10 Best Cordless Impact Wrenches 2026 in the United States

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.

The Milwaukee 2967-20 M18 FUEL™ ½" High Torque Impact Wrench stands out in the cordless impact wrench category, particularly for those seeking high torque and versatile performance. It boasts an impressive brushless motor that can deliver up to 1,100 ft-lbs of fastening torque and an even more remarkable 1,600 ft-lbs of nut-busting torque. This power makes it ideal for heavy-duty applications like automotive work or construction projects where tough fasteners are common.

One of its key features is the AUTO SHUT-OFF control, which limits the torque to 50 ft-lbs for hand-tight fastening. This is a significant advantage for preventing overtightening, especially when working on delicate components. Additionally, the Bolt Removal Control in Mode 4 allows users to engage full torque initially and then reduce RPMs, which helps in preventing fasteners from dropping, a valuable feature for maintaining efficiency.

Weighing in at 2.7 kilograms (about 5.94 pounds) and measuring 7.6 inches in length, this wrench is relatively lightweight and compact. This ergonomic design makes it manageable and comfortable to use over extended periods, reducing user fatigue. However, it’s important to note that this is a tool-only unit, meaning it does not come with batteries or a charger, which may be a drawback for users who are not already invested in the Milwaukee M18 battery system. The lack of included batteries can increase the initial investment if you're starting from scratch.

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.
