3M 7010361777 Psa Cloth Sanding Disc 8 Inch 40 Grit

Product Description

The 3M 7010361777 is a pressure-sensitive adhesive (PSA) cloth sanding disc engineered for heavy-duty material removal in professional grinding and finishing operations. The disc uses an aluminum oxide abrasive at 40 grit for aggressive stock removal across a wide range of surfaces. A resin bond system protects the abrasive from heat buildup, extending disc life under sustained use. The PSA backing adheres firmly to compatible backup pads and steel platens, then releases cleanly for fast changeovers. Fabricators, metalworkers, and finishing technicians working with angle grinders or disc sanders are the primary installers of this disc.

This disc is suited for both wet and dry sanding applications on metal, wood, composites, and similar materials. The X-weight cloth backing resists tearing and edge wear under aggressive pressure, making it appropriate for production-level material removal tasks in shop and field environments. Its 8-inch diameter fits standard backup pads designed for that disc size. The 40-grit cut makes it most effective as a first-pass or rough-stock-removal disc before stepping up to finer grits.

Installation Notes

Disc installation and replacement should be performed with the grinder or sander powered off and unplugged or locked out per standard shop safety practice. Clean the backup pad or platen surface before applying the PSA disc to ensure full adhesion. Verify the disc diameter and PSA mount type match the backup pad before use. Worn or damaged discs should be removed and replaced promptly to avoid surface defects or disc failure during operation.
