Are double angle collets any better? I'm getting a set of DA400 that I plan
on using with my Nichols Miller so I don't have to disassemble the drawbar
to change endmill sizes.

In theory, the double angle collets are not pulled towards the spindle
as they tighten so the cutter extension or offset does not change.

Also the collets in many of the double angle collets (like the ER
series) have a much larger gripping range. Those typically have a 1
mm or .040" range while collets like R8 and 5C only have a few
thousandths.
