Now this Arrangement is something that I use at work often.. has tons options.. but more and more I find I'm using it in the garage.. I know there are fancy impacts that are cordless but this is what I have.. everything from changing wheel screws to zipping off the valve covers. I will even install my lug nuts.. and finish the job with a torque wrench of course. the adapters are available in quarter inch 3/8 and 1/2 inch..
