RF Prototyping on a Shoe Box

Yep, I've seen a drill bit that left pads. I'd like to find it again. Anyone have links?

Hello Jim,

No but it must be either something like a miniature hole cutter or a bit that looks similar to the spade bits for wood. Don't know if the name "spade bit" is right but they have a small center part and then a spike on either side.

Regards, Joerg

Has anyone seen a special drill-bit that might attach to a dremel minidill that could be used for cutting out circles in PCB board?

How big? I have a circle cutter for my Roto-Zip, which is just a fancy Drummed tool. The Roto-Zip will easily cut ceramic tile (with the appropriate carbide bit), so I wouldn't think FR4 would be a big deal.

I believe both the Roto-Zip and Dremmel tools have the same 1/8" collet, so the bits should be interchangeable.
