It is the size of an object that you can drill to the center. For example,
a 12" drill press allows you to drill up to 6" from the column. Basically
you take the 'size' and divide in half, and that gives you the depth from
the chuck axis to the column.

When I see a 9" or 12" or 15" drill press, what
exactly is that measurement?

is that 9" (or other) the distance from the bottom
of the table to the drill bit "chuck" or how deep
of an item you can put into the drill press before
it hits the "back/rear" post?

Thanks for your help.
