3M 7000045281 Disc Backing Pad Quick-change Type R

Product Description

The 3M 7000045281 is a disc backing pad designed for use with quick-change abrasive discs in grinding, blending, and finishing applications. It features a 1/4-20 female thread mount and a medium-density construction that supports consistent disc contact across the work surface. Rated to a maximum of 12,000 RPM, this backing pad is built to handle sustained rotary tool use in production and maintenance environments. It accepts Roloc TR quick-change discs, allowing fast disc swaps without tools. Fabricators, metal finishers, and maintenance technicians working with angle grinders or die grinders will find this pad suited to both shop and field use.

This backing pad is intended for use with quick-change Type R and Roloc TR compatible abrasive discs in metal fabrication, weld blending, surface preparation, and finishing operations. It is applicable to both light production and heavy maintenance tasks where rapid disc changes and consistent backing support are required. The medium density construction suits flat and moderately contoured surfaces in shop environments.

Installation Notes

Installation is performed by threading the 1/4-20 female mount onto the spindle of the grinder or die grinder — ensure the tool is powered off and disconnected from the power source before mounting or removing the pad. Do not exceed the 12,000 RPM maximum speed rating of the pad or the attached abrasive disc. Inspect the backing pad for cracks, deformation, or wear before each use and replace if damage is found.
