2 Pieces Diamond Cup Grinder 4 Inch Concrete Turbo Diamond Grinding Cup Wheel 12 Segs Heavy Duty Angle Grinder Wheels for Angle Grinder

For the price you can't beat this. I did some insane work with these, removed mastic glue from floors in many rooms in a house. Used them wet to reduce dust, water didn't bother them. I only used 2, first one wore down a good bit, still has meat on it but the angle grinder bolt was too long to push this flat on the floor at one point. Barely touched the second one. Literally resurfaced the floors of 6 rooms. A lot more work and time but I must have saved $2k versus renting tools. Used the cheapest HF angle grinder, home made ventilation and some n95 masks. Probably spent $45 total. Point is: These work.

I used these 4-inch Diamond Cup Grinder wheels to tackle some seriously uneven concrete at my brother’s house, and wow—they absolutely ground the hell out of the floor flat! The 12-segment turbo design chewed through high spots like butter, making what could’ve been a backbreaking job feel fast and efficient. Attached easily to my angle grinder and held up like champs under heavy use.These wheels are clearly built for tough jobs. No signs of premature wear, no wobbling—just solid, aggressive grinding power from start to finish. Whether you're prepping for flooring, leveling slabs, or just handling some rough patches, this 2-pack gets the job done right. Highly recommended for any DIYer or contractor needing serious performance from their grinding tools.
