Highlights
Drilling systems (such as SM-EX, Robit, ODEX and Super Jaw) designed to advance the borehole and install the casing in a single operation. Their mechanism lets the pilot assembly expand and pull the shoe along with the casing, ensuring immediate stabilization in fractured or unstable ground.
