3M 7000028239 Soft Interface Pad 6 Inch x 1/2 Inch Backing Pad

The 3M Soft Interface Pad is a cushioned backing pad designed to work between your random orbital sander and abrasive discs. This foam interface pad helps prevent sanding marks and gouges while providing a more uniform finish on contoured or uneven surfaces.

Key Features:

• 6-inch diameter pad with 1/2-inch thick foam cushioning
• 3/4-inch arbor hole for secure mounting to sanders
• Soft foam construction absorbs pressure variations during sanding
• Reduces the risk of swirl marks and burn-through on edges
• Ideal for automotive refinishing, woodworking, and metal finishing applications
• Compatible with hook-and-loop (Velcro) backed abrasive discs

Interface pads are essential for achieving professional-quality results when sanding curved surfaces, body panels, or anywhere that maintaining consistent pressure is challenging. The soft foam layer allows the abrasive to better conform to the workpiece while protecting delicate surfaces from aggressive sanding action.
