3M 7000118900 Psa Cloth Disc 348D 24 Inch 50 Grit Ao

Product Description

The 3M 7000118900 is a pressure-sensitive adhesive (PSA) cloth sanding disc in the 348D series, designed for heavy-duty material removal on large flat surfaces. At 24 inches in diameter with a 50-grit aluminum oxide abrasive, this disc delivers fast, aggressive cutting action suited to high-production sanding operations. A resin bond locks the abrasive to the backing and shields the disc from heat buildup during extended use. Licensed tradespeople and industrial finishers working with large platens or backup pads will find the PSA mount system straightforward to apply and remove.

This disc is built for wide-surface applications such as panel sanding, furniture manufacturing, flooring prep, and industrial fabrication. The 24-inch format fits large stationary disc sanders equipped with a backup pad or steel platen. The disc supports both wet and dry sanding conditions, making it adaptable to a range of shop environments and substrate types. Minimum order quantity is 10 discs per purchase.

Key Features

• PSA backing adheres firmly to backup pads and steel platens for quick mounting and clean, fast removal
• X-weight cloth backing resists tearing and edge wear under aggressive stock-removal conditions
• 50-grit aluminum oxide abrasive provides fast cutting with extended service life across a wide range of surfaces
• Resin bond construction reduces heat damage and extends disc life in high-friction applications
• Rated for both wet and dry sanding applications

Compatibility

Designed for use with large stationary disc sanders, backup pads, and steel platens that accept a 24-inch PSA-mount abrasive disc.

Installation Notes

Installation is performed by trade finishers and industrial abrasive equipment operators. Before mounting, ensure the backup pad or steel platen surface is clean and free of debris to allow full PSA contact. Power down and lock out the sanding machine before disc replacement. Remove the disc by peeling cleanly from the platen to avoid adhesive residue buildup.
