KSEIBI 644040 Diamond Concrete Grinding Wheel 7 inch for Polishing and Cleaning Stone Concrete Surface, Cement, Marble, Rock, Granite, and Thinset Removing, Angle Grinder Wheels Cup

This wheel is much better than I anticipated. I first used it to smooth some rough edges on poured 5k concrete. After about 20 min of use it was still going strong.I then used it to contour and grind out some patio pavers around a pipe. Once again no issues. It does take a bit of power to run as it drained my milwaukee 5ahr battery in about 5 min or heavy use. 2nd battery and it kept going. Very pleased with performance and build for the price!

Great value- used it to grind about 1/2 inch off of heavily rock and stone filled old concrete and barely showed wear doing about a foot and half square. Did not fit properly in my Makita grinder without shimming/washers but I made it work

I needed to redo a large section of pool tiles that fell off during the winter. There was a large amount of thinset mortar clinging to the concrete wall of the pool, and trying to chip it all away was a nightmare. I decided to use this grinding wheel to carefully grind off the mortar. It definitely did the job, I just had to be careful not to go too deep because it will also grind away the concrete. The grinding wheel barely looks used, so I think it will last through any other jobs I may need to do later. Good value for the price!

I bought this to level out the side of a stone for a project I was working on. Ultimately I am polishing the edge of this stone for Address Number to be mounted. I was concerned it was going to take me a while with my angle grinder to get the area level. Well not with this wheel. For an area probably 12" wide by 14" tall, I was able to take it down to level in about 15 minutes. Some of the areas were 2 to 3" proud of level and the whole area needed to be ground down about 1/2 inch. I had to be careful as it was going so fast I was worried I could have easily gone too far. Jumped from this to Polishing Wheels and the project is looking really great. This is definitely a good product and when I pulled it off it still looked like new so I will get many more uses out of it. Highly recommend for a stone project.

This blade really worked great! It helped me remove a few layers of acrylic paint, thinset, and spalling. Saved me thousands from hiring it done. Blade held up well for the whole job. Great price too compared to big box places.

Works great!

Works well to round off raised sections of patio slab. Not as aggressive as a larger grinder, but very good for a 4-1/2" disk. LOTS OF DUST!

Did well grinding stone at a good price

Used it more than a hundred times. Perfect everytime. Does a great job grinding.

Purchased this to remove leftover tile floor grout off a concrete floor. Couple tips that really help for removing the grout from a concrete floor. Lay a very wet towel over the grout for a couple hours so the moisture wicks through the grout and a bit of the cement floor. This keeps the dust way down, doesn't throw up water and cuts through the grout like butter. Much better than trying to grind when dry. Likely extends the life of the cutter as well. Just be careful as water and electrical tools don't mix, just don't crazy on the water, but most modern tools are double insulated.

I used the grinding wheel to remove flaking paint from concrete. It cut through the paint and scuffed the concrete. It only needs mild pressure otherwise the wheel will cut into the concrete. It prepped the surface well as i am going to tile over the concrete.

Used this to clean the front step from all the tile junk. Chiseled off the tiles, or tried to, and finished it off with this. Worked really well. The corners suck because round and all but apart from that, alls good.

I used this for about 8 hours to remove 2 layers of flaking paint on concrete sidewalk and it was still working fine when I finished. It leaves a fairly smooth surface and did the job to my complete satisfaction but you need to wear a mask because fine concrete dust flies everywhere.
