10 Best Highest Torque Cordless Impact Wrench 2025 in the United States

The DEWALT 20V MAX Cordless Impact Wrench Kit stands out in the category of highest-torque cordless impact wrenches due to its impressive torque capabilities. It boasts 1030 ft-lbs of max fastening torque and 1400 ft-lbs of max breakaway torque, making it suitable for heavy-duty applications. The 4-mode speed settings and variable speed trigger allow for precise control, which is useful in various tasks and helps prevent overtightening and fastener run-off.

Its ergonomic design includes a shock-absorbing battery-to-tool connection, known as the battery guard, reducing wear and tear on the battery during use. Additionally, the on-tool LED work light is a practical feature for working in dimly lit areas. However, the tool is relatively heavy at 11 pounds, which might be cumbersome for prolonged use. The included 20V MAX 5.0 Ah battery offers decent longevity, but the weight could impact user comfort.

Durability is assured with the aluminum and alloy steel construction, and DEWALT's reputation for quality tools is backed by a 3-year limited warranty, 1-year free service contract, and 90-day money-back guarantee. This impact wrench is ideal for professionals or serious DIY enthusiasts looking for high torque and reliability in their tools.

The DEWALT 20V MAX Cordless Impact Wrench (DCF900B) is a strong choice if you need high torque for tough fastening jobs. It delivers 1030 ft-lbs of fastening torque and 1400 ft-lbs of breakaway torque, which is excellent for loosening stubborn bolts. Operating on a 20V battery system, it offers good power and compatibility with other DEWALT tools, though the battery is sold separately, so you’ll need to budget for that. The tool features four speed settings and a variable speed trigger, giving you control for different tasks and helping prevent over-tightening with its Precision Wrench control. This makes it user-friendly for both beginners and experienced users.

Weighing 7 pounds, it’s a bit on the heavier side, so it might feel tiring during extended use, but the build includes a shock-absorbing connection to reduce wear on the battery and improve durability. The compact size (just over 8 inches long) and integrated LED light help when working in tight or dark spaces. The plastic body with powder coating seems sturdy and should hold up well on job sites.

If you prioritize maximum torque combined with customizable speed and good durability, this DEWALT impact wrench is a solid pick that balances power and control effectively.
