A plurality of scraper blades are pivotally supported circumferentially spaced about the tool on respective ones of the body members for engagement with the pipe to remove coating material therefrom as the tool is towed along the pipe. Toxic coating materials are removed during a process wherein a catcher frame is supported by the pipe and having a material-collecting hammock slung under the pipe for collecting toxic coating materials as the tool is towed along the pipe.
