What Customers Are Saying

This diamond grinding wheel is an effective tool for quickly grinding and smoothing concrete surfaces. It is described as durable and aggressive, able to remove tough materials like old tile adhesive and paint. However, it does create significant dust, so using it with a dust shroud or shop vac is highly recommended. Some users noted it can leave grinding marks if not used carefully, and that it is an expensive tool. Overall, this is a powerful and effective concrete surface preparation tool, but users should be prepared for the mess and take proper safety precautions.

Works fast with little effort

Would Recommend

I first tried a silicon carbide grinding wheel to grind down some cracks in my driveway. It took me over an hour to do 16" and it wasn't an even surface yet. It was worn down to the point I needed a new wheel, I got one of these Dewalt diamond grinding wheels and did 4 feet in an hour and it was an even surface. This grinding wheel took the concrete down fast with just a little pressure on the grinding surface and it hasn't worn down much from when it was new.

Very good to flatten uneven brick surfaces

Would Recommend

I used it to even out the floor of my pizza oven. Very nice to work with, but it can be a little too aggressive at times if you’re not careful. Maybe because of the small circumference. It was a bit more than I thought it should be but as long as it lasts I will be happy.

Tough on concrete

Would Recommend

Diamond cutting cup is great for grinding down concrete. I used this to level out uneven sections of my patio and garage floor. While I haven't had much time to use it, it seems durable and I expect it to last.

Made quick work of thinset!

Would Recommend

I replaced the old tile in my kitchen with LVP, and that required getting the floor back down to the plywood. After spending a good bit of time attacking the thinset with a floor scraper, I went to Lowe’s and picked up this fantastic grinding wheel. It took a little practice to learn how to avoid gouging the wood, but once I got the hang of it, it just ate through the rest of the project. Huge, huge timesaver and much better end result.
