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

Needed to level out several sections of concrete sidewalk that had rose about 1 - 1/4 at the corner of the joints. Had 3 section about 2' x 2'. Work great at lowering the high point down to the matching joints. Took about 4 hrs to do all three raised corners. Ran a small amount of water while grinding. I was amazed at how aggressive it was in grinding down the concrete. Showed only a little wear at the leading edge of the disk as I was really grinding at an angle to get the fastest cut possible, then change over to level grinding to level out the slope.
