Alexandre,
You know you are absolutely right. I noticed my son's new dremel
came with what looked like a regular keyless drill chuck and he
liked it. So I got one and while it does have .001 to .003 (or
sometimes more) runout, it is consistant for the length of the
drill/tool, that is it is fairly well aligned with the spindle axis.
I always thought that collets were suppossed to be more accurate
than a 3-jaw drill chuck, but not in this case.
