10 diameters deep. It worked !. I'm sure it's probably not a big deal in aluminum, but it's the first time I've drilled anything that small. I can barely see the drill bit. :-).

Wow, that's quite a feat! ...I think.
You wouldn't have a photo or something, would you?
What cut parameters did you use?
Musta been lots of tiny, little pecks.... Smallest I've ever even tried was about 0.030" diameter.

HSMadvisor recommended 3.3"/min @6000rpm, peck .01". I pecked .006" because I'm chicken, but it worked, no broken bits, so I'm happy. Hopefully you can see the holes in the pic. They are in a spiral pattern.Quote:

That's pretty good. Run out is critical on small drills. I was watching a guy at work drilling .003 holes, can't even see the drills, and the flood coolant would break them! Whole different art below .015.
Yeah, THOSE are tiny! Thanks for the pic!Quote:
