Concentric Overburden Drilling Systems

At the start of the drilling operation, the segments are in the closed position to allow the system to pass through the lead casing and seat against the casing shoe.

When drilling starts, the segments swing out to drill the hole to the desired diameter. The machines can be withdrawn through the casing by rotating the System anti-clockwise against the solid base of the hole or up against the casing shoe.
