This doesn’t track. You can do way better with a manual mill and, as the other poster mentioned, a 2d paper template with some spray glue will do fine in a pinch. Drilling steel will heat the bit up enough to melt plastic anyway. You could set drill bushings but they won’t be perfect and will drift a bit once they heat up.
