Does it come with a battery and charger?

No. It is a bare tool, so you need an M12 REDLITHIUM battery and an M12 charger, sold separately.

How much torque does it make?

Up to 550 ft-lbs of nut-busting torque. In auto shut-off mode it applies no more than about 15 ft-lbs.

What is the difference between the four modes?

Mode 1 runs 0-930 RPM, Mode 2 0-2,100 RPM, Mode 3 0-3,000 RPM, and Mode 4 0-1,300 RPM for bolt removal. Auto shut-off is part of the DRIVE CONTROL settings.

What size sockets does it take?

It has a 1/2-inch anvil with a friction ring, so it takes standard 1/2-inch drive impact sockets.

Is it strong enough for lug nuts?

For most passenger car and light truck lug nuts, yes. For heavily torqued or rusted fasteners, a full-size high-torque wrench is the safer choice.

Which batteries work with it?

It is compatible with all M12 REDLITHIUM batteries and chargers. Higher-capacity packs give longer runtime.

Price facts

What reviewers say

Owners rate the Stubby highly for its size-to-power ratio, calling it the wrench they reach for first on automotive jobs. The common complaints are that it ships without a battery and that it cannot replace a full-size wrench for the heaviest work.

What people mention

SizePraisedOwners say the stubby body gets into engine bays and wheel wells that a full-size wrench cannot reach.
TorquePraisedReviewers are impressed by the nut-busting power for a 12V tool, enough for most lug nuts and suspension bolts.
Battery platformMixedPeople like that it uses existing M12 packs, but many note the bare tool needs batteries and a charger bought separately.
Mode controlPraisedThe four-mode DRIVE CONTROL, especially auto shut-off, is called handy for small fasteners and bolt removal.
LightingPraisedThe tri-LED setup is described as bright with few shadows on the work area.
Power ceilingCriticisedSome owners say it cannot match an 18V or 20V wrench on the heaviest fasteners and is best as a companion tool.

About the Milwaukee M12 FUEL (STUBBY) 1/2 Inch Impact Wrench (Bare Tool)

The Milwaukee M12 FUEL stubby impact wrench has a 1/2 inch drive and is sold as a bare tool. It is compact and light, and it delivers up to 550 ft-lbs of nut-busting torque.

A 4-mode DRIVE CONTROL system sets output speed and power. The modes include an auto shut-off mode and a bolt-removal mode. Auto shut-off applies no more than 15 ft-lbs of torque, which prevents over-tightening. Three LEDs light the work area with less shadow.

A Battery Isolation System secures the battery connection and reduces the vibration passed to the pack. A friction ring retains sockets, which cuts downtime when accessories are changed often. The tool works with all M12 REDLITHIUM batteries and chargers.
