3M 7000118886 Psa Cloth Disc 348D 20 Inch 50 Grit Ao

Product Description

The 3M 7000118886 is a pressure-sensitive adhesive (PSA) cloth sanding disc in the 348D series, designed for heavy-duty material removal in industrial and trade applications. The disc measures 20 inches in diameter and is loaded with 50-grit aluminum oxide abrasive bonded with a resin system that resists heat buildup during aggressive cutting. An X-weight cloth backing gives the disc the rigidity needed to handle high-pressure stock removal without tearing or edge breakdown. The PSA backing adheres firmly to a backup pad or steel platen and releases cleanly for fast disc changes.

This disc is suited for large-format surface grinding, blending, and finishing tasks on metal, wood, composites, and other hard surfaces. The 50-grit cut rate makes it appropriate for initial stock removal and heavy scratch leveling rather than fine finishing. It supports both wet and dry sanding environments, giving operators flexibility across different shop and jobsite conditions. Minimum order quantity is 10 discs per purchase.

Compatibility

Designed for use with backup pads and steel platens that accept 20-inch PSA-mount sanding discs on large disc grinders and finishing machines.

Installation Notes

Mounting and disc changes should be performed with the machine powered off and unplugged or locked out per applicable safety procedures. Clean the backup pad or platen surface before applying the PSA disc to ensure full adhesion and even pressure distribution. Inspect the disc for tears or edge damage before each use and replace immediately if defects are found. Disc installation and grinding operations should follow applicable ANSI and OSHA standards for abrasive wheel safety.
