Milwaukee 0779-22 28 Volt Lithium-Ion 1/2" Cordless Impact Wrench
As we’ve come to expect, Milwaukee beats everyone hands down on raw power. This 28 volt unit is so powerful, it could easily be considered a mechanic’s tool. Rated at 325 ft/lbs, this is the most powerful cordless impact on the market. Considering other cordless impacts are rated in inch-pounds, this should give you a pretty good idea of how powerful this really is.
A lot of this tools power has to do with the 28 volt battery, the highest voltage battery put into any cordless impact. One really great thing about this battery system is it provides up to 2 times the run time of 18 volt systems while the impact provides 2450 BPM at 1450 RPM. A top mounted hanger makes it easy to tether this tool when you’re working high overhead.
