Looking for an efficient and economical solution for overburden drilling? Look no further than our eccentric casing system.
This specialized drilling tool is equipped with an ejectable eccentric bit that can expand to the required diameter at the bottom of the hole.
In most geological conditions, the eccentric casing system is the most cost-effective way for well drilling and geothermal drilling. It is widely used in micro-pile construction, dam and port development, and small-scale grouting operations, making it a popular choice among construction teams. Thanks to its cleverly designed winged expansion bit, the drill head can be recovered and reused, making it more ideal than other similar drilling tools for shallow hole operations.
