Eccentric Casing System (Odex Bit)

· 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 sol,slt and sand, when casing tubes are used for permanent or temporary wall protection, the eccentric drilling systems 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.

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.

Applicable formation: The surface of the stratum is mostly covered by loose material, sand and mud layers, backfill layers (without boulders), etc.
