Tru-maxx TRU-RS303S Disc Backing Pad Quick-change Type S 3 Inch

Product Description

The TRU-MAXX TRU-RS303S is a 3-inch soft-density disc backing pad designed for quick-change Type S abrasive disc systems. It accepts a 1/4-20 male thread shank and is rated to a maximum of 20,000 RPM, making it suitable for high-speed grinding, blending, and finishing operations. The soft density construction allows the pad to conform to contoured or irregular surfaces, improving contact and cut consistency. This pad is compatible with Quick-Lok quick-change disc systems and is sized for use with standard 3-inch abrasive discs. It is a compact, lightweight component at 0.14 pounds and is used across metal fabrication, maintenance, and surface preparation work.

This backing pad is intended for use with angle grinders, die grinders, and other rotary tools equipped with a 1/4-inch shank arbor. The quick-change Type S design allows abrasive discs to be swapped rapidly without additional tools, reducing downtime in production or field service environments. Typical applications include weld blending, rust removal, paint stripping, and deburring on metal surfaces. The pad suits both shop and jobsite use where repeated disc changes are common and speed of turnaround matters.

Installation Notes

Installation is performed by threading the 1/4-20 male shank into a compatible grinder or die grinder arbor and securing it firmly before attaching any abrasive disc. Always confirm the tool's rated RPM meets or exceeds the maximum RPM of the backing pad before operation. Power down and disconnect the tool from its power source before mounting or removing the pad or any attached disc. Inspect the pad for wear, delamination, or damage before each use and replace if any degradation is found.
