Which Milwaukee impact wrench fits your job?
The M18 compact 3/8 in model is our first choice for tight automotive access, while the other models suit different drive and torque needs. Check your socket drive size and working clearance before choosing a tool.
Milwaukee M18 FUEL 3/8 Inch Compact Impact Wrench: Best for tight automotive access
- 4.8 in length
- Up to 250 ft-lb nut-busting torque
- 4-mode DRIVE CONTROL
- Tri-LEDs around the anvil
A short body and 3/8 in friction ring suit tight automotive spaces. Four control modes add options for fastening and bolt removal.
Pros
- Compact 4.8 in body
- Tri-LEDs around the anvil
- Auto shut-off mode for hand-tight applications
Cons
- Battery and charger not included
- Requires sockets with a matching 3/8 in drive
The Milwaukee M18 FUEL 3/8 Inch Compact Impact Wrench suits jobs where a longer wrench would be awkward in a crowded work area. Its 4.8 in length and 3/8 in friction ring are the key fit points.
Milwaukee states that it delivers up to 250 ft-lb of nut-busting torque. Its 4 DRIVE CONTROL modes include preset speed and impact levels, plus auto shut-off that applies no more than 20 ft-lb for hand-tight fastening applications.
Tri-LEDs around the anvil light the work area with fewer shadows. Mode 4 also includes bolt removal control, which lowers speed after a bolt loosens to help reduce fastener drops.
Choose this model for compact 3/8 in work and control options in an M18 tool. It is a bare tool, so you'll need a compatible M18 battery and charger.
Milwaukee 2962-20 M18 FUEL 1/2 Inch Mid-Torque Wrench: Best for balanced 1/2 in jobs
- 1/2 in friction ring
- Tri-LED lighting
- Auto shut-off control
- Bolt removal control
A 1/2 in friction ring and mid-torque design suit buyers who want control features for fastening and removal.
Pros
- Quick socket changes with friction ring
- Tri-LEDs reduce shadows
- Bolt removal control slows after loosening
Cons
- Longer than the compact picks
- Tool-only package
The Milwaukee 2962-20 M18 FUEL 1/2 Inch Mid-Torque Wrench suits buyers who want a 1/2 in drive with fastening and removal controls. Its friction ring supports quick socket changes, and tri-LEDs illuminate the work area.
Auto shut-off control applies no more than 35 ft-lb for hand-tight fastening applications. Bolt removal control delivers full torque at first, then slows the tool after the bolt loosens.
This model measures 10 in long, so check clearance around your work. Its length may matter near crowded engine components or other obstructions.
Choose it when your sockets use a 1/2 in drive and you want these control features. Compare it with our guide to 1/2 in vs 3/8 in impact wrenches if you haven't settled on a drive size.
Milwaukee 2767-20 M18 FUEL 1/2 Inch High Torque Wrench: Best for demanding fasteners
- Up to 1,000 ft-lb fastening torque
- Up to 1,400 ft-lb nut-busting torque
- 1/2 in friction ring
- Works with M18 batteries
This high-torque model suits demanding fastening work where its torque output matters more than compact size.
Pros
- High fastening and nut-busting torque
- Friction ring supports one-handed socket changes
- Compatible with M18 batteries
Cons
- Weighs 6 lb
- Battery not included
The Milwaukee 2767-20 M18 FUEL 1/2 Inch High Torque Wrench suits demanding fastening work. Milwaukee states up to 1,000 ft-lb fastening torque and 1,400 ft-lb nut-busting torque from its POWERSTATE brushless motor.
Its 1/2 in friction-ring anvil supports quick, one-handed socket changes. The tool works with M18 batteries, but the battery is not included.
At 6 lb and 9.65 in long, this model is larger and heavier than the compact options. Choose it when its torque output matters more to your task than low weight or tight access.
Its torque figures describe tool output, not the correct tightening torque for every fastener. For a closer look at this model, read our Milwaukee 2767-20 review.
Milwaukee 2855-20 M18 FUEL 1/2 Inch Compact Wrench: Best for compact 1/2 in access
- 4.9 in length
- Brushless motor
- Three LEDs
- Friction ring
The short 4.9 in body pairs a 1/2 in drive with a friction ring, fitting jobs where access is tight and your sockets use that drive size.
Pros
- Compact 4.9 in length
- Three LEDs for work area lighting
- Bolt removal mode slows after loosening
Cons
- Requires sockets with a matching 1/2 in drive
- Uses M18 rather than M12
The Milwaukee 2855-20 M18 FUEL 1/2 Inch Compact Wrench suits tight spaces where your sockets use a 1/2 in drive. It measures 4.9 in long and has a friction ring for socket changes.
Its brushless motor pairs with 3 LEDs for work area lighting. Bolt removal mode slows the tool after the bolt breaks loose.
The tool also includes an automatic shut-off mode. That control does not replace checking a fastener's final torque against the equipment maker's specification.
Choose this model when you want a short M18 wrench with a 1/2 in friction-ring anvil. Its 4.9 in length is close to the 4.8 in M18 compact 3/8 in pick, so drive size is a useful deciding point.

