I have been looking for a cordless ratchet for automotive repair use. I don't have space for a compressor and air tools. I already have an electric impact wrench but would like something to break nuts and bolts in tight spaces. I was looking at cordless ratchets, like those made by SnapOn and Ingersoll Rand. I then came across these right angle impact drivers. Does anyone here use the Rigid R82233 for this purpose? I am thinking that, if it is up to the task, it is better than a cordless ratchet as the impact action will prevent any kickback and therefore no busted knuckles. I also found the Makita BTL063 which looks like a superior unit, but also a much higher pricetag. The Makita uses 18v Li-Ion batteries and has a 3/8" square drive head. With the Rigid I will need an adapter for my sockets and it uses a Ni-Cad 12v battery system. I would like to hear from anyone here that uses one of these right angle impacts for automotive repair as to how it does. Is it strong enough to break most nuts and bolts free? Is it small enough to get into most spaces? Does the head on the Rigid move like the Makita does? How is the battery life? Any likes or dislike in general? How does it compare to an air ratchet? Any and all comments, opinions, and suggestions are welcome and appreciated.
