Nov 12, 2026, 12:16 AMi have this batch of amazingly trash drill bits in small metric sizes. idk what steel they are but it's definitely not any kind of tool steel. attempting to drill metal with them usually ends with them being twisted into a shape that is definitely not what drill bit flutes should look like
but this does allow me to do tricks like sticking one in the lathe and turning down the shank to fit in a pin vise, for use as a hand tool for reaming m3 holes in plastic :3

@emily I do not know when I made this, but it has been one of the handiest tools ever.
Nov 12, 2026, 12:26 AM@RueNahcMohr I have a few handles like that but none that take a round shank. Maybe I should have milled square faces on it to use in a tap wrench.
@emily Makes me wonder do they make wood working drill bits that are different from more common ones?
