What are the key differences between an impact driver and a drill, and how do these differences impact their performance and usability in various tasks?

An impact driver delivers higher torque and rotational force compared to a drill, making it better for driving screws and fasteners into tough materials. The impact driver's quick bursts of power also prevent stripping screws. On the other hand, a drill is more versatile and can be used for drilling holes in various materials. The impact driver is more efficient for tasks requiring high torque, while the drill is better for general drilling and driving tasks.
