10 Best Compact Impact Wrenches 2025 in the United States

The Milwaukee 2855-20 18V Brushless Cordless 1/2" Impact Wrench is a compact yet powerful tool suitable for various tasks that require high torque. Its POWERSTATE brushless motor provides up to 250 ft./lbs. of nut-busting torque, making it efficient for heavy-duty jobs. The addition of Tri-LEDs enhances visibility in workspaces, reducing shadows and thereby improving accuracy and safety.

The auto shut-off mode is particularly useful for preventing over-tightening, ensuring you don't damage your bolts or work material, while the bolt-removal mode offers better control by reducing RPMs once a bolt is loosened, preventing any potential over-torquing issues. Weighing just 2.4 pounds and measuring 4.9 inches in length, this impact wrench is lightweight and highly portable, which helps reduce user fatigue during prolonged use.

It is cordless, powered by an 18V lithium-ion battery (not included), which means you have the freedom to use it anywhere without worrying about a power outlet. However, this model does not come with a battery, requiring you to purchase it separately, which might be an additional cost to consider. The ergonomic design and compact size make it easy to handle, but for those needing a wrench for extremely tight spaces, it may still be slightly bulky. This impact wrench is ideal for both home improvement enthusiasts and professionals seeking a reliable and efficient tool for medium to heavy-duty tasks.

The DEWALT 20V MAX Cordless Impact Wrench (DCF891B) is a versatile tool designed to handle a wide range of fastening tasks. With a maximum fastening torque of 600 ft-lbs and a breakaway torque of 800 ft-lbs, it offers strong performance for both tightening and loosening bolts. The tool features four-speed settings and a variable speed trigger, allowing you to adjust the power based on the task at hand, which adds to its versatility. Additionally, the precision wrench control helps prevent overtightening and fastener run-off, which is a handy feature for achieving accurate results without damaging materials.

The built-in LED work light is a useful addition, making it easier to work in dark or confined spaces. This makes the tool suitable for mechanics, contractors, and DIY enthusiasts alike. The wrench is compact and lightweight, weighing just 4 pounds, and measures 8.88 inches in length. This ergonomic design ensures that it’s comfortable to use, even in tight spaces.

One of the drawbacks is that the wrench is sold as a bare tool, meaning the battery is not included. This could be an additional expense if you don't already own compatible DEWALT batteries. However, it uses lithium-ion batteries, which are known for their long battery life and reliability. The DEWALT 20V MAX Cordless Impact Wrench comes with a three-year limited warranty, one year of free service, and a 90-day money-back guarantee, offering peace of mind for buyers. While it may not be suitable for those who need a corded model, its cordless nature adds to its convenience and mobility.

The Milwaukee M18 FUEL 3/8" Compact Impact Wrench is a solid choice for those needing a powerful and compact tool. With a torque of 20 foot-pounds, it is suitable for various light to moderate tasks, though it may not be ideal for extremely heavy-duty applications. Weighing in at just 2.79 pounds, it's relatively lightweight and easy to handle, reducing user fatigue during prolonged use. Its compact size, with a length of 4.8 inches, makes it convenient for working in tight spaces.

Ergonomically, the plastic build and design are typical of Milwaukee’s robust and comfortable tools, though some users might prefer a more premium material for durability. This model is battery-operated, using lithium cells, which are known for their long life and quick recharge times. However, it's important to note that this particular package does not include a battery or charger, which must be purchased separately. This could be a drawback for first-time buyers but may not be an issue for those already using Milwaukee tools.

For anyone needing a compact, reliable impact wrench and already invested in the Milwaukee M18 battery system, this tool is highly recommended.
