I have a couple of twin backboxes with single FCUs with flush, press-on metal faceplates. It would have been too much to ask for Crabtree to make the faceplates narrow enough to fit them both on, so I need to cut (or grind or sand?) a few mm off the edges.
The builders left my kitchen without properly-cut holes in the tiling to fit the mains sockets. Again, I need to cut a few mm off the tiles.
I'm not sure that I have any tools to deal with either situation. Will a Dremel perform both tasks? If not, what's best? (If not one tool, then two.)
