3M 7000118888 Psa Cloth Disc 20 Inch 36 Grit Ao

Product Description

The 3M 7000118888 is a PSA cloth sanding disc designed for heavy-duty material removal in industrial and fabrication environments. The pressure-sensitive adhesive backing mounts directly to a backup pad or steel platen, allowing fast disc changes without tools. The disc uses an aluminum oxide abrasive grain bonded with a resin system that resists heat buildup, extending usable disc life. At 36 grit, it is suited for aggressive stock removal on metal, wood, and composite surfaces. A durable X-weight cloth backing resists tearing and edge wear under sustained cutting pressure. Licensed trades and fabrication shops are the primary installers and users of this disc.

This disc is used in fixed and portable disc grinding applications in metal fabrication, woodworking, and general industrial finishing. The 20-inch diameter fits large-format disc sanders and platen grinders where high-volume material removal is required. The disc supports both wet and dry sanding operations, making it adaptable to shop environments with or without coolant or water. Minimum order quantity is 10 discs per unit of measure.
