Review on 🔧 King Arthur's Tools Galahad Tungsten Carbide Disc - Original Round Coarse Blue Holey Disc for Woodworking, Shaping, and Smoothing, Fits Most 115-125mm Angle Grinders, Standard 4 1/2 Inches #47851 RCB by Juan Gomez

I clean common logs in a log house and it removes the oxidized layer of wood very quickly and the tool does not clog. The reason it didn't get a five star rating is that the teeth wear out quickly. I used it for 5 hours of grinding and after another 5 hours the teeth are polished to the point where they are unusable. This is an expensive tool that wears out quickly. I would have to buy two more of these tools to get the job done, which is more than I'm willing to invest in grinding tools. Great idea, but not for long.
