Reverse Circulation Drill Bits are used in hole drilling in mines, hydrology and water well, geothermal well, geothermal air conditioning well, geologic exploration, complicated gravel stratum, etc

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


1.Reverse Circulation bit is well known for its high wear resistance on medium-hard to hard abrasive rock formations .Featuring spherical tungsten carbide inserts that is known to have strong configuration against carbide fracture.

2.Recommended for eliminating hole deviation

3.Widely used drifting and tunneling

4.Bit face design is ideal for medium-hard to hard abrasive rock
