10 Best Highest Torque Impact Wrench 2025 in the United States

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 Ingersoll Rand 2236QTIMAX DXS2 is a powerful air impact wrench delivering an impressive 1,500 ft-lb of torque, making it a strong contender for anyone needing high torque for tough fastening jobs. It features a 1/2" drive with interchangeable options (3/8", 1/2", and 3/4"), adding versatility for different tasks, though these extras are sold separately. Being air-powered, it requires a compressed air source, which is ideal in professional or workshop settings but less convenient for casual or mobile use. Weighing 4.4 pounds and measuring 7.4 inches, it strikes a good balance between power and manageable size, supported by an ergonomic design that aims to reduce user fatigue during prolonged use.

Its titanium hammer case adds durability and resistance to wear, while the patented Direct Greasing System simplifies maintenance. The tool also benefits from a quieter motor design, which is a plus in noisy environments. On the downside, since it is pneumatic, it lacks cordless convenience, and the need to buy additional drive sizes separately could add to the cost. This impact wrench is well suited for professionals or serious DIYers who prioritize torque, durability, and tool longevity in a pneumatic format.

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.
