  • Drilling Hydraulics - an overview | ScienceDirect Topics

    There is always some drop in performance as the length of the drill rod increases. Some of the energy is converted into heat in the material of the drill rod and there are losses at the screwed couplings. For underground drilling, water flushing is employed to clear out the drill chippings, but for surface drilling, air flushing is more usual.

  • Drill Rods | McMaster-Carr

    Drilling requires hydraulic power to be available at the bit, so the proper selection of bit nozzles and jet velocity will be provided to optimize the rate of penetration and lower overall drilling cost. Large pressure fluctuations due to drill string movement during trips (swab and surge) are to be avoided to prevent kicks or loss of circulation.
