The Angle Grinder Wheels You Need for Fabrication - Roundforge

Note that we've ground out the pitting caused by the corrosion process. This means that we've also reduced the overall thickness of the workpiece in those spots. You generally should not be grinding out 1/8" deep pits on 1/4" material, since you're reducing the strength of that area to 1/8".
