I used the dremel with no problem. The key was to go with the center punch and to drill for only a couple seconds at a time making sure your on track needless to say a lot of start-stop-start-stop. Honestly I had more issues using the small drill press my father handed over to me. What really will help if you have to go the dremel route is to get a foot pedal switch (if you've got the corded style dremel that is). Either way with those extremely small bits on a not so even surface you'll need to choke up on the bit with the chuck to help increase the stability of the bit your using.
