3M 7100199445 Scotch-brite Hs Blend Finish Disc 8 in Ao Medium

Product Description

The 3M 7100199445 is a Scotch-Brite HS Blend and Finish Disc designed for aggressive surface conditioning on metal workpieces. Built with the toughest web material in the Scotch-Brite surface conditioning disc lineup, this 8-inch diameter disc runs at up to 3000 RPM and accepts a 1/2-inch arbor. Aluminum oxide medium-grade mineral provides efficient cutting action for weld burn removal, deburring, blending, finishing, and rust removal. The open-web construction resists loading, extending disc life under demanding conditions.

This disc is suited for metal fabrication and finishing applications in industrial, manufacturing, and trade environments. It performs well on steel, stainless, and other ferrous surfaces where a consistent satin finish is required after welding, grinding, or machining. The springy nonwoven fibers conform to irregular and contoured surfaces, delivering uniform results across flat and curved workpieces. Metalworkers, fabricators, and maintenance technicians commonly use this disc for both production and maintenance tasks.
