Rated 4.7 out of 5 by 33 reviewers.
Rated 5.0 out of 5.0 by Great product for grinding concrete Works great for grinding concrete. Works well dry or wet to grind down high spots on concrete floor or sidewalk. Using wet keeps down dust and, I assume, extends the life. Should work even better on masonary. December 27, 2012
Rated 5.0 out of 5.0 by Makes quick work of grinding concrete Used this to even cracks in concrete Filled using patch compound and used again to level. This does create a lot of dust so wetting the concrete does help. Keep moving to avoid creating holes September 4, 2014
Rated 5.0 out of 5.0 by Worked great I used this wheel for the first grind of my concrete counter tops. I used a disposable pad for the first top and it took forever. So a ran to HomeDepot and picked up this wheel and it sped up my process 100 fold. I blazed through the rest of the pieces. October 28, 2014
Rated 4.0 out of 5.0 by dimond hand grinder for block / concete HomeDepot carried another brand which was better quality. It no longer carries that. This one does not cut as aggressive, and cannot get into finer cut areas due to bulk but on flip side is more durable. Price of this vs other brand offering is 1/2 and from my use, it is holding up as good as the more expensive ones. July 21, 2015
Rated 5.0 out of 5.0 by A great grinding disk. I am using it ti grin off ceramic glaze that ran. I had tried other grinders and they were very slow. This one works great and fast. June 23, 2015
Rated 5.0 out of 5.0 by Works Great Did exactly what I needed to accomplish take of the top layer of concrete so I could get a good bond with the epoxy that I am going to apply. June 22, 2015
Rated 5.0 out of 5.0 by Grinds like a champ This wheel really tears into concrete. I had to take about a half inch off a high area in a slab (approx 3'x3') to prep for a laminate floor. I couldn't believe how well it cut into the concrete. The wheel still looks brand new. It fits on my Ryobi grinder. As others have said, there is an awful lot of dust. I recommend keeping the area wet. Use the shroud, goggles and a mask. June 11, 2015
Rated 5.0 out of 5.0 by Another Quality Ridgid Tool! Not cheap, but for grinding concrete you can't beat it! So far I've only used it to smooth and level a concrete sill for a new pre-hung door, and it's already paid for itself! June 14, 2015
