Backer Pads

Backer pads for mounting diamond polishing pads on angle grinders and polishers. Backer pads provide the hook-and-loop (Velcro) interface between your grinder spindle and your polishing pads, allowing fast pad changes between grits. A quality backer pad keeps polishing pads centered, flat, and securely attached during use.

We carry rigid, semi-rigid, and flexible backer pads in standard sizes to match your polishing pad diameter and your grinder thread size. The right backer pad flexibility affects polishing performance on flat surfaces versus curved edges and profiles.

• Hook-and-loop surface for fast pad changes
• Rigid, semi-rigid, and flexible options
• Standard sizes: 4", 5", and other common diameters
• Threaded arbor fits standard angle grinders and polishers
• Keeps polishing pads flat and centered for consistent results

Match the right backer pad to your polishing application for the best finish quality on every job.
