• Highlight: MK Diamond's MK-304SG-2 double-row diamond cup wheel strips thin-set, mastic, paint, and floor adhesives faster than single-row designs — paired with a 4" angle grinder it knocks out small areas without renting a walk-behind grinder.
• Best For: Tile contractors, flooring installers, and concrete prep crews removing thin-set ridges, glue residue, and paint from concrete before new flooring.
• Expert Note: The 4" (102mm) cup runs on 4-1/2" angle grinders at ~10,000-12,000 RPM with the 7/8"-5/8" reducer bushing; double-row segments give faster stock removal but require lighter pressure to extend bond life.
