holds up when grinding brick. easy on, easy off.

Bought this to grind a raised crack in a sidewalk...worked BETTER than I hoped Took off over an inch of concrete about 3 ft wide in minutes with a $30.grinder ( also bought on Amazon)

I have a slab of concrete on my sidewalk where one side has sunk and raised the other side a significant amount (~ 3/4 to 1 in). This make quick work of the problem. I was able to flatten out the concrete to where there was no longer a tripping hazard. The grinding cup is still in great condition. Theres a couple of raised areas in my basement from old support beams I may tackle next.

This grinding wheel worked great! I used it to grind down a ledge on my sidewalk. It was a decent ledge and this thing ate it up. I would 100% reccomend it.

Fantastic on aged concrete, so-so on premixed thinset (white garbage). I was able to grind out 100 of floor cracks and lumps in no time. Not as effective against softer materials like white thinset but thats to be expected. Definitely use a dust shroud, my smaller project produced a few pounds of very nasty dust. Excellent value!

used for sanding my concrete pool, worked perfect good quality.

I cant recommend this for a large project, but its good enough for a small project, like taking the edge off of uneven concrete walkway. It takes some repeated back-and-forth, but it does the job.

I used this to remove thinset tile mortar and it did the job but only lasted for about 90 - 100 square feet. After that the teeth were worn down almost to nothing. If you need to do a large area I would suggest going with something a little more durable/harder material teeth or get a bunch of these knowing you are going to burn through them quickly.

item as I needed Thank you
