DEWALT DW4777 5-Inch Double Row Diamond Cup Wheel Angle Grinders High Concentration Abrasive Grinding Disc Aggressive Concrete and Masonry Removal

Achieve Flawless Surfaces with the DEWALT Double Row Diamond Cup Grinding Wheel

The DEWALT DW4777 5-Inch Double Row Diamond Cup Wheel is engineered for the most demanding surface preparation tasks. Featuring a high concentration of industrial-grade diamonds, this grinding disc provides exceptionally aggressive material removal and an extended service life compared to standard abrasive wheels. Whether you are leveling uneven concrete floors, removing heavy coatings, or smoothing out masonry joints, the double-row segment design ensures maximum contact with the surface for a faster, more efficient workflow. It is the go-to choice for flooring contractors and masonry professionals who require a reliable tool for bulk material thinning and surface finishing.

Durability is at the core of the DW4777's design. Built with heat-treated steel bodies, these cup wheels are designed to withstand the intense heat and friction generated during high-speed grinding with an angle grinder. The large grinding segments are strategically placed to provide a consistent scratch pattern and prevent premature wear, while the precision-balanced body reduces vibration to minimize user fatigue. This high-performance diamond wheel delivers professional-grade results on cured concrete, stone, and brick, making it an essential accessory for any heavy-duty construction or renovation project.

Pro-Tip: Always use a dust shroud and a vacuum system when grinding concrete with a diamond cup wheel. Not only does this protect your health from silica dust, but it also keeps the work surface clear, allowing the diamond segments to bite into the material more effectively without "floating" on debris.
