VEXTA STEPPER HELP

I have 3 VEXTS PH265M-31 steppers, .9 degrees, 2 phase 6 volt, .85 amp.

Does anyone on the list have any information on these units, and are they big
enough for a SHERLINE Mill, direct drive.

Any help would be greatly appreciated. Especially the specifications. And
the wiring diagram, 6 wire.
White, yellow, green, black, blue, and red. I have not put a meter to them
yet.
Thanks,
bill
