Review on 🛠️ Linkhood 4-Inch Diamond Cup Grinding Wheel with 12-Segment Turbo Row - Heavy Duty Concrete Grinding Disc Tool for Angle Grinder - Ideal for Granite, Stone, Marble, Masonry, and Concrete Surfaces by Scott Richardson

If you're looking for a grinder to remove old concrete, paint or whatever from a surface, this thing is worth every penny. Perfect fit for my DeWalt drill, started sanding some floors and went to town. I was able to use it for 2 hours straight and the wheel still looked pristine. While this can create a mess, I will say that the slurry really speeds up the process and gets the job done better if you keep the surface wet. Much cheaper than anything you can buy at HD or Lowe's.
