Shock Absorber
Shock Absorber
Our double way shock absorber is a kind of oil drilling equipment used for simultaneously slowing down or eliminating the vertical or horizontal shock from drill string. It can greatly reduce the damage (caused by shock) to drill bit, drilling tool and surface drilling tool, and thus increase drilling speed and save drilling cost.
