Enco has their own brand (Chiwandian, I'm sure) drill chuck arbor for
$4.22 & a Jacobs brand one for $17.75. I'm assuming that there is a
difference in quality, specifically runout, but is the Jacobs one 4x
better? For use in a drill press (not lathe tailstock), do you think
the "Enco" one would be acceptable?

The arbors:

(Ummm ... the price on the catalog page is $4.22, but ordered it's $4.44.)

An **** - Enco won't allow direct access to those pages. You'll have to
go to Use-enco:

& search for parts 290-3236 & 890-9531.

All of that cheaper stuff always worked fine for me.

As all that kind of tooling is CNC machined no matter the origin, runout
and taper error should be negligable.

Unless the operator, a former field hand, crashed the lathe and didn't tell his
supervisor.

I got the "Enco" arbor today - it's a Phase II. Maybe they called
"Enco" 'cause the actual manufacturer can vary. If I'd known it was
going to be a Phase II, I wouldn't even have asked about its acceptability.
