4 jaw?

Just to set the record straight, a Bison is a pretty good chuck, but it is not "one of the best chucks money can buy".

For examples of those, look to Mikey's post above.

Agreed, I love both my Bison Set-Tru chucks but I'd take a Samchully, Kitagawa, PB, or Rohm chuck over Bison any day. There are even better chucks out there in the CNC & hydraulic chuck world.
