ABSTRACT:
A cutting and recovery tool for a well-head, having a housing which is adapted to engage with a side wall of the well-head to lock them together, and a mandrel extending through the housing and rotatable relative to the housing and adapted to carry a radially-acting cutter which severs the well-head below the area of engagement of the housing. This allows the well-head to be severed and withdrawn in a single operation.
