Ed is referring to what is called the “throat capacity” of the drill press. It is the distance from the center of the chuck (where the bit goes) to the closest edge of the column on which the drill is mounted.
It is the maximum distance from the edge of the piece you are drilling that you can drill before the drill press column/post gets in the way.
