Eccentric Casing System (ODEX BIT)
Applicables：
The surface of the stratum is mostly covered by loose material, sand and mud layers, backfill layers (without boulders), etc
Components：
Features：
The drill tool has a simple structure,high stability, and fast drilling speed. It adopts a unique locking system
structure, which makes the connection reliable and easy to disassemble. The
surface of the drill tool parts is strengthened and wear-resistant carbides are
installed on the back of the eccentric wheel to improve the wear resistance of
the drill tool.System composition：
1. When drilling starts, the reamer opens.
2. When drilling finishes, carefully reverse the drill and retract it from the tube.
3. The casing tube can be left in the hole or grouting can be done while the tube is being pulled out.
4. Use normal bit to drill to the desired depth.
Applications：
Water well
As the main tool for drilling water wells, eccentric drilling tools can ensure that drilling and wall protection are carried out simultaneously, which can significantly shorten the time to pass through the overburden.
Foundation support
Under geological conditions such as soil, silt and sand, when casing tubes are used for permanent or temporary wall protection, the eccentric drilling system is the fastest and most economical drilling tool system.
Anchoring
When it is necessary to reinforce the formation on the slope, the eccentric drilling system effectively meets the needs of the anchoring operation project.
