3M 7000045287 Disc Backing Pad Quick-change Type R

Product Description

The 3M 7000045287 is a hard-density disc backing pad designed for use with Quick-Change Type R abrasive discs in grinding, finishing, and surface preparation applications. The pad features a 3/8-24 female thread mount and is rated to a maximum of 20,000 RPM, making it compatible with high-speed pneumatic and electric right-angle grinders and die grinders. It accepts Roloc TR quick-change discs, allowing fast disc swaps without tools. Weighing 0.29 pounds, this backing pad is a compact, durable component built for repeated use in production and maintenance environments. Installation and disc changes are handled by metalworking and industrial maintenance technicians.

This backing pad is suited for metal fabrication, weld blending, deburring, and surface conditioning tasks in both shop and field settings. Its hard-density construction provides firm, consistent support across the abrasive disc face, which is preferred for work on flat or slightly contoured surfaces. The Roloc TR quick-change interface reduces disc changeover time, making it practical in high-volume or multi-step finishing operations. It is appropriate for use in light industrial, manufacturing, and MRO maintenance environments.

Compatibility

Designed for use with Roloc TR Quick-Change Type R abrasive discs. Mounts to grinders and die grinders equipped with a 3/8-24 threaded spindle. Verify tool spindle thread and RPM rating before use.

Installation Notes

Installation is performed by metalworking technicians or industrial maintenance professionals. Power down and disconnect the tool from its air supply or electrical source before attaching or removing the backing pad. Thread the pad securely onto the tool spindle by hand before operating. Do not exceed the 20,000 RPM maximum rating of the backing pad, and ensure the abrasive disc mounted to the pad carries an equal or higher RPM rating.
