Manual Impact Driver (2001431) In Stock Now

The main difference between a drill and an electric impact driver boils down to power and rotational action. Unlike drills, impact drivers are made with quick release shanks that accept all one-quarter-inch hex driver bits. Impact drivers produce lots of rotational force, capable of driving the largest wood screws in seconds.

Internal mechanisms allow impact drivers to produce more torque than drills, and in quick bursts. These bursts or “impacts” happen up to 50 times a second, giving impact drivers their name. They also rotate their bits in a two-steps-forward-one-step-back pattern, engaging and driving screws more effectively than drills. 

There are some times you shouldn’t use it, though. For example, the high speeds and violent impacts they generate aren’t great for small screws like the ones you use on cabinets.
