Scotch-Brite 61500068319 C5-ZS Cut and Polish Disc, 3 in Dia x 1-1/4 in W, 1/4 in Straight Shaft, Aluminum Oxide Medium, 10,000 RPM

General purpose surface-conditioning discs for use on all metals have a nonwoven aluminum oxide abrasive to remove burrs and smooth surface imperfections. Surface-conditioning abrasives made of nonwoven nylon conform to irregular surfaces and remove surface imperfections, mill scale, and surface rust to create a smooth surface ready for finishing. Aluminum oxide is a strong, sharp, and durable abrasive that penetrates the work surface and withstands heat and high speeds. Example metals include mild and carbon steel, cast iron, cobalt, titanium, and chrome.
