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 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 2.0 out of 5.0 Not thebest I purchased this to grind paint off my basement floor. I managed to clean up about 3 square feet before wearing the coating off the wheel. I was grinding it at a slow speed and wet. Let's just say I was disappointed. I expected to be able to clean up a significantly larger area. May 2, 2015
Rated 5.0 out of 5.0 by Awesome! This diamond cut wheel was a bit expensive, but honestly after using it was worth the money. I purchased a brand new dealt right angle grinder and used this yesterday, it worked very very well. I also rented a floor sander from my local hardware store and it worked but it was hard to control and was messy. This creates a lot of dust, but it certainly does the job. I am happy with my purchase, I could use this for further work as well. April 22, 2015
Rated 5.0 out of 5.0 by Simply Works! Needed to remove epoxy paint from basement floor. This really did the trick. Dust is the only drawback, but worth the hassle. Ground about 150 sf and wheel doesn't look worn at all. Great buy even at 40 bucks. April 29, 2015
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
