10 Best Cordless 3 8 Impact Wrench 2026 in the United States

The Milwaukee M18 FUEL 3/8" Compact Impact Wrench with Friction Ring is a bare tool, meaning it does not come with a battery or charger. This tool is designed to be compact and lightweight, weighing only 2.79 pounds, making it easy to handle and reducing user fatigue. The torque capability is 20 foot-pounds, which should suffice for most light to medium-duty applications but might be insufficient for heavier tasks.

Users should be aware that they need to have or purchase an M18 battery separately, as it is not included with the tool. The product’s speed and performance are positively regarded. The ergonomics of the tool are well-regarded, as it is designed to fit comfortably in hand, which helps in prolonged use.

Durability is another strong point, with the tool being made from sturdy plastic and having a powder-coated finish for added protection. However, the lack of included battery and charger adds to the cost, which might be a consideration for those looking for a more budget-friendly option. Additionally, the tool’s compact size might limit its performance in more demanding, heavy-duty applications.

The DEWALT 20V MAX Impact Wrench Combo Kit is a robust choice for both DIY enthusiasts and professionals looking for powerful cordless tools. It includes two impact wrenches: the DCF894 (1/2-inch) and the DCF890 (3/8-inch), making it versatile for various tasks. One of the standout features is the impressive torque: the DCF894 offers up to 330 ft-lbs of max fastening torque and 600 ft-lbs of breakaway torque. This means it can easily handle tough jobs, making it an excellent option for automotive work or heavy-duty applications.

In terms of weight, the DCF894 is relatively lightweight at just 3.48 lbs, which is great for maneuverability, especially in tight spaces. The compact design of the DCF890, weighing only 2 lbs and measuring 5.5 inches in head length, enhances its usability.

Battery life is another strong point, as it comes with a 5Ah lithium-ion battery, which can power both tools effectively, allowing for extended working periods before needing a recharge. The inclusion of an 8 Amp fast charger further reduces downtime. The build quality is solid, but as with any power tool, it’s essential to handle it with care to maintain its durability over time. This combo kit offers a great combination of power, convenience, and user-friendly design, making it an excellent investment for those who need reliable cordless impact wrenches.

The ergonomic design enhances grip, making it easier to handle during prolonged tasks.

However, there are a few drawbacks to consider. While the torque rating is excellent, some users might find the weight slightly cumbersome for overhead or intricate tasks, especially those who require maximum mobility. Additionally, the batteries are not included in the package, which could lead to extra costs if you don't already own compatible batteries.

This impact wrench kit is best suited for individuals who need reliable power tools for automotive work, home repairs, or professional projects. If you're looking for a strong cordless impact wrench that performs well in demanding situations and can handle various tasks, this Milwaukee kit is worth considering.
