I checked all of the hardware stores in my area and I can buy 1/32 (~ 0.79mm) and 3/64 inch (~ 1.2mm) drill bits. No source in my area carries bits which are between those two sizes which would then be the perfect hole size for various pin headers (like the IDC plugs).
Rather than me wait 4+ weeks in hopes that I can get sufficient perfect drill bits online at the right price (from china?), I'm looking for another feasible (if possible) way to make my own sufficient size hole for the IDC plugs to fit in. I tried fitting them in a 1/32 inch hole and that doesn't work. If I use 3/64 inch, the plug fits loosely and part of the supporting track is gone due to the hole size. That's why I'm interested in a hole size that's in-between, something like 1mm in size.
The only thing I could think of which can rather be dangerous is to use a mini motorized drill and move the motor so the drill (while it's spinning) is at a 20 degree angle relative to the board itself and then keep adjusting the motor so that the drill points at every direction at some point. Another drawback to this method is that the drill bits can easily break.
I also looked into sawing the PCB with the drill bit. I managed to do this before with bigger drill bits when I didn't have the tools in order to create the support holes for the serial port. But I'm afraid if I do this with small bits, I'll break them.
So my question is, other than waiting 4+ weeks online for a chance to receive drill bits in the mail after ordering them, is there a good way that I can use to create a 1mm hole given that the closest bit sizes available to me are 1/32 inch and 3/64 inch?
