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.

Had to cut a crawlspace access in my foundation, bought this wheel to clean up the edges before building a frame and it ate through the concrete no problem on my Milwaukee cordless grinder.

Performs well, made well.

Would Recommend

Worked great for shaping square concrete post caps for water runoff from wood posts. Didn't lose abrasive ability in an hour of grinding.

Only needs a light touch.

Would Recommend

Great little fringing wheel. It is very aggressive and will move concrete quickly. I used water to hold the dust in check. Great for small areas and close detail work.
