I have gone to using flap disc in my 4-1/2" angle grinder and really love them. They last and last and last. But, I have only used 80 grit. I bought a10 pack. I have noticed that some times I wish I had a little courser grit. For instance taking the mill scale off of hot rolled steel bars, tubing and angle 80 grit seems to load up a little. What preferences do any of you guys have for this application?
