3M 7000045681 Disc Backing Pad Quick-change Type R

Product Description

The 3M 7000045681 is a Quick-Change Type R disc backing pad designed for use with rotary grinders and abrasive finishing tools in metal fabrication, welding, and surface preparation applications. It features a soft density construction and a Roloc TR quick-change interface, allowing rapid disc swaps without tools. Rated to a maximum of 8,000 RPM, it is suited for controlled material removal and blending operations. Grinding and fabrication professionals install this pad as the interface between the tool spindle and abrasive discs in production and repair environments.

This backing pad is used in industrial and trade settings where quick disc changes are needed to maintain workflow. The soft density backing conforms slightly to irregular or contoured surfaces, making it appropriate for finishing passes and blending welds or seams. It is compatible with Roloc TR quick-change abrasive discs and fits standard rotary tools that accept the Type R mount. Typical users include metal fabricators, welders, automotive body technicians, and maintenance professionals working in shop or field conditions.
