I decided to drill my brake rotor this past weekend since I needed to get rid of the squeak. I put the rotor on my lathe and gave it some sanding and deglazing, then on to the drill press. Wasn't as hard as what I read from many people. I used one regular metal/wood drill bit at 250RPM on my drill press with plenty of drilling fluid. I put a very slight chamfer on all the holes. I am well pleased with the results.
