Those circle cutters need a slow rotation rate and lots of patience on metal to prevent overheating. They work great in a drill press. |

I agree with the Greenlee Punch. You drill a sloppy pilot hole, assemble the punch *, and slowly tighten it with a ratchet. It will make a perfectly clean, perfectly round, precisely placed hole. * It consists of 3 parts, a punch on one side of your stock, a die on the other side of your stock, and a bolt that connects the two through the pilot hole. - Mark |

And super easy and quick... ...but what about the thickness? 3mm? Seems really thick. Anybody used a greenlee on something this thick? |
