Cordless impact wrenches have gotten good enough that they've replaced air guns in a lot of mobile and field work. But battery platforms lock you into an ecosystem, spec-sheet torque numbers are marketing, and the price spread between "fine for lug nuts" and "breaks rusted suspension bolts" is enormous.

These guides sort cordless wrenches by the jobs people actually buy them for — automotive, farm, fleet, and home garage — with honest notes on where a battery gun still can't replace shop air.
