Diamax-3" Soft Rubber Backer Pad

Diamax Cyclone 3″ Soft Rubber Backer Pad (SKU BP30) The Diamax Cyclone 3″ Soft Rubber Backer Pad (SKU BP30) is a professional-grade support tool designed to enhance the performance of Velcro-backed polishing and grinding pads on natural and engineered stone surfaces, including granite, marble, quartz, and engineered stone. Constructed from soft, flexible rubber, this backer pad provides controlled flexibility, allowing it to conform to curves, ogee profiles, bullnose edges, and other decorative or contoured surfaces. This flexibility ensures that polishing pads maintain consistent contact with the stone, preventing uneven finishes and reducing the risk of over-grinding on intricate details. Its 3″ diameter is optimized for precision work in tight spaces, edges, corners, and small radius areas, making it ideal for sink cutouts, detailed edge profiles, and inside radii where larger, rigid backer pads cannot reach effectively. The pad’s hook-and-loop Velcro attachment allows for quick, secure, and tool-free pad changes, improving workflow efficiency in fabrication shops or on-site installations. The soft rubber construction absorbs minor vibrations during polishing or grinding, providing a smoother, more controlled surface finish, particularly when used with resin, metal-bond, or hybrid polishing pads. It is suitable for both wet and dry applications, giving operators flexibility depending on the task and stone type. Wet polishing helps cool the pad, reduce dust, and extend the life of the polishing discs, while dry use can be effective for lighter surface finishing or shaping tasks. Compatible with 5/8″‑11 threaded angle grinders, air polishers, and water-fed polishing machines, the BP30 is versatile and integrates seamlessly into professional stone fabrication and finishing workflows. It is particularly valuable for stone fabricators, countertop installers, and restoration specialists who require precise control and consistent results on curved, decorative, or hard-to-reach surfaces.
