There are also re-sharpened ones that are even cheaper. Unfortunately, one of the batches I bought were packaged with a piece of? plastic foam with the drills stuck into it, quite a few of them broke

Yes, try the carbide PCB drills. They're sharp and hard and will cut stuff that just laughs at high speed steel or even cobalt drills. BUT they are fragile and will break if you look at them sideways.

Yep, the PC drilling machines I have seen were branded DAK they used high speed electric drive spindles, 10K rpm?? and we used small collet held carbide drill bits, they were CNC?

There are "printed circuit board drills" that I believe are carbide. Amazon has inexpensive ones.? Professional industrial ones cost more.? The are all quite brittle and easy to break.? They are

yea , the guy does real nice work . I wish I had half his patience .

I watched a lot of his build on the QC.? Pretty nice job IMO.? Way above my pay grade, LOL!?
