3M 7000121045 Scotch-brite Cut Polish Disc 5 Inch Ao

Product Description

The 3M 7000121045 is a non-woven cut and polish disc designed to produce satin or high-luster surface finishes on a variety of metals. Built on an open-web construction, it resists loading and extends service life compared to conventional abrasive discs. Aluminum oxide mineral provides an aggressive cut rate while generating low heat, allowing extended contact with the workpiece without distortion or discoloration. At 5 inches in diameter with a 1/4-inch arbor, it mounts to bench motors or straight-shaft tools. Metalworkers and fabricators use this disc for blending, finishing, cleaning, and light deburring applications.

This disc is suited for both production and maintenance environments where consistent surface finish quality is required. It performs on ferrous and non-ferrous metals, making it applicable across sheet metal fabrication, welding cleanup, and general surface conditioning. The 1/4-inch arbor mount makes it compatible with straight-shaft die grinders and bench-mounted spindle tools commonly found in fabrication shops and maintenance facilities. Its non-woven structure allows the disc to conform slightly to contoured surfaces, which is useful when blending welds or smoothing irregular edges.

Installation Notes

Mounting and disc changes should be performed with the tool fully powered down and unplugged. Verify the tool spindle speed does not exceed the rated maximum speed of the disc before operation. Wear appropriate PPE including eye protection and gloves when handling and operating abrasive discs. Inspect the disc for damage before each use and do not use a disc that shows tears, fraying, or delamination of the web material.
