• Best For: Floor prep crews on a 7-inch grinder who want a small 3-disc quantity of the coarse 16 grit for a single aggressive pass over thick mastic or epoxy.
• Highlight: Three discs per pack at 16 grit, the coarsest grade in the 7-inch Sawtec range, on a reinforced backing that works without a backer pad.
• Expert Note: Fits a 7/8-inch to 5/8-inch arbor and is rated to 8,500 max RPM, so confirm your grinder speed first; 16 grit leaves a coarse scratch that the next grit step has to refine.
