3M 7100198947 Psa Cloth Sanding Disc 40 Grit 6 Inch

Product Description

The 3M 7100198947 is a PSA cloth sanding disc designed for heavy-duty material removal on a wide range of surfaces. The disc uses an aluminum oxide abrasive at 40 grit for aggressive cutting action and long service life. A pressure-sensitive adhesive backing bonds firmly to a backup pad or steel platen, allowing fast disc changes without adhesive residue. An X-weight cloth backing resists tearing and edge wear under demanding conditions. Resin bond construction protects the abrasive layer from heat buildup, extending disc life during sustained use. The disc is rated for both wet and dry sanding applications.

This disc is suited for metal fabrication, weld grinding, rust removal, and surface preparation tasks in industrial, manufacturing, and trades environments. The 40-grit cut rate makes it appropriate for stock removal and aggressive blending rather than finish work. Licensed trades professionals and production floor operators working with angle grinders and disc sanders will find this disc a direct fit for high-throughput applications where fast pad swaps reduce downtime.

Installation Notes

Ensure the backup pad or steel platen surface is clean and free of adhesive residue before applying a new disc. Power down and disconnect the grinder or disc sander before changing discs. Press the disc firmly onto the pad from center outward to eliminate air pockets and ensure full adhesive contact. Discs should be inspected for damage before each use and discarded if tears or delamination are present.
