The tool specifically utilized for the removal of Babbitt metal from Babbitt bearings is a bearing scraper. Bearing scrapers are designed with a sharp edge that can precisely remove soft metals like Babbitt, which are used in bearing applications for good wear resistance and low friction characteristics. These scrapers allow for careful and controlled removal, ensuring that the bearing surface can be properly prepared for re-babbitting or maintenance.

Using a bearing scraper helps maintain the integrity of the bearing housing while allowing for a clean removal of the old material. This is important for ensuring that the new Babbitt material can bond effectively and provide optimal performance in the application.

In contrast, other options like chisels, files, or sanding tools are not specifically designed for this purpose. A chisel might damage the bearing surface or create uneven removal, while a file is typically used for smoothing or shaping, not for removing large amounts of soft metal. Sanding tools could also create a rough surface or contaminate the area with abrasive materials, which is not ideal for bearing applications. Therefore, the bearing scraper is the correct choice for this task.
