Mayf;
Printed circuit board (PCB) shops routinely drill holes that size and even
smaller; they use solid carbide drills with a standardized 1/8" shank. You
can find these drills on eBay now & then. Use a collet- type holder such as
a tap wrench, etc. Use a light feed and high RPM with a little kerosene for
lubricant on aluminum.

Subject: [Land-speed] Drilling teeny holes...
Other than very carefully, how does one go about drilling very small
holes, holes on the order of 0.020 - 0.040 diameter? How do you chuck
something that small? And I suspect that sharpening drills that small is
not gonna happen. Can hardly see drill bits that small..
I would be drilling in aluminum.
