Our take on the Milwaukee M18 FUEL 1/2 in Impact Wrench 2864-20

The Milwaukee M18 FUEL 2864-20 is a cordless high-torque impact wrench sold as a bare tool, meaning no battery or charger is included. Milwaukee rates it at 1,200 ft-lbs of fastening torque and 1,500 ft-lbs of nut-busting torque, with an 8.59-inch body that Milwaukee calls the most compact in its high-torque class. It runs on the M18 battery platform and adds ONE-KEY tool tracking and up to four saved drive profiles. No current price was provided for this listing, so compare the bare-tool price against the M18 battery and charger you would need to add.

Questions and answers

Is the 2864-20 worth it over the older high-torque model?
Yes if you want the shorter body and ONE-KEY profiles. The 2864-20 is rated at 1,200 ft-lbs fastening and 1,500 ft-lbs nut-busting in an 8.59-inch package, which is easier to fit into tight spots than older, longer high-torque wrenches.
Does it come with a battery and charger?
No. The 2864-20 is a bare tool. You need a Milwaukee M18 battery and an M18 charger, sold separately, before the wrench will run.
What size sockets does it take?
It uses 1/2-inch drive sockets, which is the most common size for automotive and general mechanic work. The friction ring with thru-hole holds the socket and lets you push it off quickly.
How does it compare with the 3/4-inch version?
The 3/4-inch M18 high-torque model takes larger sockets and is aimed at heavy truck and equipment work. The 1/2-inch 2864-20 covers most auto and light-truck fasteners and is the more versatile everyday choice.
When is it cheapest?
Bare-tool prices drop most during Milwaukee promotions and holiday tool sales, and bundled kits with batteries can beat buying the tool and battery separately. Track the price history before buying.
