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 Makita XWT16Z 18V LXT Brushless Cordless 3/8 Impact Wrench is a compact and powerful tool. It offers impressive torque levels, with 220 ft.lbs. for fastening and 370 ft.lbs. for nut-busting, making it suitable for heavy-duty tasks. The 4-speed power selection switch allows for versatile use, letting you adjust the speed and impact per minute (IPM) to match various applications, ensuring precise control. This feature is particularly useful in professional settings where different tasks require different levels of power.

This tool is sold as 'Tool Only,' so you'll need to purchase the battery separately. This could be a downside for those looking for an all-in-one package. The compact design, at only 5-1/2 inches long, makes it easy to handle and maneuver, reducing user fatigue. Additionally, the ergonomic design further enhances user comfort, making it a great choice for extended use.

The durability of this impact wrench is high, with a robust metal construction that can withstand tough job site conditions. Another notable feature is the 3 forward and 3 reverse Auto-Stop modes, which increase efficiency by stopping the rotation at the right moment, preventing over-tightening or loosening. This impact wrench is powerful, versatile, and durable but requires a separate battery purchase, which could be a consideration for budget-conscious buyers.
