Let me start by saying this diamond cup wheel is a beast. I used it to level out uneven concrete slabs on my patio, and it chewed through the material like butter. The double-row segments make aggressive grinding effortless, and the 5mm height gives it serious longevity.

Dust is no joke—this thing creates a storm. I paired it with a shop vac attachment (lifesaver!), but still suited up in a respirator and goggles. Pro tip: Cover nearby furniture if working indoors. That concrete powder gets everywhere.

What shocked me? The value. Compared to the overpriced options at big-box stores, this wheel delivered identical performance to name brands at a fraction of the cost. After feathering out a 1+ inch height difference across 5 feet of concrete, the segments still looked barely worn.

Bonus points for versatility: It handled granite countertop prep beautifully, blending tool marks seamlessly when I hit softer stone patches. The included adapter rings made fitting my Metabo grinder a breeze—no wobble or vibration during heavy use.

One caution: The shallow cup design required me to MacGyver some shims for optimal dust shroud alignment during thinset removal. But for raw grinding power? This wheel’s my project MVP—especially after surviving 8+ hours of sidewalk paint stripping without dulling.
