![]() ![]() ![]() ![]() Unlike cordless drill/drivers and impact drivers, which excel at drilling holes and driving screws, the impact wrench is specially designed for tightening and loosening various hex-head bolts, nuts and lag screws. The difference with an impact wrench it that it uses both rotational force (torque) and short-burst concussive blows or impacts which are measured in milliseconds, to deliver high power in a small tool. It’s impossible to overstate the impact that cordless power tools have had in the construction, mechanical and engineering industries, and the cordless impact wrench is no exception.
