Hi I need to cut some holes for buttons in a metal panel above my CP. Its about 3mm thick and I've dried drilling and a holesaw and nothing seems to be making any headway. Is there a particular tool thats suitable for this?, as at the moment I'm rapidly blunting my cutting tools on it. Cheers. |

I think what you are looking for is a bi-metal hole saw. Either that or a Greenlee punch. A regular hole saw just won't do. |

You'll want to use a drill press for best results. Otherwise you're going to need a very steady hand. |

This option may be slightly pricey. John |

bi-metal hole saw is the easiest solution. You can cut them handheld as well because they have a pilot bit that guides the saw. |
