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

This worked good for my use which was to grind down some high spots on my basement floor where the previous owner added a drain pipe in the floor. Only thing bad was a lot of dust. I also had on a dust shield for the shop vac , but the one I had went right back to Ebay because it was useless as far as pulling any dust. Just be careful with this because it removes the material fast!
