EDiamondTools7" Diamond Grinding Wheels for Concrete or Masonry, 12 Turbo Segments, #30/40 Grit, Medium Bond, 5/8"-11 Arbor

I needed to level out the concrete outside a garage door. I got this and attached it to my angle grinder. It works great. It removed exactly what I wanted it to and with varying pressure it can remove a lot or a little. I am very pleased with this grinding wheel. It looks like it will last a long time with little to no wear after completing my project.

I uses this with a Harbor Freight 15 amp Hercules Grinder and shaved down the high corners of lifted concrete slabs in my backyard. It worked great! It felt like I was sanding through wood. In some spots I ground through 1.5 inches. It made lots of dust, so if you're new to all this like me, I recommend getting the dust shroud for the grinder. It helps a little bit.

Concrete Patio pavers have these bumps on the side to keep them in place but I needed to fit a few along a smooth surface and this grinding wheel worked wonders with my grinder. It was so fast.

I had to grind part of my basement floor to level before putting engineered wood flooring down. I first bought a name-brand bringing disk from a local bigbox store. That one cost about 3X more and sucked. I worked hard but made little progress. Then I decided to buy this one. It worked great. It was easy to control the grinder and it worked quick and evenly. I wish I had purchased this one originally. The only (very slight) drawback is that the holes in the disk where the anger grinder wrench fits were a bit smaller than the spread on my wrench. I still was able to secure the disk and remove it, but that took a bit more effort than I expected.

I got a standard Makita plastic vacuum dust shroud for the Makita 7" grinder. I had to actually grind off a bit of the back face of the screw collar of this wheel, otherwise the wheel would stick out too far from the plastic and would not seal well against the floor. Once set up however, the combination pretty much tore through my concrete basement floor, 400sq ft., to remove very old paint for tile prep. Was able to do some shallow lip removal to level some spots, but any area more than about 1/8" too high would be a slow process to grind down with this setup. The combination left a super clean surface perfect for tile laying, probably took about the same time as a large floor grinder if you account for rental, transport, return, and they weigh like 120lbs or something awful. Glad I went this route, for a while I was really scratching my head on how to strip that floor, never done that kind of job before. The diamond abrasive still has a lot of life left, not really noticeable wear. Kind of amazing considering 60 year old concrete.

It fit and worked well in my corded 4½" Milwaukee angle grinder.

Most affordable option out there. Well built. 2nd buy, I'm sure there will be a 3rd.

I had some areas of my driveway where the top surface had spalled, leaving exposed aggregate. I followed YouTube videos advising a broom finish and did not like the results (I previously just trowled the finish and it was fine). This tool was my solution to fixing the problem and got a nice, smooth finish. I then used it to fill small bird egg-sized holes in the driveway. I just applied some mortar with little attempt at trowelling. After hardening I ground it down smoothly with this tool - easy, peasy! If you have raised concrete slabs this tool can cut them down to eliminate tripping hazards.
