4-inch Rigid BackPlate for Diamond Abrasives provides a stable, flat backing for standard 4" hook-and-loop diamond pads. The rigid construction minimizes pad deflection during grinding and polishing, helping achieve even material removal across flat surfaces, bevels, edges, and tight countertop spaces. The backplate features a standard 5/8-11 threaded arbor for direct mounting on most angle grinders used for granite, marble, and concrete, enabling straightforward setup with common diamond pads. This combination of rigidity and compatibility supports consistent results in professional stone fabrication and surface maintenance. Features & Specifications Diameter 4 inches. The rigid body minimizes pad deflection to maintain flat contact across edges and bevels. Attachment System Hook and loop (Velcro) surface enables fast pad changes. Pads stay securely held in place during grinding. Arbor Compatibility 5/8-11 threaded arbor mounts directly onto most commercial angle grinders and polishers. Target Substrates Granite, marble, and concrete surfaces for grinding, shaping, and polishing. Weight 0.5 lb.
