ABSTRACT OF THE DISCLOSURE A tool for processing the damaged tubes of a steam generator either to prepare the tubes for insertion of a sleeve, or to insert a sleeve, or to treat the sleeve after it is inserted, for example a drilling tool for drilling out plugs, a sleeving tool for inserting sleeves in the tubes, a high-roller tool for rolling the sleeves at their upper end where they have been expanded, or a low- roller tool for rolling the sleeves at their lower ends in the tube sheet, is suspended in the processing position by means of locking pins which engage tubes adjacent to a tube to be processed. The locking pins are driven into the adjacent tubes at a low velocity by a piston in a hydraulic cylinder under low pressure so that they are properly seated. Once seated, the pins are held by high pressure so that they resist the reactive forces of the processing.
