Review on OCR Concrete Diamond Grinding Grinder by Danierl Temple

I was very impressed with this sanding attachment. When I saw that there were many different ones for sale on the website I settled on this one because of the price and simply because it looked solid. As you can see in my video, this thing completely ate the slate countertop I was working on and sharpened it by almost a quarter of an inch in a very short time. Yes, it's difficult to get even soft stone perfectly sharpened with this sharpening attachment, but it's a great first step. I've also used this sander for initial sanding of rough barn wood and it worked well. Regrinding takes much less time. It's a simple tool that gets the job done and lasts longer than a grinding wheel. So i really like it.
