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 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 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 Hands down the best!!! This hardware accessory is amazing. Worth every penny you're gonna spent. I grinded down my uneven slap I was tiling with no problem. I thought I was gonna muscle it out, but it was effortless. I personally prefer not to use water, it will be more messy. If it's a confined area you are working on, then just cover things or areas you don't want dust on, then go to town with this bad boy. April 17, 2015
Rated 5.0 out of 5.0 by Does its job It does what I purchased it for, but didn't expectthe debris, good thing to wear protection glasses. The wheels guard only helped a little. I was adjusting periodically and the center screw would loosen. Otherwise it trimmed well for what it was needed. Husband thought it was expensive. April 7, 2015
Rated 5.0 out of 5.0 by Great time-saver! Attached with no problem. Just watch out you don't take too much off. It will eat thru the concrete, mortar or whatever. September 24, 2014
Rated 5.0 out of 5.0 by Does the job!!! Grinds uneven concrete with ease. DON'T UNDERESTIMATE THE MESS IT MAKES! It pulverizes the concrete into billows of dust but works fast and control is manageable. September 16, 2014
Rated 5.0 out of 5.0 by grinder wheel review I bought the wheel to get into smaller spaces that I needed to resurface, this wheel also was good to remove old floor adhesive as well as getting the high spots out of concrete floors March 15, 2015
