DEWALT Diamond Cup Grinding Wheel DW4775 7 Inch Double Row Saw Accessory (5/8-11 Threaded Arbor 8600 RPM Concrete Masonry Surface Preparation)

Aggressive Double Row Diamond Core for High Production Slab Leveling

The DEWALT DW4775 is a 7-inch double row segmented diamond cup grinding wheel engineered to execute rapid material removal and surface preparation on concrete and masonry. Operating at rotational speeds up to 8,600 RPM, this premium accessory features a 5/8-inch-11 threaded arbor for direct attachment to high-powered industrial angle grinders. The extended-performance diamond matrix incorporates large heat-treated steel segments that withstand intense thermal friction during heavy-duty dry grinding, leveling, and coating removal tasks.

Best Used For:

• Concrete Floor Leveling: Grinding down high spots, rough seams, and structural unevenness on large poured concrete slabs.
• Industrial Coating Removal: Stripping away thick epoxy layers, stubborn thinset adhesives, master sealants, and old paint matrices.
• Masonry Surface Restoration: Smoothing out irregular brickwork, rough cinder blocks, and concrete foundation walls cleanly.

Key Performance & Safety Features

• Extended Performance Matrix: Advanced industrial diamond bond formulation outlasts conventional abrasive discs to maximize accessory longevity.
• Double Row Segment Configuration: Multi-segment layout delivers a highly aggressive bite and smoother surface flattening than single-rim options.
• Heat-Treated Steel Base: Robust structural steel backing plates resist thermal expansion and distortion under high-torque mechanical loads.
• High Diamond Concentration: Uniformly distributed diamond grid layout yields a faster, cleaner cut rate for commercial surface prep.
• Integrated Threaded Hub: Internal 5/8-11 thread mounts directly onto grinder spindles for stable, low-vibration rotational balance.

Technical Specifications

Pro-Tip: When profiling concrete dry, keep the cup wheel flat against the slab surface and move in sweeping, circular motions; let the tool speed do the work rather than applying excessive downward body pressure, which avoids uneven groove cutting and premature segment friction glazing.
