation loose, difficult to drilling and unstable of hole wall), exhausting for deep hole, environment protection.

- Manufactured using premium hardened metals for long life;
- Maximum material recovery, up to 98%;
- No cross contamination of samples;
- Handles injection of water, foam, oil, and polymers without performance loss;
- Delivers maximum drilling under water.
