10 Best Cordless Impact Wrenches 2025 in the United States

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 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 2967-21B M18 FUEL 18V Lithium-Ion Brushless Cordless 1/2 inch Impact Wrench stands out for its impressive torque of 1,500 foot-pounds, making it suitable for heavy-duty tasks. With an 18V battery and a 5.0 Ah capacity, it offers substantial power and longer run times, which is beneficial for prolonged use. The brushless motor contributes to its efficiency and durability, ensuring better performance and a longer lifespan compared to brushed motors.

Additionally, the friction ring feature makes it easy to change sockets quickly, enhancing convenience during use. The impact wrench operates at a maximum speed of 2,000 RPM, which, combined with its high impact rate, ensures efficient and fast completion of tasks. However, at 11.16 pounds, it is relatively heavy, which might cause fatigue during extended use. Ergonomically, the design is somewhat bulky, which could be less comfortable for users with smaller hands or those who need to work in tight spaces.

The included components, such as one 5.0 Ah battery and a bag, are useful additions, though some users might find the absence of extra batteries a drawback, especially for continuous work. This impact wrench is best suited for professional mechanics or serious DIY enthusiasts who require a powerful, reliable tool for demanding applications.
