Review on LUCKUT Grinding Grinder Aggressive Grinders 5 by Theodore Huynh

I'm an amateur welder and I make a lot of mistakes. Pretty much everything I weld is a mistake and needs a lot of cleaning up. These grinding wheels helped me a lot with surface preparation. I have one of these discs on my cheap HF grinder that I use to clean the metal on both sides of the weld before anything sparkles. It really makes a big difference how well things stick. When I'm done, I use the same disc to go over the area and remove the flux and spatter. I use another HF grinder with an aggressive rock to fix my damn mistakes. I have used a twisted wire wheel and these grinding wheels are much better.
