How are these things different from drills? A drill will not stop if it catches on to a nut and will rip the drill out of your hand but how is an impact wrench different?

Especially when they are torquing to 150 ftlb+ How exactly could you hold it wile it was spinning that off?

Do you mean an Air wrench (as in the ones used for wheel nuts) or an impact wrench (as in the type you hit with a hammer to get the nut turning)

I only use impact wrenches primarily to get very tight or nuts / bolts / screws loosened - and these types of wrenches transfer the power (using gears) of the hammer hit to a vast amount of rotational energy in the socket.
