When your done slicing it will look like this.
Now use the cutoff wheel and cut out the rest stopping before the line. Once you have removed all of the slivers of metal turn the cutoff wheel upright and clean up the edge of the hole without grinding past your line.
Now switch out the cut off wheel for a deburring tip (shown in the next pick) And carefully trim the outer edge of your hole until your repair piece fits nice and snug like shown.
