Standard Abrasives 7000121637 Disc Backing Pad

Product Description

The STANDARD ABRASIVES 7000121637 is a Quick-Change Type S disc backing pad designed to hold and drive quick-change abrasive discs in grinding, blending, and finishing applications. Fitted with a 1/4 inch shank, it mounts directly into pneumatic or electric die grinders and similar rotary tools. The pad is rated to a maximum of 40,000 RPM and features medium density construction, providing controlled flex and consistent disc contact across the work surface. Metalworkers, fabricators, and maintenance technicians typically install and operate this backing pad during surface prep, weld blending, and deburring tasks.

This backing pad is suited for light to medium industrial and fabrication environments where quick-change abrasive disc systems are the standard workflow. The SocAtt quick-change compatibility means it accepts discs designed for that attachment system, allowing fast disc swaps without additional hardware. It is commonly used with angle grinders, die grinders, and similar rotary tools in both shop and field settings.
