A little while ago I inquired here about an SPI keyless chuck. Comments
were favorable & I bought one.

I just got around to checking it with a dial indicator & I'm really
impressed. I put the SPI chuck (Swiss brand, but made in Taiwan) on
the Enco (Phase II) arbor (made in China) & mounted them on my HSM
Delta drill press (made in Taiwan). My indicator reads to .001, so I
can't
be sure what the TIR is precisely - cause it's less than .001. Probably
.0005!

What did you have in the chuck? And how far below the chuck did you take the
readings?
