It's a down-hole air hammer mechanism for moving casing forward during drilling. The Eccentric Casing System can be retrieved once the desired depth has been reached, leaving the Water Well Casing in place for sampling or installations. Once the bore-hole has been completed, the casing can be retrieved and reused.
Casing System Usage:
1. The casing must be used when working with unstable rock formations.
2. For large hole boring, typically in water well drilling.
3. To control the hole well, it is best to drill no deeper than 40 meters.
4. Connect the 108mm casing tube and 3.5" hammer.
5. The air volume is 500 cfm and the pressure is 20 Bar.
6. The equipment is retrieved for use in the upcoming holes.
