How to drill 1mm diameter holes? My drills won't even hold the bit!
-
Trying to enlarge some holes on an incorrectly fab'd PCB. I have a 1mm diameter drlll bit, but it turns out none of my drills will hold it--their chucks have a more than 1mm diameter void when closed. I never knew until now, when the chips are down. So, for the future, what drills will hold small bits like this?
As a one-off, I held the bit with a pair of pliers and crudely rotated the PCB around it to drill the 3 holes, but it was awkward and I never want to have to do that again. As a one-off, it did work though.

@NeverDie https://www.aliexpress.com/item/32738503593.html special bits, that has the same diameter of the tail side, and will fit the standard drill. Or you can buy a drill with small jaws, or just another chuck, that will fit your drill.
I am using dremel tool with a drill chuck bought separately https://www.dremel.com/us/en/p/4486-2615004486 -
