Tru-maxx TRU-RR204H Quick-change Type R Disc Backing Pad

Product Description

The TRU-MAXX TRU-RR204H is a hard-density disc backing pad designed for use with quick-change Type R abrasive discs. It features a 1/4-20 female thread and a 1/4-inch shank diameter, accepting standard quick-change disc systems including Quick-Lok compatible accessories. Rated to a maximum of 30,000 RPM, this backing pad suits high-speed die grinders and right-angle tools commonly used in metal fabrication, weld blending, and surface preparation work. The hard backing density provides firm support for aggressive stock removal and consistent disc contact across flat or moderately contoured surfaces. Measuring 2.38 inches in height and 2 inches in width and length, the pad is compact and lightweight at 0.08 pounds.

This backing pad is intended for use in metalworking and light industrial applications where quick-change abrasive discs are the standard. It is well suited for weld seam blending, rust removal, deburring, and general surface conditioning on ferrous and non-ferrous metals. Machinists, fabricators, and maintenance technicians installing or replacing backing pads on pneumatic or electric die grinders will find the Type R quick-change interface provides fast disc swaps without tools, reducing downtime during multi-grit operations.

Installation is performed by threading the backing pad onto a 1/4-20 spindle by hand until snug. Always confirm the tool is powered down and disconnected from the air supply or electrical source before mounting or removing the backing pad. Do not exceed the 30,000 RPM maximum speed rating of the pad or the rated speed of the abrasive disc in use, whichever is lower. Follow ANSI B7.1 and applicable grinding safety standards when operating high-speed abrasive accessories.
