ODEX/Eccentric equipment enables you to drill and case deep holes simultaneouslyin all types of formation, even those with large boulders.

The method is based on a pilot bit and eccentric reamer, which together drill a hole slightly larger than the external diameter of the casing tube. This enables the casing tube to follow the drill bit down the hole.

When using ODEX, part of the impact energy is diverted to the casing tube via a shoulder on the guide device, which in turn impacts a special casing shoe at the lower end of the casing.

Application Range

It is suitable for drilling water wells, geothermal wells, short micro piles,medium mini-type grouting hole of building, demand harbor project.

Operation Procedure

1.when the drilling starts, the wings swing out, and reams to drive the casing shoes and tubes into the hole.

2.When finished the drilling in overburden rock formations, reverse the drilling tools and the wings will get closed, and the drilling tools can be raised from the hole.

3.Next construction can be followed.
