DEWALT Concrete Grinding Wheel 5-Inch Double Row Diamond Cup DW4777

Description

Product Overview

The DEWALT DW4777 5‑inch concrete grinding wheel is engineered for professional-grade performance on the toughest construction sites. Its double‑row diamond cup design incorporates a high concentration of industrial‑grade diamonds, delivering a 180 grit finish that removes material quickly while maintaining a smooth surface. The wheel measures 5 inches in diameter and fits a 5/8‑11 inch arbor, making it compatible with a wide range of DEWALT angle grinders, including the DCG416B model. Constructed with heat‑treated steel bodies, the wheel resists warping under high‑speed operation, allowing a maximum rotational speed of 12,000 RPM. This combination of robust materials and precise engineering ensures long life, reduced downtime, and consistent results for concrete, masonry, and stone applications.

Usage

Designed for demanding construction environments, this grinding wheel excels in surface preparation, leveling, and removal of cured concrete, mortar, and stone. Whether you are smoothing a freshly poured slab, removing old adhesive, or shaping a concrete countertop, the DW4777 provides the aggressive cutting action needed to achieve a uniform finish. Its medium 180 grit rating balances rapid material removal with a fine enough finish to reduce the need for secondary sanding. The wheel is also suitable for use in renovation projects, where precision and control are essential to avoid damage to surrounding structures. Pair it with a DEWALT angle grinder equipped with a variable speed trigger to match the wheel’s optimal speed range, ensuring safety and efficiency on the job site.
