[Land-speed] Drilling teeny holes...

[neil at dbelltech.com]

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.

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.
