Rigid rubber backing pads provide a stable, firm support for abrasive discs, making them ideal for heavy stock removal and achieving perfectly flat surfaces. Unlike flexible pads, which conform to contours, rigid pads apply concentrated pressure to the workpiece, allowing for more aggressive grinding and faster removal of material like weld seams.
Flexible rubber backing pads are essential for contour sanding, polishing and working on irregular surfaces where a rigid pad would cause gouging or uneven finishes. They typically feature a hook-and-loop (Velcro) or lock nut system and are compatible with angle grinders, sanders, or drills.
