Shock tools

The SOKOL Shock tool is engineered to dampen drill string vibrations caused by drilling. The shock tool design guarantees efficient operation under various combina­tions of impact loads on the bit and pressure drops in a drilling fluid.

Reliable belleville disk springs are used to reduce the vibration and ensure optimum tool rigidity and allow high impact loading to be applied to the shock tool.

Splined connection between the housing and the shaft effectively transmits torque during rotary drilling.

For maximum effectiveness, the shock tool should be placed above the mud motor during sliding and above the bit during rotary drilling.
