I have a DIY 3 axis mill with a 1hp router. I would like to cut thin sheet metal (24 gauge or .02" thick). I would appreciate a recommendation for the following:

1. Bit type - something in 1/8" size - I don't need to cut with detail, just basic geometry. I don't know much about bit types so a link would be appreciated.

2. Router speed settings.

I'm not concerned about how fast I cut the project - just that it cuts safely.

Thanks.
