Shock Sub has been
designed and proven to significantly reduce axial and torsional vibration between the
rotary head and drill string.
The shock and vibration generated through the drilling
action are effectively absorbed through a series of field replaceable shock elements. The
entire unit is sealed to protect it from gearbox oil and drilling debris.
Shock Subs is available for drill rigs using 3 1/2" to
8 5/8" drill rods.
