RE: [Homebrew_PCBs] Re: Drilling circuit boards on the cheap: [1 Attachment]

Purchased at a Ham Radio swap&shop. I drilled the eye out of a Lincoln penny with it once.
attached a photo of holes drilled with a #64 bit. The 64 bit gives a 64 hole. Same bit in a Dremel makes a hole half again bigger.
