10 Best Cordless Impact Wrenches 2025 in the United States

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 (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 Ingersoll Rand W9691-K4E W9000 Series cordless impact wrench is a heavy-duty tool designed for professionals who need powerful and reliable performance. Its standout feature is the strong torque output of 3,000 ft-lbs, making it suitable for tough jobs like automotive or industrial work. Running on a 20-volt battery system with four included lithium-ion batteries, it offers good runtime, capable of handling around 250 bolts per full charge, which means less downtime during busy workdays. The brushless motor and IQV Power Control System provide three speed settings (MAX Power, MID, and Snug), allowing users to adjust power depending on the task, which improves precision and helps prevent overtightening. The 6-inch extended anvil is ideal for reaching deeply recessed fasteners, adding versatility.

This wrench weighs about 42 pounds, which may cause fatigue if used continuously for long periods or in awkward positions. Its size and weight make it less convenient for casual or light users but fit well in a professional setting where durability and power are priorities. The tool is also built tough with an IP56 rating, meaning it's resistant to dust and water spray, and has a durable housing to withstand harsh environments. Noise level is moderate at 95 dB, typical for this type of equipment. The kit includes multiple batteries and a charger, supporting extended use without waiting for recharges.

This impact wrench is well suited for users who need high torque, battery-powered convenience, and rugged build quality, though its weight might be a limitation for those seeking a lighter, more portable option.
