3M 7100141898 Scotch-brite Cut Polish Disc 8 Inch Ao

Product Description

The 3M 7100141898 is a Scotch-Brite Cut and Polish Disc designed to produce satin or high-luster finishes on a variety of metal surfaces. Built on a durable open-web, non-woven construction, this 8-inch disc uses aluminum oxide mineral to deliver an aggressive cut while maintaining a polished surface. The open-web design resists loading, which extends service life compared to conventional abrasive discs. It is well-suited for metalworking professionals who need a single tool that handles both aggressive material removal and finish work in one step.

This disc is used in metal fabrication, maintenance, and finishing applications across both light industrial and shop environments. The 1/2-inch arbor configuration allows it to mount on a bench motor or straight-shaft tool, making it adaptable to common workshop setups. It performs well on ferrous and non-ferrous metals, handling tasks such as blending weld seams, light deburring, and surface conditioning where a consistent finish is required.
