I want to put holes in about 50 bottle caps today. Last time I used a drill, but needed to file/sand down the bottom area where drilled as it was protruding.
Am guessing that the Dremel would do this better, but do not know which bit to use.
Does a hollow, diamond bit seem right? Slower speed?
Thanks

Thanks I dont think using a diamond bit to drill metal is a good idea. The metal will clog up the diamonds. Use a regular carbide tip bit. Did you use a drill press last time, or drill by hand. If a drill press clamp a piece of hardwood to the table and dont apply too much pressure when drilling. The hardwood underneath should keep the ottom side of the hole from deforming and if the wood is clamped in place, each cap you drill will be over the same hole in the wood so each cap will have support. |

In addition to herb 's good advice to clamp a piece of hardwood to the drill press table, glue two small pieces of wood to that hardwood to form a "V". That will form a stop that you can push the bottle caps against. That has two benefits: 1) all the holes will be in the same location, and 2) your fingers will be safer!  |

Drilled by hand. Do not have a drill press. Had a black of wood under where I was drilling. Used a carbide bit.
The hole goes in the edge of the cap.

Perhaps clamping a length of dowel or broomstick in a vise could help by backing the inside of the cab's edge. Without a drill press, you'd have to rotate the dowel after a drilling several caps if the hole in the dowel becomes enlarged.
Useful?

I would just use a hammer and a nail and file off the back side, real quick to punch the hole and a lot safer. you could punch from the top and leave the protusions on the inside of cap. don't know what you are doing it them.

Here is one I tried to do using a drill. The edges are pretty banged up. I can clean the edges and apply black nail polish, but was hoping there might be a Dremel bit that would allow for a cleaner hole.  I drilled this from the inner edge out. |

Drilling thin metal is difficult, and can be dangerous. Always wear safety glasses as bits will break and fly in any direction. That hole looks to me as if the drill bit is rotating much too slowly. Try getting a bit that will fit in your Dremel and drill at about half speed, you should end up with a reasonably neat hole but still might have a few sharp edges that should clean up with a diamond Dremel bit.
Don't worry about steel clogging the diamonds, it shouldn't be a problem, if it is just give a squirt of WD40 to lubricate the bit.

I would drill it with a real small drill bit. just big enough to get jump ring into. if I had a bottle cap I would try it.

Lucky I had a beer last night. I just tried it, a small drill bit that comes with some of the Dremel extras kits works great, nice and neat, about half speed is about right.
Even better is the little conical burr, that cuts a very nice neat hole and doesn't wander around when starting the hole, about half speed is right for that too.
Diamond bits are useless.
Clamp the cap in your jewellery vice, that gives you both hands to keep the Dremel nice and steady. I drilled from the outside.

Drank more than a few of those during the 10 years I was in and out of Cairns, QLD. |

😂 I know of a cabin where they don’t throw any away, it’s part of the decor, and there are bottle caps all over piled on the shelf by the stairway.

Thanks for the suggestions. Will see if I have the cone bit. Also try running at half speed.
My smaller dremel (off brand) drill bits have too small of a shank to fit in the dremel. Will see if there are any shank adapters.
I do not have a jewelry vice,but will try to rig something up with a larger vice.
Yes, I am wearing safety glasses.
Will try again today and see what happens.

If you have a larger vice no problems, all you are doing is freeing a hand.
The extras kits are available all over the place (here in Aus anyway)they have the different size collets and the cone shaped burr and are cheap (off brand of coarse) the Dremel kits cost a bit more but have them too.

The hammer and nail works just as well

I was using the hammer/nail method. It took a lot of time to file each hole down and repaint.
