3M 7000120522 Face Plate Sanding Discs 7in 5/8-11

Product Description

The 3M 7000120522 is a plastic face plate designed to back and support sanding discs during grinding and finishing operations. It mounts via a 5/8-11 thread connection to angle grinders and disc sanders, providing a stable substrate that holds abrasive discs securely in place. Rated to a maximum of 7,000 RPM, this face plate is built for use in metalworking, fabrication, and surface preparation applications. The plastic construction keeps overall weight low while delivering sufficient rigidity for standard disc sanding tasks. HVAC, mechanical, and general trade shops rely on this hardware to keep sanding setups running efficiently.

This face plate is suited for use with 7-inch sanding discs on angle grinders and disc sanders equipped with a 5/8-11 spindle thread. It fits into light industrial and professional trade environments where controlled surface finishing is required. Common applications include weld seam blending, rust removal, and surface prep ahead of coating or inspection. Sold as a single unit, it serves as a direct replacement or spare for worn or damaged face plate hardware.

Installation Notes

Installation should be performed by a qualified technician familiar with abrasive tool hardware. Disconnect and de-energize the tool before mounting or removing the face plate. Thread the face plate securely onto the 5/8-11 spindle and verify it is seated before attaching any abrasive disc. Always confirm the assembled tool and disc combination does not exceed the 7,000 RPM maximum rating before operation.
