Review on 7" Diamond Grinding Wheels For Concrete Or Masonry, 24 Turbo Segments, 30/40 Grit, Medium Bond, 5/8"-11 Arbor by Derrick Villarreal

I had to level and resurface a concrete patio. This was great for preparing 200 sq ft of concrete to be resurfaced. Grinding down anything more than 1/8” with this and a hand grinder is a bit much, but not because of this cup. I tried it out because it was a little bit cheaper than the ones with tool manufacturer branding, and I’m glad I did as a DIYer.
