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

I found nothing to dislike about this finishing tool! I used it to clean up and smooth the floor and walls of my shower and bathroom after I removed the old tiles. The floor is concrete, and the walls are plaster-the diamond studded grinding wheel easily removed all the old quick-set adhesive and smoothed the plaster and concrete, so that the new tile would go on with no problems. There was an area of the floor that had a slight dome shape, and I used the tool to grind the concrete down to level with the surrounding floor-no problem. After all the work, inspection of the grinding face of the disc revealed only a slight rounding of the extreme edges of the actual grinding surface-otherwise the face looked like new. It's ready for the next big job!
