10 Best Highest Torque Impact Wrench 2026 in the United States

The DEWALT 20V MAX Cordless Impact Wrench (DCF961B) is a robust tool designed for heavy-duty applications. It boasts an impressive 1200 ft-lbs of max fastening torque and 1750 ft-lbs of max breakaway torque, making it ideal for tasks like working on large-sized pipe flanges and wheel lugs where high torque is essential. The 1/2 inch drive size is standard and versatile, fitting many common sockets and attachments.

Power is supplied by a 20V lithium battery, though it's important to note that batteries are not included with the bare tool, which means additional costs for users who don't already own compatible batteries. The impact wrench offers three speed settings and a precision wrench mode to help prevent overtightening, adding to its usability and control in diverse situations. It also features an LED work light to improve visibility in dark or confined spaces.

Weighing 8.4 pounds, it might affect ergonomics during prolonged use. However, its powder-coated finish promises durability and long-term use. This DEWALT impact wrench is suitable for users needing high torque and reliability, though the absence of included batteries and its relatively high weight may be drawbacks for some.

The Milwaukee 2767-20 M18 FUEL High Torque 1/2" Impact Wrench is a solid choice if you're looking for powerful performance. It delivers up to 1000 foot-pounds of torque, which is excellent for heavy-duty tasks like automotive repair or industrial work. The 1/2-inch drive size is standard and versatile, fitting most impact sockets you'd need. Being battery-powered, it offers good mobility without the hassle of cords, and although batteries aren’t included with this bare tool, it runs on Milwaukee’s M18 battery system, known for reliable power and decent runtime.

Weighing 6 pounds and measuring about 9.65 inches long, it strikes a fair balance between power and handling, though it’s a bit on the heavier side compared to some competitors, which might cause fatigue during extended use. The rubber overmold finish improves grip and comfort, making it easier to hold securely. Milwaukee is known for durable tools, and this model appears rugged enough for frequent use in tough conditions.

On the downside, since it’s a bare tool, you’ll need to invest separately in batteries and a charger if you don’t already have them. Also, it’s not the lightest option out there, so if you prioritize portability and lighter weight over maximum torque, you might find it a bit bulky. For anyone needing a high-torque impact wrench that can handle demanding jobs with solid build quality, the Milwaukee 2767-20 is a strong contender.

The Milwaukee M18 FUEL 18V brushless impact wrench stands out with an impressive torque of up to 2,000 ft-lbs, making it one of the most powerful cordless models available. Its 1-inch drive size is ideal for heavy-duty tasks, especially those involving large lug nuts. Powered by two high-capacity 12.0 Ah lithium-ion batteries, it offers excellent runtime, capable of handling up to 120 lug nuts on a single charge, which is great for demanding jobs without frequent recharging.

The tool’s brushless motor and REDLINK Plus intelligence protect it from overload and overheating, increasing durability and reliability. Features like the ONE-KEY system allow users to customize torque settings to avoid overtightening, adding precision and control that’s useful for professionals who need consistency. The adjustable D-handle and removable side handle improve ergonomics, but at 23.2 pounds, it’s relatively heavy, so it might feel bulky during extended use. The built-in LEDs help illuminate dark work areas, enhancing usability.

While the price and weight might be a consideration, this impact wrench is well-suited for mechanics, heavy equipment maintenance, and anyone needing powerful, cordless torque with smart control features.
