I need to drill 1,280 pocket holes! I have a DeWalt 14.4 that is in good condition but I know the batteries can't keep up with me. My son has the same drill and I can get his batteries, charger and drill. I was thinking about rotating, not only the batteries but the drills as well. Is this just too much demand for cordless drill?

If you guys think I should buy a corded drill (probably a 3/8), which one would have enough poop to hold up to this rather unusual demand?
