What kind of accuracy do you need and will you lock the table when it gets to position? In case the drill kicks the table on entry.
How fast do you want to go hole to hole?
How heavy is the table in mass?
can the motors accelerate it and decelerate it without slipping.... or do you have encoder feed back.. one slip and every hole after that is in the wrong place and the whole part is scrap..
This is the stuff the stepper guys often don't tell you.
