3M 7100123285 Flexible Grinding Wheel Backup Pad

Product Description

The 3M 7100123285 is a clear plastic backup pad designed to support flexible grinding wheels during surface grinding and finishing operations. The pad provides a rigid foundation that keeps the grinding wheel properly seated and stable under load, reducing deflection and helping maintain consistent contact across the work surface. It is sized to fit 7-inch grinding wheels with a 0.875-inch center hole and is sold individually. This part is typically installed by metalworking professionals, fabricators, and maintenance trades using angle grinders or disc grinders on ferrous and non-ferrous materials.

This backup pad is suited for use in light industrial, fabrication shop, and general maintenance environments where flexible grinding wheels require a support plate. The clear plastic construction allows the operator to visually confirm wheel seating before and during use. It is intended for applications where a standard rigid backing is needed behind a 7-inch flexible grinding wheel with a 0.875-inch arbor hole.
