<p>Apparatus and a method for cleaning the inner surface of a well bore tubular comprises a body having an axis and an axial bore through the body, suitable for connection into a tool string for use in a well bore tubular, and a cleaning device, a stabiliser and typically a junk catcher arranged on the outer surface of the body. The stabiliser is adapted to resist radial compression and is rotatably mounted on the body. The stabiliser is rotationally mounted on bearings on the body. The stabiliser has an arrangement of blades that extend outwardly from the body. The stabiliser can typically have at least one magnetic device to attract and retain ferrous metal particles.</p> |
