3M 7000000442 Disc Backing Pad Quick-change Roloc

Product Description

The 3M 7000000442 is a quick-change disc backing pad designed for use with Roloc-compatible abrasive discs in grinding, blending, and finishing applications. Rated to a maximum of 10,000 RPM, this backing pad features medium density construction that provides consistent disc support across the work surface. It accepts quick-change disc attachments, allowing fast disc swaps without additional hardware. Weighing approximately 0.07 pounds, it is compact and lightweight for use with standard right-angle die grinders and pneumatic tools. This part is suited for metalworking, fabrication, and surface prep tasks performed by machinists, welders, and trade professionals.

This backing pad is used in light to medium-duty grinding and surface preparation work. Its medium density provides controlled flexibility during contour blending and flat surface finishing. The Roloc quick-change interface is compatible with 3M Roloc abrasive disc systems, enabling rapid disc changes during production or field work. Common applications include weld blending, rust removal, and paint stripping on metal surfaces. It is appropriate for both shop and field use wherever a right-angle grinder or die grinder is employed.
