I have purchased a couple of high speed air powered die grinders from
<www.princessauto.com> . They sell them 2 ways: individually (CAN $30.00)
or as part of a kit with several bits and a plastic case ($70.00 Can). I
have not used them to drill PCB holes yet but they appear to have almost no
run-out. They spin FAST!
The high speed electric Dremel type tool I've used for drilling PC Boards
over the past many years looks very similar to a Dremel but has a label
that says "Metal Removal Corp". It has sleeve bearings, NOT ball bearings
and has exceptional run-out characteristics.
