I bought this to grind off porch paint. It made short work out of the job and I was able to smooth out areas where concrete repairs have been completed.

Very impressed with the grinding wheel. I thought I would need to buy more to finish the patio but there is plenty of material remaining on the wheel. It took approximately 8 hours to grind the paint off of the patio with measurements of 11' X 16'. The end results is a smoother concrete finish. It was very easy to maintain the exterior corners of the steps but I was unable to grind the inside of the stress/crack relief grooves. All in all, this diamond wheel easily attached to my grinder and preformed better then I had anticipated.

I had to remove about 3/4 of concrete bonded to an older concrete foundation. The newer concrete added over the older concrete foundation was securely bonded. I could not chip it off. Grinding was the only method for removal. I ended up using both grinding wheels and each still has some amount of usefulness left. I kept them just in case I needed to remove anymore material. I was very impressed with how they performed.

I was honestly shocked at the performance of this cup wheel. It last long enough to smooth the part of my garage floor I needed to do. I worked with it continually for over an hour and the wheel showed nearly no wear at all.

I was half expecting the cutters to wear down in a short time but hoping they'd last long enough to smooth the part of my garage floor I needed to do.

I have used this wheel to level some concrete to prevent tripping. And this was ideal for the job.

Good quality diamond grind wheel. Cuts great and still lots of life left after a long time grinding.

Everything came as expected. Very good quality of the diamonds, The whole process was really smooth.

I want to say it is great grinding wheels, better quality than what I bought locally, and the grit 16 cut so fast. I love it.

I want to say it is a great wheel, cutting my floor very fast, it is a powerful wheel.

Fast delivery, I use it with my hand machine to grind the concrete. Cut very fast.

It worked with my hand grinder, it cut realy fast. Good Wheel.

Look heavy duty. Haven't tried it yet.. Hopefully it will work fine

I wasn’t sure at first, but this thing performed super. Wore the first one out and then bought another. I would buy it again. I Had to grab the threshold to my garage doors

I have surface ground about 20 square feet of painted concrete block with this wheel so far and it barely shows signs of use. It removes material quickly and leaves an smooth surface as long as you keep it moving. If you stop it will dig in fast. It creates a massive amount of dust so a full face respirator is highly recommended.

After grinding approx 20sqm it still works fine. When wetgrinding a lot of dust gets bogged in between and needs no be cleaned every 1sqm or so. But good deal for the price.

A little expensive, but worth it.

The 7 diameter wheel needs a powerful grinder to drive it. Match the RPM ratings.

Appears solid and performs OK with a grinder.Rough grinds concrete and masonry OK just not sure how long it will last. But for the price it's great.

This diamond grinding wheel is almost indestructible! I've used it to remove old mortar and tile adhesive from over 2000 sq ft of reinforced concrete floors and it still has at least 50% of the blade thickness left. Very well balanced with factory balancing holes drilled on the back of the plate.
