• Highlight: The MK Diamond Sawtec 4-1/2-inch 8-grit silicon-carbide discs rip aggressively into mastic, epoxy, paint and carpet glue without loading up, and the reinforced plastic backing eliminates the need for a separate backer pad on small angle grinders.
• Best For: Floor-prep crews, mastic and glue removal on small footprints, edges and corners that a walk-behind grinder cannot reach, restoration shops surfacing tile, stone and concrete.
• Expert Note: The 8-grit Sawtec is the coarsest of the four-disc Sawtec lineup; on a 4-1/2-inch grinder it strips thick mastic or epoxy in a single pass, then step up through 16 and 24 grit for a finer profile before sealing or coating.
