3M 7010326512 Psa Cloth Sanding Disc 15 Inch 40 Grit

Product Description

The 3M 7010326512 is a 15-inch PSA cloth sanding disc designed for heavy-duty material removal on flat or contoured surfaces. The pressure-sensitive adhesive backing mounts directly to a backup pad or steel platen, allowing fast disc changes with clean removal and no adhesive residue transfer. The disc uses aluminum oxide abrasive at 40 grit for aggressive stock removal, and a resin bond system protects the abrasive layer from heat buildup to extend working life. X-weight cloth backing resists tearing and edge wear under sustained pressure. Suitable for both wet and dry sanding operations, this disc is a reliable choice for production grinding and finishing environments.

This disc is used in industrial and manufacturing settings where large-diameter flat grinding or surface conditioning is required. Typical applications include wide-belt platen backup operations, large panel stock removal, weld blending, and surface prep on metal, wood, or composite substrates. The 40-grit cut rate makes it well suited to initial stock removal passes before progressing to finer abrasives. Licensed tradespeople and production floor operators working with large stationary or portable disc machines will find this disc fits standard PSA-style platen systems.

Installation Notes

Installation is performed by production operators or maintenance technicians familiar with disc grinding equipment. Power down and lock out the machine before removing the spent disc and mounting a new one. Press the disc firmly across the entire face of the platen to ensure full adhesive contact before resuming operation. Inspect the backup pad or platen surface for debris or damage that could cause uneven disc seating prior to each disc change.
