It was @Maker assuming you're thinking of the tiny drill bit I'm thinking of
New drill bits for more flux capacitors. Fingerprint for scale (Also a scale bar for scale).
A few more jobs like this and I might finally get the Datron Neo I've been lusting after!

coincidentally the nickname we gave a manager at a previous job...because he was a small boring tool
that aside, tiny tooling amazes me every time i encounter them...even a 1mm drill bit baffles me as to how it doesnt just disintegrate immediately

I have a small bench drill by Medow's.....it's 3 phase and top speed is 23,000rpm....thats right no mistake on speed
I run it at 1/2 that speed for 1mm pilot drill holes....
how the bits don't disintegrate blows me away....I do use a little sud's tho...

jesus...and there is me moaning that my drills slowest speed of 600 is still to fast for most of what i do
23k rpm is crazyI remembered this thread whilst I was rifling through my drill drawer earlier this week.
I picked these up a few years ago, not because I’ll ever use them, just because they are mind-blowingly small, and always a great conversation piece!!
I have never seen a smaller drill than these, and cannot come to comprehend why anyone would need to drill a hole as small as this.
They are 0.05mm in diameter (or 2 thou) and taken in front of a mm rule. I think the shanks are 1mm to get some idea of scale. Maybe have a working depth of 0.5mm?

do they do those with through tool coolant?
The drills used for through vias on printed circuit boards can be quite small. The specified drill bit size is smaller than actual hole size, presumably to allow for runout, so e.g. 0.1mm drill for a 0.2mm through via. Normal PCB thickness is 1.6mm, though many PCBs these days are somewhat thinner, especially the tiny ones for consumer electronics e.g. bluetooth earphones.

Believe it or not simple ‘spit’ (saliva) makes a remarkable difference

I would have thought 11,500 was too fast anyway, but I’m no expert, I’d tend to use 500 to 1000 max on mild steel

Tiny drill bits - sterilise with fag lighter flame and bore thru trapped finger nails to release the blood.

I use mig wire fresh off the weld...or have been known to accidentally hit the same thumb a second time and split the nail...works well but I wouldn't recommend

I helped someone do that with a pin and an induction heater once, certainly not something I need to see or smell again.
