What is a backing pad used for in grinding?

A backing pad is specifically designed to provide a stable surface for attaching sanding discs or buffing pads. This allows for improved performance during the grinding or sanding process, as it helps to distribute pressure evenly across the disc or pad, enhancing both effectiveness and safety. The backing pad ensures that these abrasive materials are securely held in place while allowing for flexibility and movement during use, which is crucial for achieving smooth finishes and effective material removal. When using power tools for grinding, the backing pad plays a vital role in supporting the attachment and optimizing the tool's functionality.
