These hook and loop backed 50mm diameter abrasive discs have a 6mm thick soft foam cushion. This cushion allows the abrasive to adapt precisely to any slight curvature of the worked surface. The silicon carbide abrasive is long lasting due to a net structure, which helps prevent clogging. These pads are designed for fine sanding and are especially useful for small automotive repairs or restoration. Supplied in a pack of 6 discs.
