Tru-maxx TRU-RS103M Quick-change Type S Disc Backing Pad

Product Description

The TRU-MAXX TRU-RS103M is a Quick-Change Type S disc backing pad designed for use with rotary die grinders and finishing tools. It accepts standard Quick-Lok compatible abrasive discs and features a 1/4-20 male thread shank for secure attachment to compatible grinders. Rated to a maximum of 30,000 RPM, this pad suits high-speed surface prep, deburring, and finishing applications. The medium-density construction provides consistent backing support across the disc face, helping maintain even contact pressure during use. The 1/4-inch shank diameter fits the most common die grinder collet sizes found in metal fabrication and automotive shops.

This backing pad is suited for light to medium material removal and finishing work in metal fabrication, automotive bodywork, aerospace component prep, and general maintenance environments. It is compatible with Quick-Lok type abrasive discs at a 1-inch pad diameter, making it well suited for accessing tight clearances and contoured surfaces where larger pads cannot reach. Machinists, fabricators, and maintenance technicians regularly use pads of this type in production and repair settings.

Installation Notes

Installation is performed by threading the 1/4-20 male shank directly into the die grinder spindle or collet — ensure the grinder is fully powered off and disconnected from the air supply or power source before mounting or removing the pad. Do not exceed the 30,000 RPM maximum rating of the pad or the abrasive disc being used. Verify that the abrasive disc is fully seated and secured on the Quick-Lok interface before operating the tool. Inspect the pad for wear, cracks, or deformation before each use and replace if damage is found.
