I was considering the purchase of a 1/2" electric impact wrench. The first application is to change out an anode rod for an electric water heater.
I was looking at some online, and the torque given in the specs between battery powered and wired versions is very close. The battery power specs claimed for a particular model said 4800 in-lb)] vs the wired version with 4140 in-lb.
I already have the battery that would fit the battery powered tool. Would either work just as well? Am I missing something (other than how long you can use it before the battery is drained)?
I also have a 1/4" impact driver with 1400 in-lb, would it work OK for this job?
I ask because I was reading in a Family Handyman magazine that you often need an impact driver to break the bolt loose. I haven't tried it yet with hand tools.
