Dewalt DAMR3FXX01 Disc Backing Pad 3 Inch Quick-change

Product Description

The DEWALT DAMR3FXX01 is a 3-inch quick-change disc backing pad designed for use with right-angle grinders and die grinders equipped with a 1/4-inch shank. It accepts Roloc-style quick-change abrasive discs, allowing fast disc swaps without tools. Rated to 20,000 RPM, this backing pad is built for grinding, blending, and surface preparation tasks across metal fabrication, welding cleanup, and general maintenance work. HVAC technicians, pipefitters, and sheet metal workers commonly reach for this type of accessory when finishing ductwork, pipe joints, or structural components.

This backing pad suits light industrial and trade applications where quick disc changes improve workflow on the job site or in the shop. The Roloc-compatible interface makes it compatible with the broad range of 3-inch quick-change abrasive discs available from multiple manufacturers. It is a single-unit replacement item, making it a practical spare for kits or tool bags where a worn pad needs direct swap-out without purchasing a full accessory set.
