I have a belt sander for aggressive wood removal, but it's large and awkward to use aside from on flat boards. I have ROS's for both aggressive wood removal (36 or 40 grit) or for finish sanding. I've heard people mention using flap discs on an angle grinder for wood removal but have no direct experience doing that. I'd appreciate input for situations where a flap disc on an angle grinder would be a better option than either a belt sander or ROS. Please include the recommended type of flap disc for these situations.
Also aside from working wood, what other uses are flap discs besides prepping metal for welding?
Thanks.
