Tru-maxx TRU-RR304S 3 Inch Quick-change Disc Backing Pad

Product Description

The TRU-MAXX TRU-RR304S is a Quick-Change Type R disc backing pad designed for use with rotary tools and angle grinders in grinding, sanding, and surface preparation applications. The pad measures 3 inches in diameter and accepts Quick-Lok quick-change abrasive discs, allowing fast disc swaps without tools. It features a 1/4-20 female thread mount and a 1/4-inch shank diameter, with a soft density construction that provides flex and conform to irregular or contoured work surfaces. Rated to 20,000 RPM, this backing pad is suited for metalworking, fabrication, and finishing tasks performed by machinists, pipefitters, welders, and general maintenance trades.

This backing pad is intended for use with Quick-Lok compatible quick-change abrasive discs in both shop and field environments. Typical applications include weld blending, rust removal, deburring, and surface conditioning on metal components. The soft density backing allows the disc to follow curved or uneven surfaces more effectively than rigid alternatives, making it a practical choice for contoured workpieces and tight-access areas common in fabrication and maintenance work.

Installation Notes

Install this backing pad by threading it onto the tool spindle hand-tight before mounting an abrasive disc. Always verify the tool spindle speed does not exceed the 20,000 RPM maximum rating of this pad before operation. Disconnect the tool from its power source before attaching or removing the backing pad or any abrasive disc. Inspect the pad for wear, cracks, or deformation before each use and replace if damaged.
