Cloud-Free Grinding. The DustBuddie is a clear plastic shroud that replaces the factory guard on most grinders and – when attached to an effective vacuum – captures 99 percent of the dust generated by grinding, says the maker. It’s sold in two diameters – 5 inches (for mini grinders) and 7 inches (for full-size grinders) – and comes with a brush skirt and a removable front lip so you can use the grinder for tuck-pointing. Both sizes cost $100. Dustless Technologies, 800/568-3949, dustlesstechnologies.com
