3M 7000118881 Psa Cloth Sanding Disc 80 Grit 3 Inch

Product Description

The 3M 7000118881 is a pressure-sensitive adhesive (PSA) cloth sanding disc designed for heavy-duty material removal in professional finishing and fabrication environments. Built on an X-weight cloth backing, this 3-inch disc handles aggressive grinding and sanding without tearing or edge breakdown. The aluminum oxide abrasive cuts fast and holds up across a wide range of materials. A resin bond system protects the abrasive layer from heat buildup, extending disc life during sustained use. The PSA backing adheres firmly to compatible backup pads or steel platens and releases cleanly for fast disc changes.

This disc is suited for metalworking, woodworking, and composite surface prep applications where a durable, fast-cutting abrasive is required. At 80 grit, it is appropriate for stock removal, weld blending, and surface leveling before finish grinding. The disc supports both wet and dry sanding applications, making it adaptable to shop environments where coolant or water is used. Machinists, fabricators, and finishing technicians typically use this disc on right-angle grinders or disc sanders fitted with a compatible PSA backup pad or steel platen.
