As an unique drilling tool,the Hydraulic Impactor makes the hammer impact bits with high frequency through fluidics to bring both rotation and impact crushing results,by which rate of penetration (ROP) can be improved.


  • Suitable to hard formations,especially to those with drillability value over 4 and compressive strength over 100 MPa.
  • The property parameters can be adjusted through flow rate changes.
  • The life time of jet flow element lasts over 100 hours.
