6. Can I drill more than one sheet of metal at a time?
Yes, multiple layers being riveted together should be drilled together to ensure that the holes are aligned. Drill and set only one rivet initially because hammering will cause the metal to shift slightly, moving the holes out of alignment. After the first rivet is set, set a second rivet on the opposite side (called counter setting). This secures the metal so that it doesn’t continue shifting. All other holes can then be drilled and set.
