3M 7100002305 Roloc Disc Pad 3 in 1/4-20 Internal

Product Description

The 3M 7100002305 is a hard backup pad designed to support 3-inch diameter Roloc abrasive discs during grinding, blending, and finishing operations. It features a 1/4-20 internal thread that mounts directly to power tools with a 1/4-20 external threaded shaft, or pairs with a Roloc shank adapter for use with collet chuck tools. Weighing just 0.13 pounds, this compact pad provides a rigid backing surface that helps maintain consistent disc contact and even material removal across the work surface. It is sold individually and is a standard component in Roloc disc setups used across metal fabrication, automotive bodywork, and industrial maintenance applications.

This backup pad is suited for use in metal fabrication shops, automotive refinishing bays, and general industrial maintenance environments. Technicians and fabricators reach for this pad when running 3-inch Roloc abrasive discs on die grinders and other rotary tools. The hard pad construction is appropriate for tasks that require firm, controlled disc pressure against flat or low-contour surfaces. It is compatible with the Roloc quick-change disc system, allowing fast disc swaps without tools.

Installation Notes

Installation is typically performed by the tool operator prior to disc use. Power down and disconnect the tool from its power source before attaching or removing the pad. Thread the pad securely onto the 1/4-20 external shaft of the die grinder or attach via the appropriate Roloc shank adapter for collet chuck tools.
