3M 7000120989 Scotch-brite Abrasive Disc 8 Inch Ao

Product Description

The 3M 7000120989 is a Scotch-Brite High Strength non-woven abrasive disc designed for general-purpose surface conditioning in metalworking applications. Built on a durable, open-web construction, the disc resists loading and runs cool, allowing the aluminum oxide abrasive to cut at a consistent rate from first use through the end of the disc life. The 8-inch diameter disc mounts on a 0.5-inch arbor and is suited for deburring, denibing, defuzzing, cleaning, and achieving satin finishes on metal surfaces. Fabricators, machinists, and maintenance technicians are the primary users of this disc type.

This disc is applied across a wide range of metalworking tasks in both production shop and maintenance environments. Its conformable, non-woven structure follows irregular contours and surface profiles, making it well suited for finishing weld seams, removing burrs from cut edges, and preparing surfaces before coating or inspection. The open-web design prevents swarf and debris from embedding into the disc face, which extends working life and maintains consistent cut quality throughout use. Multiple discs can be stacked on the same arbor to increase working thickness or cover larger surface areas in a single pass.

Key Features

• Open-web, non-woven construction resists loading and runs cool for consistent cut rate throughout disc life
• Aluminum oxide abrasive mineral handles deburring, denibing, defuzzing, and cleaning on a wide variety of metals
• Conformable disc body follows contours and surface irregularities for even finish results
• Wear-resistant edge supports long disc life and consistent finish quality
• Discs can be stacked to increase working thickness or cover larger surface areas
• Tough non-woven material supports heavy-duty use in production and maintenance settings

Compatibility

Designed for use on right-angle grinders and disc sanders equipped with a 0.5-inch arbor accepting an 8-inch non-woven abrasive disc.

Installation Notes

Installation is performed by machinists or fabricators following standard shop safety procedures. Power down and lock out the grinder or disc sander before mounting or removing the disc. Verify that the tool spindle speed rating meets or exceeds the maximum rated speed of the disc before operation. Inspect the disc for damage before each use and do not operate a disc that shows tears, delamination, or unusual wear.
