Our eccentric drill bits are used for cased drilling in loose ground and varying ground formations. Expandable cutting elements enlarge the borehole diameter, allowing the casing to be advanced simultaneously with the drilling process.

Our eccentric drill bits offer:

-   Drilling and reaming in one operation
-   Simultaneous advancement of the casing
-   Various designs for different casing systems
