Diamond Cup Wheels & Grinding Cups for Stone & Concrete | Pro Tool Haus

Diamond cup wheels and grinding cups are the primary stock removal tools in stone and concrete grinding — they aggressively remove material, flatten surfaces, and prepare stone for the polishing sequence. Mounted on angle grinders, they're used for lippage removal on installed tile floors, surface leveling on stone countertops, and coarse grinding prior to polishing. 

Pro Tool Haus carries single-row cup wheels for general grinding and edge work, double-row cup wheels for faster material removal on flat surfaces, and turbo cup wheels for aggressive stock removal on hard granite and concrete. All in standard 4" and 5" diameter for angle grinder compatibility. 

Single row cups are better suited for detail and edge work; double row for flat surface grinding; turbo cups for maximum stock removal where surface quality is secondary. See Grinding Coring Stock Removal for the full range of aggressive stock removal tooling.
