Joe Pieczyniski has a good video on machining very small diameter parts in the lathe.

Re: Drilling small holes
We keep our HLV fairly well aligned, but nothing NASA-like. No doubt more RPM would be nice but I bet I did them at 2000 or close. I thought it would be a disaster but was amazed at how easy it was.Harold_V wrote: ↑Wed Oct 20, 2021 3:58 pmWow! That's really impressive! The machine must have exceptional alignment, headstock to tailstock. Spells instant death for fragile cutters.Conrad_R_Hoffman wrote: ↑Wed Oct 20, 2021 3:41 pm Just recently I needed some small holes and bought some 0.0085" cobalt drill bits. They were far easier to use than I would have thought and I have little fear of going smaller, if necessary. No doubt I'd snap carbide instantly.
What speeds are at your disposal? Such a tiny drill would easily tolerate more than 10,000 rpm.
