Correct. As I learned when shopping for them, if the word "chuck" appears anywhere in the description, it's already set up for straight-shank bits.
The MT2 spindle they're talking about is on the OTHER end of the chuck, where it goes up inside the drill press motor -- the spindle. You have to assemble these things yourself.
What you'll have is a metal cylinder with a MT2 attachment on one end, and the Jacobs attachment for the chuck on the other. You put the end with the MT2 attachment up into the motor end of the press, while the chuck attaches to the Jacobs attachment on the other end.
When you see "spindle: MT2," that tells you what type of receiving end lies up inside the motor. Other types include a threaded, screw-in type of attachment, and there are a couple others.
