An improved tool is provided for the removal of tubes from heat exchangers. First a mandrel is threaded into the end of a tube. The present tool is then fitted over the mandrel and is responsive to trigger-actuated hydraulic and/or pneumatic control means to automatically cause the tool to grip the mandrel and thereafter move the mandrel with its attached tube away from the tube sheet of the heat exchanger.
