Definition & Meaning of "impact driver"

What is an "impact driver"?

An impact driver is a power tool used to drive screws and fasteners into materials like wood, metal, or concrete. It works by delivering quick, strong bursts of rotational force, making it easier to drive screws without damaging the screw heads or requiring as much effort. Impact drivers are especially useful for tasks that involve large or long screws, as they can handle tough jobs that regular drills may struggle with. They are commonly used in construction, carpentry, and DIY projects.
