3M 7000045285 Roloc Disc Backup Pad 3 in 1/4-20

Product Description

The 3M 7000045285 is an extra-hard backup pad engineered to support 3M Roloc 3-inch diameter abrasive discs in grinding, blending, and finishing applications. The pad features a 1/4-20 INT thread, allowing direct mounting to tools with a 1/4-20 EXT threaded shaft or attachment via a Roloc shank for use with collet chuck tools. Weighing just 0.2 pounds, this lightweight pad minimizes operator fatigue during extended use. It is installed by metalworking and fabrication professionals who need consistent disc backing rigidity to maintain surface contact and achieve repeatable finish results.

This backup pad is suited for use in metal fabrication shops, automotive body work, and general industrial finishing environments. It is compatible with handheld angle grinders, die grinders, and other rotary tools equipped with a 1/4-20 EXT threaded shaft or a compatible Roloc shank adapter. The extra-hard durometer rating provides firm support across the full face of the 3-inch abrasive disc, making it appropriate for flat and low-contour surface work where disc flex is not desired.

Installation Notes

Installation is performed by metalworking technicians or fabricators using standard hand tools. Always power down and disconnect the tool from its power source before mounting or removing the backup pad. Thread the pad securely onto the tool shaft or shank before attaching the abrasive disc. Inspect the pad for wear or damage before each use and replace if the backing surface is compromised.
