Eh, fair point. But sometimes you need to pilot hole a stud (like for hanging a TV mount). Tapping in a hole with a screwdriver also sounds less than ideal. You might twist the shank when you strike and overbore the opening, get a loose fit, etc.

I bought the Dewalt drill/driver combo set like 10 years ago. $100 on sale, worth every penny. I'm sure B&D or Ryobi sells an even cheaper set.

Drill bits chucked in drivers drill shitty holes. Too much runout. You need a drill, particularly for things like pilot holes for wall anchors, etc.
