The DeWalt DW4772T Double Row Diamond Cup Wheel is a grinding accessory built for serious surface work — it’s made to thrash concrete and other hard materials without whining or slowing you down. Built with two rows of gritty diamond segments, it pulls material off fast and keeps you moving when you’ve got slabs, edges and profiles to clean up.

If you’re sick of wheels that bog down or wear out after a handful of jobs, this double row diamond cup wheel is a step up from basic wheels — it lasts longer and grinds more consistently thanks to its heavy‑duty design and high diamond concentration.

Key Features:

• Double Row Diamond Segments - Two abrasive lines chew through concrete and masonry quicker than single row wheels.
• High Diamond Concentration - Grit packed in tight for longer life and aggressive material removal.
• Heat‑Treated Steel Bodies - Keeps the segments solid under pounding, so the wheel doesn’t peel apart mid‑job.
• Turbo Fan Construction - Spins dust and debris away from your work zone — that matters on dusty jobs.
• Standard Arbor Fit - Works on most angle grinders with a 22.2 mm bore, so you don’t need special adapters.

Applications

In practice, this diamond cup wheel is your go‑to for grinding and profiling concrete, brick, block and other masonry — it’ll open up rough spots, feather edges, and take down high spots on slabs without bogging the grinder.

Why Choose This Model

Here’s the thing — not all cup wheels are created equal. This model’s double row setup and solid steel segment bodies make it better for heavy work and repeated use than cheap single row wheels, so you spend less time swapping wheels and more time grinding.
