Milwaukee is one of the best-known names in cordless power tools, and its M18 line is the brand’s 18-volt system, built around shared batteries that slide into many different tools. An impact driver is one of the most popular tools in that system. It looks like a small drill, but instead of a normal chuck it has a 1/4 inch hex socket that grabs screwdriver bits, and when the screw gets hard to turn it adds rapid rotating blows to drive it home. That makes it excellent for long screws, deck boards and lag bolts, while a regular drill is still the better tool for drilling clean holes.
The six Milwaukee products below differ mainly in power, size and what comes in the box: two high-torque Fuel-style drivers, two compact brushless drivers, an older brushed driver sold as a bare tool, and a two-tool combo that pairs a hammer drill with a compact impact driver.

Milwaukee Electric M18 Fuel 1/4 Hex Impact Driver for Maximum Speed
Milwaukee
Milwaukee Electric – M18 Compact BRUSHLESS 1/4 INCH HEX 3-Speed Impact
Price and specifications are read from the Amazon product page and can change.
Milwaukee Electric
Best for: Working in tight spaces
Pros
- Just 4.4 in long, 1.7 lbs
- Brushless motor
- All-metal gearcase
- 5-year tool warranty
Cons
- Bare tool, no battery
- Lower torque than Fuel models
Best for: Pros wanting top speed and torque
Pros
- 2000 in-lbs of torque
- 3900 rpm top speed
- 4-Mode Drive Control
- Tri-LED lighting
Cons
- Speed count in listing is unclear
The Milwaukee Electric M18 Fuel 1/4″ Hex Impact Driver sits at the top of this list for raw numbers. The listing gives 2000 in-lbs of torque (in-lbs, or inch-pounds, measure twisting force; higher means it can drive bigger fasteners) and a top speed of 3900 rpm, and Milwaukee describes it as having the fastest driving speed of any impact driver without sacrificing power or control.
Control matters as much as power on a tool this strong. The listing mentions smooth trigger acceleration so small screws do not strip or damage the material, plus 4-Mode Drive Control, which lets you choose between gentler and more aggressive settings. Tri-LED lighting brightens the work area. The spec sheet lists 18 speeds, which does not match the four modes named in the features, so treat the drive modes as the reliable figure. The listing does not specify whether a battery or charger is included.
This model suits contractors, serious DIYers and anyone building decks or framing who wants the most driving power in the group. A first-time homeowner hanging shelves will likely find it more tool than they need, and the compact models below are lighter to hold.
Milwaukee Electric M18 Compact Brushless 3-Speed Impact for Tight Spaces
The Milwaukee Electric M18 Compact Brushless 1/4 Inch Hex 3-Speed Impact, model 3651-20 in the description, is built for access. The listing gives a length of 4.4 inches, a width of 2.1 inches and a weight of 1.7 lbs for the tool alone. A brushless motor, which uses electronics instead of wearing carbon brushes, powers it to 3600 rpm and 1700 in-lbs of peak torque.
It includes 3-Mode Drive Control, an all-metal gearcase and gears, and a 5-year tool warranty. It is sold as a bare tool, so you need an M18 battery and charger, which the listing confirms are compatible.
This is a smart pick if you already own M18 batteries and want something that fits inside cabinets, between studs or under sinks. If you are starting from scratch without any batteries, the 2850-21P kit or the 2697-22 combo will save you a separate purchase.

Milwaukee 2850-21P M18 Brushless Lithium-Ion Compact
Best for: First-time owners wanting a complete kit
Pros
- Battery, charger and bag included
- Brushless motor
- REDLINK overload protection
Cons
- Small 2.0Ah battery
- 1600 in-lbs, below Fuel models
The Milwaukee 2850-21P M18 Brushless Lithium-Ion Compact 1/4 in. Hex Impact Driver Kit is the ready-to-use option among the single drivers. The box includes the 2850-20 brushless impact driver, one M18 REDLITHIUM 2.0Ah battery, an M18-M12 multi-voltage charger and a tool bag, so a new owner can start driving screws the day it arrives.
The listing gives 1600 in-lbs of torque, 3200 rpm and a length of 5.1 inches. Milwaukee describes the compact design as well balanced for overhead work and tight spaces. REDLINK intelligence provides overload protection and monitors temperature to protect the tool and battery. The 2.0Ah battery is on the small side, so heavy users may want a second battery.
This is a strong gift for a new homeowner, and a friendly first cordless tool for anyone doing furniture assembly, fence repairs or light decking. If you also need to drill holes, look at our m18 drill and impact kit guide or the 2697-22 combo below.
Milwaukee 2656-20 M18 18V 1/4 Inch Impact Driver for Existing Battery Owners
Milwaukee
Milwaukee 2656-20 M18 18V 1/4 Inch Lithium Ion Hex Impact Driver with 1,500 Inch Pounds of Torque and LED Lighting Array (Battery Not Included, Power Tool Only)
Price and specifications are read from the Amazon product page and can change.
