- The Foam Interface Pad is made of soft and durable foam that easily sands contoured surfaces while minimizing burn through. - The sponge interface pad adds support to the disc pad for improved abrasive cutting and tighter edge sanding, ideal for uneven surface finishes. - The sponge interface pad reduces vibration of the orbital sanding tool, helping to prevent the sander from jumping and biting, and it improves sanding results on a variety of items. - A 5" interface pad with 8 holes for efficient dust collection keeps surfaces clean and helps maximize wheel performance and extend wheel life. Applications: - Sand curved furniture edges and contours, such as chair legs or cabinet trim, where conforming contact reduces burn through. - Smooth uneven surfaces, door frames, moldings, and other irregular shapes for tighter edge control. - Dust-conscious sanding during prep for paint, stain, or finishing to maintain a cleaner work area and prolong abrasive wheel life.
