Which tool is used to remove the outside coating from the surface of materials?

The use of a Scotch-Brite pad on a drill motor is effective for removing an outside coating from the surface of materials due to its non-abrasive nature combined with its ability to conform to the surface being worked on. Scotch-Brite pads typically contain a nylon web that is impregnated with abrasives, making them suitable for cleaning and surface preparation without damaging the base material underneath. This method allows for a thorough cleaning and can be used to remove coatings such as paint, varnish, or oxidation without leaving deep scratches, making it a preferred choice in aerospace applications where surface integrity is critical.

In aerospace work, maintaining the material's characteristics while ensuring the removal of coatings is essential for subsequent processes, such as bonding or painting. The compatibility of the Scotch-Brite pad with various materials and coatings enhances its utility in industrial settings. Additionally, the use of a drill motor increases efficiency, allowing for quicker operations while ensuring a consistent finish on the surface.
