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 Joe Jimenez

I thought long and hard about ordering one of the discs and decided to start with the thinnest one. King Arthur's Tools Original and Patented Galahad Green Holey Fine Grit Tungsten Carbide Round Disc BUT when I first turned the disc on I was very surprised by the noticeable vibration! I checked it at all speeds from 1 to 4, and it wasn't until 3-4 that it became clear that this plate could still be used somehow. It is severely deformed and has a deviation of about 1mm during rotation, which is unacceptable for use! The pane only jumps open on the wooden surface! Is there really no factory quality control - after all, such deformation is obvious! this is what the disc looks like after a few minutes of work! The skew is so obvious - I don't know how to use a disc like that. I have discs from a competing company that are much better quality! I did not expect such a disappointing quality product and do not recommend it to other carpenters.
