Sort of like the one in this picture.

I've got 2 of these in my little workshop in the garage... not as good quality as the one in photo... but do you have to hit it with a hammer or something?
Thanks.

They are used to loosen or tighten screws without stripping the heads!
For example, the screws that hold the door latch on a car door are very tight. An impact driver is used (yes you hit it with a hammer) to put pressure on the screw and turn it at the same time! The impact forces the screwdriver into the screw, and gives it a better "bite".
I have one in my tool box. I seldom need it, but when I do, it is good to have!

That didnt look like an impact driver. Just a nice gripped screwdriver kit. An impact driver is usually metal with a flat on the end to hit with hammer. You have the screwdriver end in a stubborn screw that is too stuck to turn with a normal screwdriver or ratchet set. You bang the thing with the hammer and the gear inside torques the screw loose (hopefully)

impact drivers work really good for getting the screws out of the drums and rotors on ford and you use the hammer to seat the bit
in the the screw and then turn it in the right direction and hit it. the screw should turn a little with each hit

Impact drivers have an hammer effect to loosen nuts , usually air driven , you must have seen them in tyre fitting bays when they take of the wheel nuts

Typically ypu use an impact driver for loosening and tightening high torque nuts such as wheel nuts or shocks.
