3M 7100074475 Hook Loop Disc 120 Grit 1 Inch Diamond

Product Description

The 3M 7100074475 is a 1-inch hook-and-loop abrasive disc designed for precision surface finishing on hard materials. Part of the 3M 6002J series, it features a diamond abrasive coating bonded to a flexible cloth backing, making it well-suited for grinding and finishing operations where consistent material removal and surface quality matter. At 120 grit (fine grade, 125 micron), this disc delivers controlled stock removal without aggressive cutting, which is critical when working close to a finished dimension. The hook-and-loop attachment system allows fast disc changes without tools, reducing downtime during repetitive finishing tasks. It weighs 0.05 pounds and ships individually.

This disc is intended for use with compatible 1-inch hook-and-loop backing pads on die grinders, right-angle grinders, or detail finishing tools. It is commonly used in metalworking, stoneworking, ceramic finishing, and composite surface preparation where diamond abrasive is required. The flexible cloth backing conforms to contoured and flat surfaces alike. Typical users include machinists, fabricators, tile and stone installers, and maintenance technicians performing precision finishing work on hard or brittle materials.

Compatibility

Designed for use with 1-inch hook-and-loop backing pads on die grinders and detail finishing tools that accept discs in the 3M 6002J series format.

Installation Notes

Ensure the backing pad on the tool is clean and free of debris before attaching the disc to maintain a secure hook-and-loop bond. Confirm the tool spindle speed rating is appropriate for small-diameter abrasive discs before operation. Wear appropriate eye protection and follow all applicable safety guidelines when operating grinding and finishing equipment. Inspect the disc for damage before each use and replace if the abrasive layer shows signs of loading or delamination.
