Downhole shock tool properties
    In case of rotary drilling the shock tool (ST) is placed above the bit, in case of PDM use, the ST is placed in BHA above the PDM
     Belleville springs dampen vibrations and ensure optimal ST rigidity for maximum load withstanding
     ST design ensures its reliable operation at various axial loads on bit and differential pressures
     Splined connection ensures reliable torque transfer
     
MAIN ADVANTAGES:
        increases BHA components life
     minimizes risk of BHA components failure
