I second that. For larger holes, I tape over with masking tape, draw out the cut-out. And use the hole punch to nibble away the tin to make the cut-out. Works a lot better than any drilling. |

I picked up a set of these in B&Q www.diy.com/diy...ELAID=266914431. They've been quite useful for adjusting holes, especially the conical one. Available in the Perth store according to the website. |

I haven't found a way to use the paper punch on the lid I use a 3mm drill and then enlarge with a reamer |

It's very heavy duty... mine goes through Altoids tins with ease. The only drawbacks are: (1) for casework there are only 3 useful sized punches- the rest being too small; and (2) the punches are sized in INCHES not MMs. BTW - HF also has a larger (and more expensive) bench-mountable model that I may try. |

They have a 6mm shank, so possibly not. I use them in a cordless drill. They're not particularly high quality tools, those Bosch rotary files, but they'll deal with an Altoids tin. A proper reamer or step drill is probably OTT for such thin metal. In fact, the very thinness of the mint tin metal makes it quite awkward to deal with IMO. Also, because a reamer is a proper cutting tool, it might remove too much metal too easily, leaving you with too big a hole. The crappier Bosch conical file removes metal more slowly and makes slip-ups less likely. Fred_Fred's method is a good one, or you could try one of the Black & Decker 'Bullet' drill bits, which centre themselves better and cut flimsy materials like a mint tin more cleanly than a conventional twist drill. It will also help if you can hold a piece of wood behind the metal to prevent it from flexing too much or collapsing while you drill. I started using old tobacco tins bought off eBay to case Cmoys. Solid and slightly easier to work with. And 20% cooler. [Edited by miles hand on 03-21-2009 at 08:54 PM.] |

There is a rotary file set for the dremel. Jack's Toolshed has it for about $10. My DRemel kit came with some rotary files. I need to check what's in it.
