10 Best Cordless Impact Wrenches 2025 in the United States

The DEWALT 20V MAX Cordless Impact Wrench (DCF900B) is a robust tool designed to handle a wide range of fastening tasks, boasting impressive torque capabilities with 1030 ft-lbs of max fastening torque and 1400 ft-lbs of max breakaway torque. This makes it powerful enough for challenging jobs. The tool's 4-mode speed settings and variable speed trigger offer excellent control, making it versatile for different applications.

Additionally, the Precision Wrench control feature helps prevent overtightening and fastener run-off, which adds to its user-friendly design. The integrated LED work light is useful for illuminating dark workspaces, enhancing visibility and accuracy during use. However, the wrench is quite hefty at 7 pounds, which may lead to fatigue during prolonged use. The tool's ergonomic design attempts to balance this weight, but it still might be cumbersome for some users.

Another factor to consider is that the battery is sold separately, which can add to the cost. The DEWALT 20V MAX utilizes a Lithium-Ion battery and features BATTERYGUARD technology to protect against wear and tear. The 1/2-inch anvil size is standard and should fit most common applications. This tool is well-suited for professional tradespeople or serious DIY enthusiasts who need a powerful and versatile impact wrench.

The Milwaukee M18 FUEL 18V Cordless 1-inch Impact Wrench stands out for its impressive power, delivering up to 2,000 ft-lbs of torque, which is excellent for heavy-duty tasks like removing lug nuts and other tough bolts. It comes with two 12.0 Ah batteries, offering long runtime—enough to handle around 120 lug nuts on a single charge—making it reliable for extended use without frequent recharging. The tool features four speed settings that let you adjust power and speed according to the job, adding versatility. At 23.2 pounds, it’s on the heavier side, which is something to consider if you'll be holding it for long periods, but the D-handle design and adjustable side handle help improve grip and control. The 1-inch anvil size is suitable for large fasteners, and the impact wrench also benefits from a patented battery isolation system that reduces vibrations, protecting both the tool and your hands.

Additional features like LED lighting enhance visibility in tight spaces, and the ONE-KEY system allows for tool customization and torque control to prevent over-tightening. The weight may be tiring for some users, and while the price is higher than average, the performance and build quality justify the investment for professionals or serious DIYers needing a powerful and reliable cordless impact wrench.

The DEWALT 20V MAX Cordless Impact Wrench is a highly capable tool designed for heavy-duty fastening tasks. With an impressive max torque of 1200 ft-lbs and breakaway torque of 1750 ft-lbs, it stands out as one of the most powerful options in its category, making it suitable for both professionals and serious DIY enthusiasts. The inclusion of three speed settings and a precision wrench mode adds versatility, enabling users to prevent overtightening and manage various fastening tasks effectively.

One of the key strengths of this impact wrench is its brushless motor, which enhances its efficiency and extends the tool's lifespan. Weighing in at 8.4 pounds, it strikes a balance between being sturdy yet manageable, but the weight might be a consideration for prolonged use or for users who prefer lighter tools.

It's important to note that this model is sold as a bare tool, meaning it does not come with a battery or charger. This could be a drawback for users who are new to cordless tools and do not already own compatible 20V batteries. Potential buyers should also consider their specific needs regarding torque and size; while the 1/2 inch hog ring is standard, those who require different anvil sizes may need to look elsewhere. In terms of ergonomics, the impact wrench is designed for comfort, yet some users might find the grip less ideal for extended heavy use.
