Are there any pin vises suitable for CNC drilling at high speeds for micro

I think (in printed circuit board drilling) the usual scheme is to use a collet
(0.125") and a suitable shank size on the microdrill. So, does a collet
chuck work for you? I'm dubious that a 'pin vise' is going to be well
enough balanced to run at the high RPMs a microdrill calls for.

If he is looking for an small adjustable chuck Dremel has one that
might work:

Obviously made for high RPM but who knows on runout... Only ~$9
though.

I've always used these drills in collets. I do have one of the little chucks and it's pretty good, but I don't know that it's good enough.

There's got to be a bunch of busted dremel tools out there - bad bearings, bad motors, bad speed controls. Ought to be able to find one super cheap.
