3M 7000045280 Disc Backing Pad Quick-change Type R

Product Description

The 3M 7000045280 is a Quick-Change Type R disc backing pad designed for use with rotary grinders and die grinders in metalworking, fabrication, and finishing applications. It accepts a 1/4-20 female thread for secure mounting to compatible tool spindles and supports a maximum operating speed of 30,000 RPM. The medium-density construction provides consistent support across the disc face, helping maintain even contact during grinding and surface conditioning work. This backing pad is installed by metalworkers, fabricators, and maintenance technicians who use quick-change abrasive disc systems on a regular basis.

This backing pad is suited for use with Roloc TR quick-change abrasive discs in light deburring, blending, and surface preparation tasks. It fits applications across automotive body work, general metal fabrication, and industrial maintenance environments. The quick-change design allows rapid disc swaps without additional tools, reducing downtime during multi-step finishing operations. It is appropriate for both shop and field use where a portable rotary tool with a 1/4-20 spindle thread is employed.

Installation Notes

Installation is performed by threading the backing pad onto the tool spindle by hand until snug — do not overtighten. Ensure the tool is fully powered off and disconnected from any air or electrical supply before attaching or removing the pad. Verify that the tool spindle speed does not exceed the 30,000 RPM rating of the pad before operation. Inspect the pad for wear or damage before each use and replace if the mounting interface shows signs of stripping or deformation.
