3M 7000028224 Disc Backing Pad Quick-change Type R

Product Description

The 3M 7000028224 is a Quick-Change Type R disc backing pad designed to hold and drive abrasive discs in handheld rotary tools. Rated to a maximum of 6000 RPM, this firm-density pad measures 1-1/4 inches in diameter and uses a Roloc-style quick-change attachment system for fast disc swaps without tools. It is used by metalworkers, fabricators, and maintenance technicians for grinding, blending, and surface preparation tasks in production and field environments. Weighing 0.01 pounds, it adds minimal mass to the tool assembly.

This backing pad is suited for light-duty spot work, weld blending, and surface conditioning where a compact 1-1/4 inch pad is required. The Roloc quick-change interface is common in automotive body shops, HVAC sheet metal fabrication, and general metal finishing operations. It accepts standard Quick-Change Type R abrasive discs and is typically paired with die grinders or right-angle grinders equipped with a compatible mandrel.
