Useless video. I wanted to know how to choose the drill bit for the job not what are all the different drill bits. I wanted to know if I have something to hang say a picture how do I choose the drill bit for that hanger. That would've been useful.
The main difference is a drill is intended for drilling or boring holes. You can also use them as a powered screwdriver is you set the torque on a low setting. An impact driver is designed to drive fasteners, lag bolts, longer screws, or even when you have a large amount of screws to fasten.
