Our take on the Milwaukee M12 FUEL Stubby 3/8" Impact Wrench

The Milwaukee M12 FUEL Stubby 3/8" Impact Wrench is a compact cordless impact wrench built on Milwaukee's 12V M12 FUEL brushless platform. It delivers up to 550 ft-lb of fastening torque in a body that weighs about 2.2 lb, so it fits where full-size 18V impact wrenches will not. The 3/8-inch anvil drive covers lug nuts on most cars and light trucks plus general assembly work. Its best new price was $155.00 at eBay as of November 3, 2026, with three stores listing it new; that is a low point for this tool, which typically sells for well above that.

Questions and answers

Is the M12 Stubby strong enough for lug nuts?
Yes for most passenger cars and light SUVs, where lug nuts are torqued around 80 to 100 ft-lb. It has 550 ft-lb of breakaway torque, but heavily torqued truck wheels or rusted nuts may still need a breaker bar.
Does it come with a battery and charger?
Most listings at this price are bare tool only, so check the listing before buying. Budget for an M12 battery and charger if you do not already own them.
How does it compare to the full-size M18 impact wrench?
The M12 Stubby is far smaller and lighter and is easier to fit into tight spaces. The M18 High Torque models make more torque and run longer, but they are bigger and heavier.
What size sockets does it use?
It has a 3/8-inch anvil drive, so it takes standard 3/8-inch impact sockets. Use impact-rated sockets, not chrome hand sockets.
When is the best time to buy it?
Prices swing with Milwaukee promotions and holiday sales. The $155.00 at eBay as of November 3, 2026 is well below typical pricing, so it is a strong buy at that level.
Is it worth it over the older non-FUEL M12 impact?
Yes. The FUEL brushless version makes substantially more torque and adds drive control modes, which matters for lug nuts and stubborn fasteners.

At Walmart, for $168.99, as of our latest check.
