If you’re in the business of prepping concrete and masonry, the is one of those accessories you’re gonna notice on your grinder and not forget. This isn’t a flimsy disc that melts away after a couple of uses — it’s built with a double‑row diamond layout that goes after material hard and fast. In practice, that means you’ll cut through uneven patches, ridges, and rough spots a heck of a lot quicker than with a standard wheel.

The tool leans on premium diamond abrasive segments set into a heat‑treated steel body — and you can feel the difference. On concrete, stone, or brick, it bites deep but keeps you in control, and the 115 mm size means it fits all the common angle grinders most tradespeople already own. If you’re serious about surface prep, this wheel deserves a spot in your kit.

Key Features:

• Double Row Diamond Segments - Grinds aggressively and keeps cut rates up even on tough masonry.
• 115 mm Diameter - Matches standard 4½″ grinders so you don’t have to buy special gear.
• Heat‑Treated Steel Body - Adds durability so the wheel doesn’t twist or wobble under load.
• High Diamond Concentration - Stays sharper longer and means fewer wheel changes on the job.
• Universal Bore Fit - Works with the typical 22.2 mm arbor found on most grinders.

Applications

The work this wheel is made for is pretty straightforward: concrete, stone, and masonry surface prep. That means things like taking down high spots in a slab, cleaning up old weld marks, smoothing rough edges on block walls, or getting a patch ready for fresh concrete — the diamond cup grinding wheel makes those chores way less of a grind. It’s not a polishing disc, but for material removal and leveling, it delivers exactly what you’re after.

Why Choose This Model

Here’s the thing — not all grinding wheels are built equal. This DeWalt wheel stands out because of that double‑row segment setup and high diamond load. What really matters out in the field is consistency and life, and you get both: faster stock removal and fewer stops to swap wheels. And that matters a lot on a job site where every minute counts and wheel changes add up. Plus, the fitment’s right in the sweet spot for most grinders you’ll use daily.

Technical Specifications Explained

• Diameter – 115 mm - Fits common angle grinders without adapters.
• Bore Size – 22.2 mm - Standard arbor size keeps it compatible with most grinders.
• Double Row Design - Two lines of cutting diamonds mean faster grind and smoother progress.
• Diamond Grit - Hard abrasive that chews through concrete and masonry without glazing over instantly.
• Steel Wheel Body - Gives the wheel strength and resists deformation under pressure.

Who Should Buy This

If you’re knee‑deep in concrete or masonry work — whether you’re a contractor, a flooring pro, or a serious DIYer — this diamond cup grinding wheel is a tool‑belt must. You’ll notice the difference right away when you need to strip, level, or prep surfaces without faffing around with slow cutting discs.

But if you only grind wood or metal occasionally, this isn’t your everyday wheel — you’re better off with something made for that material. For concrete and stone though? This one’s solid.
