The Scotch-Brite™ clean and strip disc D1 is well-suited for cleaning operations requiring an aggressive cut to remove paint, sealant, rust or other coatings. We gave it a built-in 1/4 in spindle for easy attachment to a die grinder or other portable tool. The Scotch-Brite™ clean and strip disc D1 cleans surfaces quickly and efficiently and is an excellent alternative to wire brushes, without leaving wire splinters behind. Extra coarse grade silicon carbide embedded in resin-covered fibers not only removes rust and coatings quickly, but also leaves a satisfactory finish and may eliminate the need for subsequent finishing steps. The open web construction resists loading for long-lasting usefulness and helps reduce smearing. Silicon carbide is a synthetic mineral that is very sharp and commonly used for low-pressure applications such as paint prep. While it breaks down faster than aluminum oxide, it produces a finer finish. Non-woven technology makes our Scotch-Brite™ industrial abrasives unique. A combination of fiber strands, resin and abrasive mineral forms a thick, open web. The spring-like nature of the fibers responds to contours and effectively removes unwanted burrs, soils and contaminants while maintaining the geometry of the workpiece which in turn reduces rework and boosts productivity. Gaps in the web allow swarf to escape, limiting clogging of the abrasive. Fibers in the web continually break down with use to reveal fresh mineral for exceptional consistency, cut performance and service life. Scotch-Brite™ products may enhance productivity while reducing the need for cleaning chemicals and wire brushes. From aesthetic finishing to weld blending, deburring and more, Scotch-Brite™ abrasives work fast and deliver consistent results, part after part. 3M™ 7000120702, Series: D1, 4 in Diameter Disc, Extra Coarse Grade, Silicon Carbide Abrasive, 8000 RPM Maximum
