Drilling Shock Tool

Extend Bit Life. Reduce Vibration.

Rubicon’s Drilling Shock Tool reduces direct impact on the drill bit, vibration in the BHA, harmonics in the drill string, and increases bit life and penetration rates. Designed with disc-springs for both heavy and lightweight drill strings, its oil lubrication reduces mechanical wear. A unique pressure compensation chamber allows for extended life in all drilling applications. It is adaptable for both in-string and nearbit locations and is effective in both tension and compression.
