King Cobra Shock Sub

Drilling into solid rock formations produces incredible high-frequency vibrations. The resulting load on the drill string not only causes premature equipment failure, but it can damage the borehole—both of which inflate the drilling cost per foot. Download our checklist as a quick reference.

Shock subs are blast hole drilling tools engineered to absorb the vibrational impact of surface mining. By protecting the drive heads and mast from the damage caused by axial and torsional shock vibration, the shock sub prolongs the life of drill components, improving run length and keeping downtime to a minimum. It also holds the drill bit in place, allowing a better penetration rate while protecting the expensive motor from bounce-out damage. All of this translates into a lower drilling cost per foot and a more productive operation.

Past dampening methods offered only minor vertical cushioning, prompting Utex engineers to develop a more effective shock sub. Impact and vibration reduction sub technology has been reengineered to provide radial stress relief as well as a better vertical cushion. This allows the shock absorbers to reduce accelerations induced at the drill head by as much as 65%, according to an independent field study. The result: a boost in productivity throughout the entire drilling process.

How Shock Subs Innovate Modern Drilling

Our latest infographic takes an in-depth look at shock subs and their importance to modern drilling.

It shares information on how shock subs reduce severe vibrations that are otherwise transmitted into the rotary head, drill tower and related components.
