10 Best Electric Impact Wrenches 2025 in the United States

The DEWALT 20V MAX Cordless Impact Wrench (model DCF900B) is a powerful and versatile tool designed for a range of fastening tasks. It delivers strong torque—1030 ft-lbs for fastening and up to 1400 ft-lbs for loosening stubborn bolts—which means it can handle tough jobs with ease. The 1/2-inch drive size is standard and works well with most sockets, making it suitable for automotive work, construction, and general repair projects. You can adjust its speed through four different settings and a variable speed trigger, giving you good control to avoid overtightening or stripping fasteners. This level of control is enhanced by the Precision Wrench feature, which helps prevent damage to your workpieces.

Weighing 7 pounds, it’s on the heavier side but still manageable for most users, especially considering the power it offers. Being cordless and powered by a 20V lithium-ion battery (sold separately), it provides mobility without being tied to a cord, though battery life will vary depending on usage and the battery you choose. The tool also includes a bright LED light to help you see in darker workspaces and has a shock-absorbing battery connection to protect the battery and tool during use.

Since the battery is not included, additional investment is needed to get started, and the weight might be a bit tiring during extended use. The plastic casing is durable but not metal, which might affect long-term ruggedness in very harsh conditions. For anyone looking for a reliable cordless impact wrench with strong torque, adjustable speed, and useful features like precision control and lighting, this DEWALT model represents a solid choice, especially if you already use or plan to invest in DEWALT 20V batteries.

The DEWALT 20V MAX Cordless Impact Wrench Kit is a powerful tool suitable for a variety of fastening applications, thanks to its impressive torque values: 1030 ft-lbs max fastening torque and 1400 ft-lbs max breakaway torque. The 4-mode speed settings and variable speed trigger provide excellent user control, making it versatile for different tasks. This model also includes a precision wrench control feature to help prevent overtightening and fastener run-off, which is a significant advantage for precise work.

The built-in LED work light is a practical addition, illuminating dark workspaces and enhancing usability in low-light conditions. The product is relatively heavy, weighing 11 pounds, which might be cumbersome for prolonged use. However, the ergonomic design, aluminum, and alloy steel materials contribute to its durability. The tool is battery-powered, with a 20V MAX 5.0 Ah lithium-ion battery included, ensuring a good balance between power and battery life. The battery guard feature helps reduce wear and tear on the battery, promoting longevity.

Despite the high initial cost, the added value of a 3-year limited warranty, 1-year free service contract, and 90-day money-back guarantee provides peace of mind. This impact wrench is ideal for both professional mechanics and serious DIY enthusiasts who need a reliable, high-performance tool. However, its weight could be a potential drawback for those needing to use it for extended periods.

The Milwaukee 2967-20 M18 FUEL™ 1/2" High Torque Impact Wrench is a robust tool designed for demanding tasks. One of its standout features is its impressive torque capabilities, delivering up to 1,100 ft-lbs of fastening torque and 1,600 ft-lbs of nut-busting torque, making it suitable for heavy-duty applications. This is further enhanced by its brushless motor, which ensures durability and efficiency. The AUTO SHUT-OFF control is a thoughtful addition, preventing overtightening by capping the torque at 50 ft-lbs for hand-tightening tasks. Additionally, the Bolt Removal Control in Mode 4 is particularly useful as it reduces RPMs once a bolt is loosened, helping to prevent fastener drops.

At 2.7 kilograms (5.94 pounds), it is on the heavier side, which might be a consideration for prolonged use. Another point to note is that it is sold as tool-only, so batteries need to be purchased separately. Ergonomically, while the weight could be a downside, the compact length of 7.6 inches may offer better maneuverability in tight spaces.

Its battery operation mode requires an 18-volt power source. This impact wrench is a powerful and reliable choice for those needing high torque and advanced control features, although users should be prepared for its weight and the need to purchase separate batteries.
