Two soft sponge interface pads designed for 5 inch 125 mm hook and loop sanding systems. Use these pads between backing pads and sanding discs to improve contact on uneven surfaces, reduce vibration, and extend abrasive life. Key benefits Improved contact and edge sanding: Soft foam conforms to contours for closer, more even sanding at edges and curved surfaces. Reduced vibration: Cushioned interface lowers tool vibration for smoother operation and better finish. Longer disc life: Eight hole design helps clear dust from the work surface and reduces clogging of sanding discs. Fast changes: Hook and loop connection allows quick attachment and removal of sanding discs and backing pads.
