Diamax 5″ Rigid Rubber Backer Pad

The Diamax 5″ Rigid Rubber Backer Pad is a heavy-duty backing plate engineered to provide maximum stability, durability, and control when using diamond polishing and grinding pads on stone surfaces. Designed for professional fabrication and installation environments, this rigid backer pad ensures consistent pad support for smooth, accurate results across all stages of polishing and surface preparation.

Constructed from high-quality, impact-resistant rubber with a reinforced internal structure, the rigid design minimizes flex during operation. This added firmness allows for better pressure distribution across the polishing pad, helping maintain flat contact with the surface for more even grinding and polishing. The reduced vibration improves operator control and enhances finish quality—especially important when working on flat surfaces, straight edges, and large slab areas.

The 5″ diameter makes this backer pad compatible with most standard variable-speed angle grinders and air polishers, allowing seamless integration into professional workflows. Its hook-and-loop (Velcro) face ensures secure pad attachment while enabling quick and efficient pad changes during multi-step polishing processes.

Suitable for use with diamond polishing pads and grinding disks, the Diamax Rigid Rubber Backer Pad performs reliably in both wet and dry applications. Wet polishing helps extend pad life and control dust, while dry polishing offers convenience for on-site adjustments and installations.

Ideal for countertop fabrication, edge work, slab preparation, and restoration projects, this backer pad enhances precision, improves consistency, and supports professional-quality results on granite, marble, quartz, engineered stone, and other hard surfaces.
