Milwaukee 1/2" SAE and Metric 6 Point Impact Socket Set

If you’re running a high-torque 1/2" impact, this is the socket set I’d pair with it. You get a huge range of both SAE and metric sizes, including standard and deep sockets, so it covers everything from lug nuts to heavier automotive and mechanical work.
 
The sockets are impact-rated and come organized in Milwaukee PACKOUT cases, which makes the whole set easy to store, transport, and keep together. I especially like this set paired with the Milwaukee M18 FUEL 1/2" High Torque Impact—it gives you a seriously capable cordless setup without having to piece together a bunch of individual socket sets.
