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.

Would Not RecommendPurchased this tool after trying to chisel off concrete left behind a removed tile floor on a 2 story balcony. Passed this over with a small corded Hitachi grinder and got it smooth enough to apply an asphalt primer to install a self adhered modidorf membrane. Excellent product.

Great on roughing up porcelain
Would RecommendI am laying new tile on top of old. I read that the old porcelain tiles needed to be roughened up first. I tried using an angle grinder with a composite grinding wheel and the porcelain surface just blackened and smoked. This diamond wheel did the trick. It burrowed right into the porcelain with such speed I was able to roughen up the entire bathroom in only 10 minutes. Wow.

After spending 4 days with a pressure washer and 2 days with high dollar chemicals trying to get many layers of paint off my house,I read the reviews on this miracle grinder. I have been able to remove more paint with this in 4 hours then I did in 4 days with washer. Very dusty, but worth it. I like it so much I went and bought his 7 inch big brother.

Back to the Grind
Would RecommendI used this to smooth off my concrete floor prior to applying epoxy. The blade cut right through the excess concrete on my floor with ease! The blade also didn’t wear prematurely.