Milwaukee 2656-20 M18 18V 1 4
Best for: Owners with M18 batteries already
Pros
- LED light below chuck
- Textured rubber grip
- Works with many M18 batteries
Cons
- Brushed motor
- Battery and charger not included
The Milwaukee 2656-20 M18 18V 1 4 Inch Lithium Ion Hex Impact Driver is the older, simpler model in this lineup. Its description states that it does not have a brushless motor, and the listing gives 1500 in-lbs of torque, up to 2750 rpm and up to 3450 impacts per minute through a variable-speed trigger.
Practical touches include an LED light just below the quick-connect chuck and a textured rubber grip for secure handling in slippery conditions. REDLINK technology lets the tool and battery communicate to reduce overheating. The listing names compatible batteries including the 48-11-1860, 48-11-1850, 48-11-1828, 48-11-1815, 48-11-1840 and 48-11-1820. The battery and charger are not included.
This model suits someone who already has M18 batteries and needs a dependable second driver for occasional jobs. Anyone wanting more runtime or a smaller tool should step up to one of the brushless models above.
Milwaukee 2697-22 M18 Combo Kit for a Drill and Driver Together
Best for: Beginners needing drill plus driver
Pros
- Hammer drill and impact driver
- Two XC batteries included
- Charger and contractor bag
Cons
- Heaviest kit at 10.9 lbs
- Listing specs mix both tools
The Milwaukee 2697-22 M18 18-Volt Lithium-Ion Cordless Hammer Drill/Impact Driver XC Combo Kit is the only two-tool option here. It includes a 1/2″ hammer drill driver, a 1/4″ hex compact impact driver, two M18 REDLITHIUM XC extended capacity batteries, an M18 and M12 multi-voltage charger and a contractor bag. The listing names a 5-year limited warranty, 4Ah battery capacity and a one-hour charge time.
A few listing figures need care. The spec sheet lists 20 volts even though the batteries are M18, and it gives 500 in-lbs of torque and 1800 rpm without saying which of the two tools those numbers describe, so we would not use them to compare against the single drivers. The kit weighs 10.9 pounds in total.
For a first-time buyer or a gift-giver who is unsure whether someone needs a drill or an impact driver, this combo answers the question by including both. The hammer drill handles holes and masonry work, while the impact driver handles long screws. Our milwaukee 18v drill brushless guide covers standalone drills if you only need the drilling side.
Milwaukee 2953-20 18V Cordless 1/4″ Hex Impact Driver for Power in a Small Body
Best for: Upgraders who own M18 batteries
Pros
- 2000 in-lbs, 3900 rpm
- One-handed bit insertion
- Metal belt clip
- 47 in long
Cons
- Tool only
The Milwaukee 2953-20 18V Cordless 1 4″ Hex Impact Driver pairs top-tier numbers with a short body. The listing gives up to 2000 in-lbs of torque and 3900 rpm, Tri-LED lights, 4-mode drive control, single-handed bit insertion and an all-metal belt clip, in a tool 4.47 inches long weighing 2.2 lbs.
Its headline figures match the Milwaukee Electric M18 Fuel listing at the top of this article, and this listing adds useful details such as the length, weight and belt clip. It is sold as a tool only, so you need your own M18 battery and charger.
Choose it if you already own M18 batteries and want the most power in a compact package. If you need a battery included, the 2850-21P kit is the easier starting point.
How to Choose the Right Milwaukee M18 Impact Driver
Impact driver or drill. An impact driver drives screws and bolts with bursts of force; a drill makes holes and handles light screw driving with a clutch. If the person you are shopping for has neither, the 2697-22 combo covers both jobs.
Check whether a battery is included. The 2656-20, 2953-20 and the compact 3-speed model are bare tools. The 2850-21P and 2697-22 kits include batteries and a charger. Bare tools only make sense for someone who already owns M18 batteries.
Match torque to the work. For furniture, shelves and general household screws, 1500 to 1700 in-lbs is plenty. For decks, framing and lag bolts, the 2000 in-lbs models offer more headroom.
Consider size and weight. The compact 3-speed model, at 4.4 inches and 1.7 lbs, is the easiest to fit into tight spots. For more compact options across the brand, see our milwaukee compact drill guide.
FAQ
Which Milwaukee impact driver should I buy as a first tool?
If you own no M18 batteries, the 2850-21P kit or the 2697-22 combo, since both include batteries and a charger. The combo adds a hammer drill for making holes.
What is the difference between an impact driver and a drill?
A drill spins steadily and has a chuck for round drill bits. An impact driver uses a 1/4 inch hex socket and adds rapid rotational blows under load, which helps drive long screws without straining your wrist.
What does brushless mean on these tools?
A brushless motor uses electronics instead of carbon brushes to switch the current. The 2850-21P listing says its brushless motor delivers more runtime and longer life. The 2656-20 is described as not brushless.
Do these impact drivers work with any M18 battery?
The compact 3-speed model lists compatibility with Milwaukee M18 batteries and chargers, and the 2656-20 names six specific M18 battery models. The other listings are built around the M18 platform as well.
What does drive control or mode control do?
Drive modes limit speed and force so you can drive small screws gently and switch to full power for large fasteners. The Fuel and 2953-20 listings name four modes; the compact 3-speed model names three.
