excellent for cleaning and trimming surfaces

cuts concrete quickly. I needed to refinish a floor tile and scraping a thin layer off the backing and cutting new grooves made the job quicker.

Pros
  • excellent overall performance
Cons
  • ineffective

Effective for removing tile putty!

I recently posted about the old ugly tiles in the kitchen and ended up with a ton of stubborn putty. These discs allowed for quick removal without chewing up the subfloor.

Pros
  • Easy to use
Cons
  • Good overall but...

Damned! Worked great

We had to sand down a fairly thin layer after removing the tile and it worked like a charm on the sander. Warning, you must connect your grinder to a good dust extractor! Using it without dust extraction is not the best time at all.

Pros
  • GOLS certified
Cons
  • I'll write back later

One wheel didn't fit

The 4 inch wheel didn't have room for my locking flange making it unusable for me. However, the 4.5" wheel was fully locked onto my mandrel, making it usable. . It's pretty good for sanding a cinder block wall. However, the number of diamonds on the wheel appeared rather meager. I haven't used it enough to determine its lifespan. NONE of the wheels listed at Revain have sufficient sizing information to allow you to select the correct wheel. Need more specifications to shine. My Hitachi (now…

  • Enjoy

It worked exactly as it should.

I had a cobblestone chain that I needed to widen, but the cobblestones were old and I couldn't find them. I decided to fill in the paths with concrete and shape them with a trowel. The result is a very gross, unprofessional looking mess. I bought this grinding wheel to smooth it. It worked very well, but when I finished I was left with a bare metal wheel. I'm okay with that because it did the job I needed and I don't think I'll ever have to do it again. I've never had to use a second, thinner…

Pros
  • Satisfied so far
Cons
  • Compatibility

Amazing tool. Old motar tiles removed.

Using a sledgehammer and impact drill I removed a 50 year old pink bathroom floor tile. As the tile came out, most of the grout stayed behind, creating a rough surface. There was no way I wanted to pour floor levelers and raise the floor even higher, plus cost and time. Tried it out on a Dewalt battery powered angle grinder. The grout came off so easily I couldn't believe it. The old concrete was harder than mortar, and the grinder went right over the concrete, making a level surface suitable…

Pros
  • Great for a small home
Cons
  • Questionable purchase for the elderly

Much better than expected

I didn't have high hopes but it was cheap and claimed to do it so I gave it a try. Our foundation was expanded so we were about 25 feet by 8 inches wide which was about a half inch to an inch high which was fine until we decided to finish the basement. I chose these two packs because I thought that together they would give me a good idea of how many grinding wheels of this type I would need. Well I've sanded the whole thing with just 1 sanding wheel and it still looks almost new, I really…
