10 Best Half Inch Cordless Impact 2025 in the United States

The Milwaukee 2767-20 M18 FUEL is a powerful half-inch cordless impact wrench designed for users needing high torque. It delivers an impressive 1000 foot-pounds of torque, making it suitable for tough jobs like automotive repair or heavy equipment maintenance. Weighing 6 pounds, it is on the heavier side, but this helps provide stability during use. The tool features a rubber overmold finish, which improves grip and adds some shock absorption, contributing to user comfort and durability. Its length of around 9.65 inches makes it compact enough to reach tight spaces.

Being part of Milwaukee's M18 line, it benefits from efficient brushless motor technology and is compatible with their robust battery system (sold separately), offering good runtime and power management when paired with an appropriate M18 battery. Some users might find the weight a bit tiring for extended use, and the need to purchase the battery separately adds to the overall cost.

This impact wrench is well suited for professionals or serious DIYers who need a reliable, high-torque cordless tool that balances power and handling, though newcomers should prepare for the upfront investment in batteries and charger.

It delivers very high torque, with up to 1030 ft-lbs for fastening and 1400 ft-lbs for breaking loose stubborn bolts, making it suitable for demanding tasks like automotive work or heavy machinery maintenance. It offers four speed settings and a variable speed trigger, which gives you good control to avoid overtightening or damaging fasteners. The built-in Precision Wrench control further helps prevent mistakes when tightening.

Regarding battery life, it depends on the separate 20V MAX battery you use, but the tool includes BatteryGuard to reduce battery wear and improve durability. Weighing 6.4 pounds, it's on the heavier side for a cordless impact wrench, which might cause some fatigue during extended use; however, the design aims to provide comfortable handling. The plastic body with a robust build and shock-absorbing battery connection adds durability to handle tough conditions. An LED light on the tool helps illuminate dark work areas, which is a practical plus.

The battery is sold separately, so you'll need to factor that into your purchase.

Weighing about 4 pounds, it strikes a good balance of power and portability, though some users may find it a bit heavy for extended use. The ergonomic design and built-in LED light help with comfort and visibility in tight or dark spaces, enhancing user experience. Durability is supported by its metal construction and spark-free motor, but it is not recommended for very large trucks or heavy-duty commercial use.

The kit includes useful accessories like multiple socket sizes and pins, allowing you to start work immediately.
