Tru-maxx TRU-RR204M Disc Backing Pad Quick-change Type R

Product Description

The TRU-MAXX TRU-RR204M is a 2-inch disc backing pad designed for use with Quick-Change Type R abrasive discs. It features a 1/4-20 female thread connection and a 1/4-inch shank diameter, rated to a maximum of 30,000 RPM. The medium-density pad construction supports consistent disc contact across the work surface. This backing pad is compatible with Quick-Lok quick-change disc systems and is the correct hardware for anyone running Type R abrasive discs on die grinders, straight grinders, or similar rotary tools in metalworking, fabrication, and surface prep applications.

This backing pad fits standard rotary tool setups used in metal fabrication shops, automotive body work, welding prep, and general surface finishing. It is intended for professional tradespeople and machinists who require a reliable, high-speed-rated pad for quick disc swaps without tooling changes. The Quick-Lok compatibility means discs can be mounted and released quickly, reducing downtime during multi-step grinding or finishing sequences.

Installation Notes

Installation is performed by machinists, fabricators, or tool operators familiar with rotary abrasive equipment. Before mounting or removing the backing pad, ensure the grinder is fully powered off and disconnected from its power source. Thread the pad onto the grinder spindle securely before attaching any abrasive disc, and confirm the disc RPM rating meets or exceeds the tool speed before operation. Always verify the abrasive disc is fully seated and locked into the Quick-Lok mechanism before starting the tool.
