Professional rigid aluminum backer pads deliver uncompromising stability for demanding grinding and polishing applications. CNC-machined from high-grade aluminum alloy, these backer pads provide a perfectly flat, rigid surface that eliminates flex during aggressive material removal. The precision engineering ensures zero vibration transmission and maintains consistent contact pressure across the entire working surface. Compatible with both angle grinders and air polishers, these rigid backer pads are the professional's choice for applications where surface flatness and stability are paramount.
