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

A cordless drill is versatile and suitable for a wide range of tasks, such as drilling holes and driving screws. It provides consistent torque for general use. An impact driver, on the other hand, delivers high torque and quick bursts of power, making it ideal for driving long screws or bolts into tough materials. Impact drivers are more efficient for heavy-duty tasks, while cordless drills are better for general-purpose use.