- 1/2 in pin detent

- Compact M18 FUEL design
This compact 1/2 in option uses a pin-detent anvil for buyers who prefer that socket-retention style.
Pros
- Compact 4.9 in body
- Pin-detent anvil
- M18 FUEL model
Cons
- Pin detent may not suit buyers who prefer friction rings
- Uses M18 rather than M12
The Milwaukee 2855P-20 M18 FUEL 1/2 Inch Compact Pin Detent Wrench suits buyers who prefer a pin-detent anvil. At 4.9 in long, it has the same length as the friction-ring 2855-20.
This M18 FUEL model weighs 2.8 lb. Its compact body and 1/2 in drive make it an alternative to the 2855-20 when socket-retention style guides your choice.
Pick it if you want pin-detent socket retention in a short 1/2 in wrench. Our compact impact wrench comparison can help you weigh it against friction-ring options.
Milwaukee M12 FUEL 3/8 Inch Stubby Impact Wrench: Best for an M12 tool setup
- 3/8 in drive
- 4.8 in length
- Up to 550 ft-lb nut-busting torque
The Stubby is a short M12 option for buyers choosing that battery platform and looking for a 3/8 in drive.
Pros
- 4.8 in length
- Up to 550 ft-lb nut-busting torque
- M12 platform
Cons
- Uses a different platform from the M18 picks
- Bare-tool package
The Milwaukee M12 FUEL 3/8 Inch Stubby Impact Wrench suits buyers who want a compact tool on Milwaukee's M12 platform. It measures 4.8 in long, and Milwaukee states up to 550 ft-lb of nut-busting torque.
The short body may suit crowded work areas, provided there's room for the socket and battery too. Its 3/8 in drive needs sockets with a matching drive connection.
Choose this bare tool if an M12 setup is central to your decision. If you already use M18 tools, compare it with the M18 compact 3/8 in pick before adding another battery platform.
How do you choose a Milwaukee impact wrench?
Choose by socket drive size, working clearance and fastening needs. A tool that fits your battery setup and work area can be more useful than a larger model with torque you won't need.
Is a 3/8 in or 1/2 in Milwaukee impact wrench better?
Choose the drive that matches your impact sockets and the work you plan to do. Drive size describes the square socket connection, not the size of the nut or bolt.
The 3/8 in picks here are both 4.8 in long, while the 1/2 in models span compact, mid-torque and high-torque options. Our impact wrench size guide can help you compare those needs.
Should you buy compact, mid-torque or high-torque?
Choose a compact wrench for limited clearance, the 2962-20 for a mid-torque 1/2 in option, or the 2767-20 when its higher torque output fits the job. Compare actual dimensions rather than relying on the tool's class alone.
Avoid choosing only by the largest torque number. Length, weight, anvil style and battery platform also affect whether a wrench fits your tasks.
Does battery platform matter?
Yes, M12 and M18 are different battery platforms. The M12 Stubby is the M12 option here, while the other picks are M18 models.
A tool that matches batteries you already own can help you avoid a second battery setup. The M18 compact 3/8 in wrench, 2962-20, 2767-20 and M12 Stubby are bare-tool or tool-only options.
Confirm the included battery and charger before ordering. Read the complete cordless impact wrench buying guide for more on battery, anvil and control choices.
What should you know before using one on wheels?
An impact wrench can help loosen lug nuts, but use a torque wrench for final tightening to the vehicle maker's specification. The impact wrench's output and auto shut-off limit are not the wheel's target torque.
Use impact-rated sockets, start wheel nuts by hand and follow the vehicle maker's lifting and wheel-installation instructions. Read our guide on removing lug nuts with an impact wrench and our explainer on impact wrench vs torque wrench for wheels before working on a vehicle.
Which Milwaukee impact wrench should you choose?
Choose the Milwaukee M18 FUEL 3/8 Inch Compact Impact Wrench for a short 3/8 in tool with 4 control modes. Pick the 2962-20 for a mid-torque 1/2 in wrench, the 2767-20 for its higher torque output, or the M12 Stubby to fit an M12 setup.
For tight spaces that call for a 1/2 in drive, compare the friction-ring 2855-20 with the pin-detent 2855P-20. If your choice comes down to Milwaukee or DeWalt, see our brand comparison of DeWalt vs Milwaukee impact wrenches.

Frequently asked questions
Which Milwaukee impact wrench is best for car repairs?
The Milwaukee M18 FUEL 3/8 Inch Compact Impact Wrench is our top pick for many automotive tasks because it has a 4.8 in body and 4-mode control. If your sockets use a 1/2 in drive, consider the 2962-20 mid-torque or compact 2855-20.
Use a torque wrench for final wheel fastener tightening.
Should I choose a Milwaukee M12 or M18 impact wrench?
Choose M12 if you already use that platform and want the Stubby's 3/8 in drive and 4.8 in length. Choose M18 if it matches your battery setup or you want one of the 1/2 in options here.
Our M12 vs M18 impact wrench guide compares the platform choice.
What is the difference between a friction ring and pin detent?
A friction ring supports quick socket changes, while a pin detent retains a socket with a pin. The compact 2855-20 uses a friction ring, and the 2855P-20 uses a pin detent.
Choose the attachment style you prefer, and read our friction ring vs pin detent guide for more.
Can an impact wrench tighten lug nuts?
An impact wrench can turn lug nuts, but it does not replace a torque wrench for final tightening to the vehicle maker's specification. Start each nut by hand to avoid cross-threading, and follow the vehicle's wheel-installation procedure.
Read our guide to impact wrench torque for lug nuts before working on wheels.
