3M 7010364096 Flexible Grinding Wheel Backup Pad

Product Description

The 3M 7010364096 is a clear plastic backup pad designed to support flexible grinding wheels during angle grinder operations. The pad provides a rigid backing surface that stabilizes the wheel, improving contact consistency and helping the abrasive perform evenly across the workpiece. It measures 3.375 inches in diameter with a 0.875-inch center hole, making it a direct fit for standard 4.5-inch flexible grinding wheels with a 7/8-inch arbor hole. Weighing just 0.04 pounds, it adds negligible mass to the grinder assembly. Fabricators, welders, and metalworkers who use flexible grinding wheels for blending and finishing will find this pad useful as a replacement or spare backup component.

This backup pad is suited for use in metal fabrication, structural steel work, and weld finishing applications where flexible grinding wheels are mounted on angle grinders. It is appropriate for both shop and field use. The pad supports the wheel body during contact with flat or contoured surfaces, reducing flex-induced chatter and uneven wear. It is sold individually and is intended for professional tradespeople working with 4.5-inch flexible abrasive wheels on standard 7/8-inch arbor grinders.
