Review on Weiler Threaded Crimped Diameter Bristle: Achieve Optimal Cleaning Performance by Darrell Beecher

I used this to repair a large log railing with a 4 inch angle grinder. I tried 4 different sizes and 3 brands of wire cup brushes. They all did an impressive job of quickly removing old weathered wood and leaving a beautiful finish before painting or staining. I have tried 3, 3.5, 4 and 5 inch brushes. The 3 inch angle grinder turned out to be the best for the four inch angle grinder. Weiler and Forney brushes have served well. The DeWalt brush broke and lost its bristles very quickly. price matters. If you are thinking about using this tool for this app, be sure to wear long sleeves and a face mask. At the end of the day, your clothes will be covered in stubble.
