• Best For: Angle-grinder users doing edge and corner work who need a coarse step that is slightly less aggressive than 8 grit on stucco, paint or urethane.
• Highlight: 16 grit in a 4-1/2-inch size, the second-coarsest grade in the 4-1/2-inch range after 8 grit.
• Expert Note: Uses the same 7/8-inch to 5/8-inch arbor as the larger discs, so keep to the 8,500 max RPM rating when running it on a small angle grinder.
