Professional 7-Inch Double Row Diamond Cup Grinding Wheel with 5/8-11 Threaded Spindle Arbor
The DeWALT DW4773 is an industrial-grade 7-inch double row diamond cup grinding wheel engineered to execute high-speed surface smoothing, concrete leveling, and masonry coating removal operations. Driven by a high-density diamond abrasive concentration embedded in a 0.51-inch segment height layout, this heavy-duty wheel operates safely at a maximum rotational speed of 8,600 RPM. The heat-treated structural steel core chassis features large dual-row peripheral segments built with a 0.40-inch diamond depth to ensure high stock removal rates while checking wheel wobble on heavy-duty commercial side grinders and right angle grinders.
Best Used For:
- Commercial Floor Leveling: Flattening uneven joint ridges, rough aggregate bumps, and structural high spots on cured concrete foundation pads cleanly.
- Epoxy Coating Stripping: Grinding away stubborn mastic materials, old waterproofing membranes, and thick industrial floor sealers before layout floor refinishing.
- Masonry Wall Smoothing: Dressing rough vertical brick masonry block boundaries or poured wall seams during structural building configurations.
Key Performance & Safety Features
- High Diamond Concentration: Premium industrial diamond embedding optimization accelerates hard aggregate shaving and prolongs service longevity.
- Dual Row Peripheral Alignment: Parallel segment placement grids balance lateral grinding stability to deliver smoother surface leveling actions.
- Heat-Treated Steel Platform: Rigid structural steel core matrix base plate withstands immense centrifugal mechanical loads while checking deformation profiles.
- 0.40 Inch Diamond Depth: Extra deep concentration zone ensures continuous cutting exposures to preserve tool performance over extensive area runtimes.
- Direct 5/8-11 Threaded Arbor: Integrated female thread pattern permits spin-on mounting mechanics, eliminating loose washer setups.

Pro-Tip: When smoothing broad concrete floor sections, maintain a slight 5-degree tilt relative to the work slab surface and utilize the tool weight to guide the grinder across target layout tracks. Forcing down the disc shifts segment paths off-balance, inducing circular groove marring risks and accelerating matrix temperature fatigue.
