Scotch-Brite Light Grinding and Blending Discs use ceramic aluminum oxide, a blended ceramic mineral engineered to fracture frequently and surpass aluminum oxide abrasives in both cut-rate and durability. Available in both Heavy Duty (HD) and Super Duty (SD) coarse depending on your finish and aggressiveness needs this proprietary ceramic blend is built to cut fast and handle intense stress applications. Thanks to these performance benefits, Super Duty (SD) discs are able to grind and blend in a single step where a 3 mil or greater paint thickness is being applied, while Heavy Duty (HD) discs are made for applications with less than 3 mil making Scotch-Brite Light Grinding and Blending Discs a high-performance, 'all-in-one' solution.
