10 Best Cordless Impact Wrenches 2026 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 Ingersoll Rand W9491-K4E cordless impact wrench is a powerful tool designed for heavy-duty jobs requiring strong torque. It delivers an impressive 2,600 ft-lbs of torque for loosening large bolts and 2,200 ft-lbs for tightening, making it suitable for professional mechanics or serious hobbyists. It runs on a 20V battery system and comes with four 5.0Ah lithium-ion batteries, allowing longer work periods without frequent charging. The tool can handle about 250 bolts per charge, which is convenient for extended tasks.

This wrench features a fixed square anvil and a friction ring-thru-hole retainer to securely hold sockets. The 360-degree adjustable D handle enhances control and comfort during use, which is important given the tool’s weight of 24.3 pounds — making it less ideal for prolonged overhead work or highly mobile tasks. The brushless motor and IQV Power Control System provide good efficiency and torque control. Its IP56 rating ensures resistance to dust and water spray, useful for outdoor or tough environment work, and it has a durable, chemical-resistant housing.

The kit includes the wrench, four batteries, and a charger for added convenience. With a sound level of 94 dB, hearing protection is advisable during extended use. This cordless impact wrench is strong, reliable, and built for demanding jobs. It is a solid choice if you prioritize power and runtime over lightness and compactness, though its heavier weight might be tiring during long or repetitive tasks.

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.
